Passat (B5) :: Coolant Boiling - Oil In Reservoir
Long story short, I got a 2001.5 1.8t M5 Passat with 63k miles 2 weeks ago.
This weekend I was driving around and pulled into the driveway and noticed the coolant was boiling in the coolant reservoir. It also looked like there was some oil in the reservoir. Take it to the shop, turns out that the plastic impeller on the water pump broke at 64k miles. This is wierd because the car never actually overheated. The mechanic doesn't think that the head gasket is blown or i have a cracked/warped head because the car still runs fine. He suggests I replace the water pump, timing belt, coolant reservoir, thermostat and obviously flush the coolant. I go ahead with the repair since its almost time for the TB anyway.
After bending over and taking it from the shop on a timing belt and water pump repair, I think I am all good. Today I open everything up after a few days of driving around just to check up on stuff. I open the coolant reservoir and there is telltale signs of oil in the coolant. Now i think this was an issue before the water pump went. Searching the archives I see that the oil cooler is a common failure. This could have also contributed to the failure of the water pump and maybe the thermostat, I don't know.
So instead of bending over for the mechanic for a second time in a week , I think I'm going to replace the oil cooler and flush the coolant system again and change the oil myself. Poked around looking at the oil cooler and it seems as if there is the slightest sign of an oil leak on the outside, which could mean there is a leak inside. I don't have compressed air so I'm not sure how I can test the oil cooler for leaks.
I am thinking i need:
-Oil cooler (some suggest S4, some suggest TDI one?)
-Oil cooler gasket
-Feed and return lines
-Hose clamps
-g12 coolant
-Oil filter
-Synthetic oil
Should I replace the upper and lower radiator hoses while I've got the coolant out? What else should I replace while the coolant is out. I see people suggest flushing the system several times. Should i use G12 everytime or can I just use water to flush until its clean and fill with G12?
Passat (B5) :: Coolant Seems Boiling Inside The Reservoir
been working on my passat for the last year oil cooler went bad and also my CCM fried. Anyways got the car running good or so i thought drove the car up the road today and my coolant sounds like it's boiling inside the reservoir.
View 11 RepliesEscort :: 97 - Coolant Reservoir And Radiator Making Boiling Sound
When the car has been running awhile the coolant reservior and radiator make a boiling sound. It really only does it when it's been at idle for a bit. Radiator is full. Fan doesn't seem to come on after it has been running awhile but does when you turn on air. At what temp should it come on? The temp gauge never goes above the middle point so it stays in normal range, even when the tank are radiator are gurgling.
View 2 Replies300m - Leaks - Radiators :: 2000 - Coolant Boiling In Reservoir Tank
2000 Chrysler 300M with 142K miles. Was a very reliable car until recently.
Problem began with boiling coolant in the reservoir tank. Then began to lose coolant at a high rate. I tried stop leak products and replaced the coolant frequently for a couple months. Some of it kind of worked, but the problem always returned. The car drives fine for about 10 highway miles then begins to steam out from under the hood on the passenger side. It gets about half way up the temp gauge, but does not really overheat. I usually stop when it steams out, let it cool, replace the antifreeze, then do it all over again. I've also tried a bunch of other things too, e.g., radiator flush. None of it worked.
The mechanic wants to replace the radiator. Says the system does not have pressure so there's no real way to determine if there are leaks in the engine. But he does know that the radiator is no good. I'm okay to replace radiator, but don't want to do it just to find out ten minutes later that I have a blown head gasket, which I would opt not to fix. I have read the tell tale signs of a blown head gasket, such as coolant in the oil, but there is none. My exhaust is white, but it's 5 degrees outside and it doesn't look whiter. I have seen some coolant on the ground at times.
Ford - Escort :: Coolant Boiling But Not Overheating?
My son has a 94 Escort LX and this weekend he noticed that when he'd stop the car he could hear the coolant boiling. The car temp gauge never registered too hot, and it never lost coolant. We checked the oil and it is not milky.
About 2 years ago it got a new water pump. Last summer a new thermostat, and then earlier this year a new radiator.
Last weekend he was stuck in a huge traffic jam. (4.5 hours for a normally 45 min. drive). I'm wondering if that could have weakened the radiator cap. He's picking up a new one today, but wonder if there is something else we should check?
Ford 7.3L Power Stroke (1999-2003) :: Coolant Started Rushing And Boiling Out Of Top Of Reservoir
Today on a little road trip about 250 miles everything was going well then towards the end i was about to arrive when the temp gauge rose about a quarter inch from where it normally runs and i stopped at a gas station and all my coolant started rushing and boiling out of the top of my reservoir, I let the truck cool down and removed the cap and i lost all the coolant in the reservoir i bought two jugs and filled it back up and fired her up and the temp is back to normal and was not leaking from anywhere.
Hit the road again for the rest of the roughly 35 miles of the trip to my camp no smoking or lack of power then through a little sand and mud and she stayed cool. I was towing a small single axle utility trailer with a atv and was going 65-70 whole way. Truck has never had a problem with anything in the year and a half i have had it. Just hit 250k. What could this have been? Its holding all the coolant its been in there for a couple hours now without leaking. Thermostat maybe stuck for a second? Or a air bubble?
Ford Transmission :: Overheating And Boiling Over - Trans Fluid In Coolant
I have a '99 E350 that sat for a winter. When I started it up, it appeared to be overheating and boiling over. I didn't have time to mess with it, and it sat for another year. Today I tried to figure out the issue and determined that I have trains fluid in the coolant. Pulling the trans dipstick revealed a white milkiness on the dipstick, so I'm guessing the trans cooler/radiator failed and the two fluids have mixed.
My question is, is the transmission salvageable? The van has not been driven in this condition, so I'm hoping there is hope. Obviously, flushing both systems (multiple times) is in order, along with a new radiator. But is there any hope for the transmission? I'd hate to spend the money flushing it all multiple times if it is a lost cause.
Accent LC (2000-05) :: Radiator Is Dumping Coolant Into Reservoir But Not Overheating
My 2000 Accent with 164,000km is not overheating but is dumping coolant into the reservoir so that the radiator is about a quart low. I did have a few problems with it overheating in the past month, but that was solved by thermostat removal (always above 80F here). I stopped before the overheats reached the redline and allowed the engine to cool before continuing, no known adverse performance during the overheats. No water in oil.
Failed troubleshooting:
Drained and replaced coolant x3
New radiator cap
* No thermostat.
Dodge - Neon :: 2000 - Overheating / Car Won't Take Coolant Out Of Reservoir Tank
I have a 2000 Dodge Neon with a 2001 Neon motor in it. I have just recently had problems with the car overheating. So we started diagnosing it and replaced parts that we thought were wrong. We replaced the water pump, thermostat, radiator cap, and timing belt. The problem that I am having is that the car won't take coolant out of the reservoir tank. I have bled the air out of the cooling system and it still didn't fix the problem.
View 9 RepliesPlymouth - Voyager :: 1992 - Overheating / Hole In Coolant Reservoir?
I have a 92 Plymouth Voyager, which I just got back from my son. He was driving it in Seattle for awhile, until it overheated. He had a new radiator and new thermostat put in, but it still overheated. I towed it back to my place to see if my daughter and I could get it running. The new radiator he had put in was leaking from a seam around the top. We replaced that with a new radiator.
I drove around for about 60 to 70 miles, into town and back. No problem. Today my wife and daughter took it to town and only made it about 2/3 of the way before it started to overheat. Daughter discovered a hole in the coolant reservoir. But I am still not sure what could be the reason for the overheating. I did replace the water pump about three years ago. What I can do to possibly repair this problem?
Ford - Exporer :: 1996 - Overheating / Coolant Reservoir Is Super Low To Empty
Had overheating issue with the wife (she doesn't monitor fluid levels like she should). Now you can't operate it for more than a day or two before the reservoir is super low to empty. Mechanic coolant is going into the engine, probably through the intake manifold. Says investigating further will cost a ton. What can I do cheaply to figure out what's going on before I give up? I followed her when the engine was started from cold & could see water vapor (more than I would expect) in the exhaust until when I figure the engine reached full operating temp. It has about 225k and is the 6 cyl engine, btw.
View 1 RepliesSanta Fe (CM - 2007-12) :: Overheating - Coolant Leak / Reservoir Tank Empty
I was driving my 2008 Santa Fe last week (before I went on vacation) and noticed the the A/C wasn't coming through quite a cool as usual (almost felt like the vent was on w/ no AC). Then after about 10 minutes of driving I noticed the thermostat on the car get to about the 3/4 line pretty close to the red lines.
Luckily I was home so turned the car off and popped open the hood. I noticed the reservoir tank was empty and there was some coolant that dripped down on the fans & a small pool of coolant on the engine block right under where the oil is poured. (nothing has been dripping under the car)
I added a little coolant to the reservoir tank and the next time I turned it on and let it run for ~10 minutes, it was the same thing.
Anyway, I came back from vacation and opened the hood to try and identify exactly where the leak was, and ran the car for ~30 minutes, with A/C on full blast and the car didn't overheat or leak anywhere. Coolant tank was still full from when I filled it the first time.
What could have caused the leak/overheating in the first place?
Nissan - Xterra :: 2001 - Overheating / Coolant Bubbling Back Into The Reservoir Almost To The Top
I have 2001 Nissan Xterra SE 3.3L V6. A few weeks ago my car started to overheat while going through the grapevine (mountain pass in SoCal). After filling it up with coolant, I took it to the shop. They couldn't figure out what exactly was the problem. It passed the block test and such. They said the top hose was swelling up as if something was blocking it. They also said my car was going through about a gallon of coolant. They replaced the water pump, thermostat, and the top hose. they also replaced the timing belt.
After driving the car for an hour, it started to overheat again. This time, I took it to the Nissan dealership. They said the timing belt was off by 2 teeth and they think that's why it overheated, so they fixed that problem. They also did a cooling system test and found no leaks.
I got the car back and it still overheats. After the turn off the car, I see coolant being bubbling back into the reservoir almost to the top. Also, my radiator was replaced about a year ago.
Ford F-150 - 1997-2003 :: P0306 And P0174 Codes - Engine Overheating And Coolant Reservoir Dry
I have a 1999 4x2 F150 XL, 4.2L engine, 5-speed trans., about 197,600 miles and have been getting P0306 and P0174 codes. The check engine light came on and stayed on. Also, pretty much randomly, my engine over-heats and the engine compartment coolant reservoir is suddenly dry as a bone. I bought the truck new and this has only happened twice, during normal driving.
Clearing the 0306 and 0174 codes. Not sure what to do about the over-heating thing.. What I've done so far to try to clear the codes is the least expensive stuff:
=> Replaced both forward O2 sensors, have read where the two rear O2 sensors don't necessarily need to be replaced so I haven't replaced them yet. The sensors that came off are Bosch, as are the ones that I bought from Autozone and installed.
=> Replaced old spark plugs with Motorcraft brand, gapped to 0.054 in.
=> Replaced old spark plug wires with Motorcraft spark plug wires.
=> Cleaned the MAF sensor
=> Replaced PCV valve and replaced an section of elbow hose near it. The original elbow had a big hole right at the 90-degree bend, on the inside.
=> Replaced a cracked, dried-out, vacuum hose coming from the evap cannister purge valve and going to the front underside of the upper intake manifold.
=> replaced fuel filter.
After doing all this, I took it out on the road long enough for the computer to wake up and relearn and got the check-engine light again. Only this time it was flashing. I gather from reading in this forum that a flashing CEL is worse than a constant-on CEL so I drove back home and have yet to take it back out.
After reading about problematic ignition coils, I followed a procedure in my Haynes manual to check mine out:
=> Verified the correct resistance values at the electrical connector (0.7 ohms),
=> Verified battery voltage is present at the harness side of the electrical connector (about 12.6 volts),
=> checked the resistance values between the three sets of 'towers'. Starting from front to back, the resistance readings were 13.06 kOhms, 13.12 kOhms, and 12.98 kOhms. The correct range in the Haynes book is 6.5 to 11.5 kOhms so I thought maybe my ignition coil was bad.
I located a Motorcraft ignition coil at a local O'Reilly Auto Parts store, went there, and was able to check the resistance values on that new one. Turns out the resistance on the new one at the parts store is pretty much the same as that on the one on my truck (all three coils were 13.something kOhms), so I haven't replaced the ignition coil. I guess either my Haynes book is probably incorrect or the ignition coil on my particular F150 has different resistance values than the rest of the vehicles covered by that manual.
Next things I'm looking at replacing:
=> egr valve and the associated line to the DPFE sensor. (DPFE replaced a few years back, as a result of a P0401 code)
=> iac valve
=> upper intake plenum gaskets
I'm kind of at a loss at this point. I hate to just continue replacing things without knowing that I'm replacing the right things.
Santa FE SM (2001-06) :: Power Steering Fluid Boiling / Foaming Leaking Out At Reservoir Cap
2.7 Power Steering Fluid boiling/foaming leaking out a reservoir cap!
1) Recently had Timing Belt/Water Pump and spark plugs/wires replaced.
2) Issue started immediately after.
3) Removed most of old PS fluid, cleaned out reservoir w/brake cleaner. NOTE: nothing appeared to be clogging reservoir. Refilled with new PS fluid. Repeated these steps a second time. This appeared to immediately resolve the issues for several weeks.
4) Now the power steering is getting rough and noisy again. Also, the PS reservoir is leaking out of the cap worse than before. It looks like the fluid may be "boiling", but it is definitely foaming up pretty badly.
What my issue(s) may be?

View 13 RepliesSebring - Chrysler :: 2004 - Overheating / Bubbling And Boiling In Water Recovery Tank
My friend's '04 Sebring is still overheating even after these steps have been taken: heads were warped -- had a professional shave them down and rebuild engine; new radiator; new thermostat; then removed thermostat to try this way, and bled the system for air bubbles (more than once).
The car can run about five miles - then bubbling/boiling in the water recovery tank. The mechanic said there is a small crack on the water reservoir (a small plastic box) near where the bolt connects to the engine. Could this crack affect the pressure of the system and cause this overheating?
Passat (B5) :: Boiling Coolant - Engine Compartment Getting Really Warm
I have an 03 Passat Wagon, 2.8L V6. My wife is getting ready for a big drive tomorrow, about 13 hours. Right now after reaching the operating temperature and then shutting off the coolant is boiling. The temp gauge never goes beyond 190 so it is not overheating but it is getting really warm in the engine compartment.
History: I noticed a couple of days ago that the expansion tank was badly discolored and had some corrosion inside. I know it was because I inadvertently mixed the green stuff with it about 2 months ago. I know it was stupid, but that was before I realized how stupid. Yesterday I drained the coolant and flushed it about 4 times. I couldn't flush it completely because I couldn't get at the drain next to the transmission fluid pan. I just drained it from the front outlet.
I refilled the system by disconnecting the expansion tank and holding it up until fluid came out of the hole on the hose going into the firewall. Then I was going to bleed it from the bleeder screw in the rear coolant pipe (as listed in Haynes manual) but could not find it. I even have the photo in the book to guide me and it is not there. Since I couldn't find it I skipped to the bleeder valve by the serpentine belt. I bleed that and hooked it all back up.
Now my fluid boils. I know it isn't the expansion tank cap because I took the one from my Jetta and put it in and it does the same thing. I put the cap from the Passat in the Jetta and it doesn't cause that coolant to boil. After driving today for a half hour the engine compartment felt superheated. Even the fenders were hot to the touch. It is almost 90 outside but it still felt unusually hot in the engine compartment. I would like for my wife to drive this on her road trip instead of the Jetta, but I can't let her do that with this problem.
I think I must not have bleed the system very well. The heater works and the temp gauge never goes above 190.
