Civic - Honda :: 2001 - Engine Overheating - Coolant Leaking?
I drive a 2001 Honda Civic EX and have over 248,000 miles. Almost at a quarter million! Recently, the engine has been overheating. The coolant has been leaking and the coolant reservoir would becomes full. I've checked out the fan and the fan relay and both seem to be fine. The temperature seems to increase (to redline) during traffic jams and any times of idling. When I blast on the air conditioning, the temperature seems to decrease, but would later increase when the car idles. The temperature also decreases to normal when I sustain my speeds over ~60mph. Also, the temperature will fluctuate from cold to hot to cold. What does this all mean?

I have a 2004 Honda Civic ex coupe. I have changed the thermostat (twice), fan sensor, temp. sensor. The fan works and when doing an oil change the oil looks normal. No white smoke coming out of my exhaust and I got two radiator flushes, no dirty coolant, and I have replaced the cabin filter. The car doesn't overheat as long as I keep my temperature on hot. If I were to change the temp. to cold it seems like the coolant goes into the reservoir, but it seems like it doesn't go back into the engine. The mechanic that did the flush said that the hoses doesn't to be clogged because the coolant that was removed was green. They stuck an air blower in the heater core hoses and to show that was not clogged as well. The AC worked, I haven't checked in about couple of months. Also when the car overheats there is no smoke coming from the engine. radiator has been burped as well.

I have a 2000 honda civic ex that I recently bought used. It ran fine with no problems for a good month then the check engine light came on and it started overheating. I could smell burning oil and see smoke rising from the hood. I checked the coolant and it was all out. So I filled it back up. Drove about 20 miles and during the drive when sitting idle the car would shudder and jolt around for a second, after about 20 miles I could see the coolant that I just filled up was all gone. I could hear some bubbling sound, all of the coolant had burnt away and was steaming. I did some research and it could be a blown head gasket, but I'm not sure and was seeking how to fix it or to clarify if it was a head gasket.

I have a 2002 Honda Odyssey with 260,000 miles on it. It started randomly overheating this hot summer we have been having. We change the thermostat and flushed the coolant/radiator and still overheats. I do not see any leaking on the garage floor but am loosing coolant and need to put more in about every 14 days. I do a lot of highway driving. What should I look at next?
View 3 RepliesOverheating - Coolant - Honda - Odyssey - Radiators :: 2007 - Warm Air Not Coming Out
Last week I drove my 2007 Honda Odyssey with about 100k on a 4 hour trek in the cold, and all of the sudden the heat stopped working. The fans were blowing, but warm air was not coming out. It was Christmas eve and nothing I could really do about it, so let it be. Drove another 10 minutes that night with no heat to my destination, and many hours later still Christmas eve I drove another 15 minutes. Heat didn't work, but car operated just fine.
Christmas day, drove the car for about 20 minutes with no heat, and all of the sudden the temperature gauge skyrockets, and the engine light goes on, the car is clearly overheating (could smell smoke from the engine). Let the car cool for the rest of the day, check it and there is no coolant at all. Had a local mechanic check some other things like the thermostat but found nothing, so refilled the coolant, and drove 4 hours again with no problems--heat works and everything. I was expecting to have to stop all the time to refill the coolant, but didn't have to because it never leaked on the entire trip. I took the car to the Honda dealer and they check it and find no leaks and nothing else wrong with the car, and offer no explanation on how the coolant magically disappeared, only confirming that they cleaned coolant which had leaked/spilled all over. The only possible explanation was that I had some work done on the car a few months ago (new belts) and the mechanic I used didn't flush the coolant properly.
Heaters Overheating Engine - Coolant System
Had a lot of problems with my Rover streetwise's heaters / overheating engine. Firstly, the heaters were rubbish & took ages to heat up. I took to garage and they pressure washed the coolant system to clear any blockages. This didnt work so they changed the thermostat - this has worked the time it takes to heat up but now when i use the car for the first trip of the day, t as soon as the engine has heated up & the speed hits 50/60 mph, the temp gauge shoots right up to the red zone - so have to reduce speed. The 2nd trip of the day, it seems to be fine - its literally just on first use of the day ie to work.
All oil & coolant looks fine and the head gasket was replaced summer last year.
Overheating :: Coolant Overflow And Failure To Return To Engine?
I know my car has a leak. Blok check test confirmed. Symptoms:
Car overheats after driving for awhile but only intermittently
Overflow is filled almost to top after driving and has wet sides.
Coolant fails to return to engine.
Here is the interesting part. I removed the lid for over flow and took out the hose and exposed it to air. Then I took off rad cap. Instant suction and collapse of both lower and upper hoses. Why did this occur? Bad rad cap and or/ blockage?
Cavalier - Chevrolet :: Overheating When Engine Work Hard And Coolant Leaking
My 1994 chevy cavalier is overheating mainly on hot days and when I work the engine hard. My coolant level hasn't dropped in a long time and the coolant cap is usually dry. I replaced the thermostat and checked the radiator hoses. They seem to be fine. My engine is leaking coolant.

Golf IV / Jetta IV :: 2001 - Engine Overheating - Coolant Temp Sensor Replacement
My temperature has been randomly dropping, them back to middle, and recently my engine was overheating because I'm guessing the fans didn't turn on, because I'm also guessing, the engine didn't know it was overheating?
Anywho, during my replacement, I made sure to get rid of the pressure, and the car was cold. I tightened the cap again, but when I took the sensor out, all the coolant spewed out.
Now if I understand this correctly, do I have a leak? I figured the leak I had was coming from the temp sensor as it is.
Here's some pictures for those who'd like to see ....
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.
Honda - Accord :: 1998 - Check Engine Light Came On / Overheating
Out of nowhere my check engine light came on bought some oil thought it was low, and i just recently got an oil change. Checked my sparks and it was okay. Couple hours later my car began over heating With engine light still on, and my temperature gauges increased knew something was wrong, filled it with anti freeze to cool it down, continued driving and the issue continued. Bought me a knew sensor, I noticed it worked but did not fix the issue, my car continues to over heat, couple days later without driving it, this morning on my way to work it was really cold so my car did not overheat, but my check engine light began blinking and my vehicle began rattling from my house all the way to work, for about 9 miles. Whats wrong with it? Is it safe to drive back home after work.??
View 19 RepliesHonda - Accord :: 1997 - Extreme Overheating / Engine Seemed To Pulse With Loss Of Power
97 Accord Lx - 215k miles - 4 cyl. - regular maintenance. It's been my daily driver for over 5 years and been running perfectly.
Yesterday I drove the 35 miles from work back to my town but before going home stopped to visit someone for about an hour. When I came out to leave I noticed a larger than normal amount of fluid in the drive. I just thought it was condensation from the AC and that it was more because it was extremely hot yesterday (100+).
When I got within 2 miles of the house the 1st thing was that the AC was not blowing as cold. I turned it off. Then the engine seemed to "pulse" with loss of power, and the temperature gauge was maxed out. As I pulled into the driveway the engine light and oil pressure light came on.
After it cooled down I checked and the coolant was a little low, so I topped it off. The oil was really low and I added three quarts to bring it to full.
This morning I started it up and let it idle while I finished getting ready (5-10 minutes) and the temp gauge was about 1/3rd of the way up (where it normally is). It sounded, felt, and drove as normal but after a mile or so the gauge was climbing extremely fast so I turned around and took it back home.
What it might be? Water pump?
Honda - Accord :: Engine Oil Filling Up The Coolant Recovery Tank
The engine oil is being sucked into the cooling system and filling up the coolant recovery tank. It's a peanut butter mess. The radiator is loaded also and I can't what the passages in the block look like. Some say its a head gasket but why would crank case be empty. I would think there would be coolant mixed with oil in the crankcase. I think its a engine porous issue. The vehicle was bought used with 133k miles and a 3 month warranty.

We have a 2006 Civic and there appears to be a coolant leak coming from the engine block above the started motor, so it is hard to see clearly. The kids are about to leave for Atlanta (from Iowa) and I am concerned that this could be a crack in the block based on some on-line discussion. Is it risky to send the kids on a 1000 mile trip without fixing?

The coolant is leaking from the gasket that is on the front of the engine. My repair guy suggested that I also do the timing belt at the same time. Do I have any other options? The Honda has 217,000 miles on it.
View 5 RepliesLS / MKZ :: Overheating - Low Coolant
I was having an overheating issue. First thing to check...does it have coolant. Reservoir said yes. Changed thermostat twice. Still overheating. Changed Water Pump & Belt. Still overheating. Decided radiator must be plugged so bought system flush. Opened radiator, about a quart of coolant came out. (BTW even after draining there was coolant reading in the reservoir). Filled everything up, followed the bleeding procedure and no more overheating. I'm not sure how the coolant reservoir works on this vehicle but I don't trust the "cold full" reading anymore.

View 6 RepliesGTI 337/20th Anniversary :: Coolant Bubbling But No Overheating
So I noticed one day when I was standing outside of my car right after I had turned it off that I could hear the coolant bubbling some. I had just recently flushed the coolant, put on a new water pump, thermostat, and put in a new reservoir with a new cap so I figured it was just some air in the system because there was air in the top radiator hose. So I just worked the air out and thought that was it. The next time I drove my car it did it again and there was no pressure release when I took off the cap either. I ended up getting the head worked on (valve job and check the head for warping). Even after all of this my reservoir doesn't seem to build pressure and every time there also seems to be air in the top radiator hose. After the car is warm I can work coolant back in the hose and 5 minutes later theres air back in it. I've pretty much replaced everything with the cooling system besides the hoses within the last year so I don't know what it could possibly be.
View 2 RepliesPontiac - Montana :: 2001 - Overheating / Low On Coolant
I have a 2001 Pontiac Montana that was overheating. It was low on coolant, and using coolant. I took it to a mechanic who checked it out and found exhaust gases in the coolant. He initially told me that it was a bad head gasket. After doing a bit of research, I am told that it could also be an intake manifold gasket. I know I am losing coolant, but I cannot tell where. I don't think it is going into the oil, as my oil level does not go up. I do not see coolant leaking below the vehicle, so perhaps it is going into the exhaust? Or leaking slowly on top of the engine where it is burned off before it can go on the ground.
Is there any test I can do to determine which gasket is bad before tearing into the vehicle? I thought about sending an oil sample off to determine if I am getting any coolant in the oil, but I don't know if that would be useful information at this point.
