Toyota - Camry :: 1996 - Coolant Losing / No Apparent Leaks
I've got a 96 Toyota Camry, 4 cyl, that appears to be losing coolant. I do not see any apparent leaks. I've checked compression and all cylinders are 170lbs. Within the past year I've replaced the radiator and hoses, timing belt, water pump, etc. Within the past month I replaced the thermostat and radiator cap. I do see it bubbling in the overflow tank. Also you see vapor with the radiator cap off. I feel sure its probably a head gasket ..

Have a 2002 V6 in the family that's losing coolant at a rate of about an expansion tank every 3 -4 weeks.
I have searched all around with a flashlight, don't see any signs of coolant residue near the radiator, expansion tank or cap, water pump, or heater core connections. Heater core does not smell like coolant. Exhaust does not smell sweet or does not steam once the car is warmed up.
I pressure tested the cooling system on up to 18-20 PSI and still can't find any evidence of anything leaking out anywhere.
I'm going to change the upper and lower radiator hoses this weekend in the thought that maybe it's a pinhole leak once hot and under pressure (I pressure tested cold). Any common things I'm missing where it may leak?
LeSabre :: 2001 - Buick Losing Coolant
My 2001 Buick Lesabre has always shown to run exactly normal on the temperature dash unit until recently. I checked my coolant level and it was a bit low, so I added. After I filled the radiator I have noticed a coolant leak spot on my driveway, after I drive it now. I have removed the gravel shield and have tried to pin point exactly where the leak is coming from, but cannot. Now, each time I park, after driving it, I put a clean piece of cardboard under it to try to see exactly what area the leak is coming from. Last night I put the car on ramps and crawled under to discover that the leak is located just above the oil filter and is actually dripping from the oil filter, but I still cannot see the exact location of the leak.Actually the leak does not appear until about an hour after I park the car, so it sounds like something is contracting after the engine has cooled off, but what? The leak has seemed to be getting worse each time I drive the car. How can I determine exactly where the leak is coming from without just changing a bunch of parts.

I'm pretty new but we have an '02 Passat (68K miles) that has been pretty trouble free until lately. I'm losing about a 1/2 quart of coolant every week to 10 days; just enough for the coolant light to come on. The car never overheats and the oil looks clean (not milky). But I can't find the leak . I do see some dirt and grime build up on the front of the engine as well at the rear of the engine near the tranny, but nothing definite..

I have a 2005 Chevy Cobalt, 2.2L engine and am having a few problems. I believe I am losing coolant somewhere, but cannot ever see any leaks or anything on the ground where I park. I am having to top off the reservoir a couple times a month with water/coolant to keep the temperature from going up above normal (which I've found is around 190 degrees). I first noticed this when the temperature had reached 230 degrees! I also hear a sound like sloshing water in the front end when I first start and drive the vehicle. The sloshing usually subsides after I've been driving for several minutes. To top it all off I now have a bit of foam on the oil cap and the oil looks a tad bit cloudy.

With a cold engine in my 2010 Forester (29,000 miles), the coolant level has dropped from "full" to "low" in the overflow reservoir over the last 8 months or so. The level was down at that time (8 mos. back) and I topped it off. There is no obvious coolant puddle on the driveway. There is a gurgling sound at tailpipes and the exhaust is very wet. I'm worried there is a cooling system leak into the engine. Overall I have not been happy with the service dept. at my dealer (bought the car used from him) and wondering if this is the type of diagnosis and repair that an independent shop could handle.

I am currently driving a 98 Buick with the 3.8 V6 and 120,000 on the clock. The car runs 100%, and its paid for
My problem is I seem to be losing coolant, at the rate of about the entire overflow in 2 weeks (I only drive on avg 15-20 miles a day). The problem is I have no leaks. I even went so far as to pull the spark plugs and they all looked good (none of them looked "steam cleaned"). I put florescent dye into the rad, and I can’t find a drop of coolant anywhere. The intake gaskets have already been done on this car, and I triple checked around it with the die.
Rad, and hoses all check out, no dye in the oil, no dye at the heater core/AC drain under the car, the core plugs are fine, around the head gaskets seem fine as well.. I CANT FIGURE THIS OUT !! I am 100% losing coolant, but I can’t find hide nor hair of it..
I know I can keep adding coolant, but I like my cars as leak free as possible and if it is something bad, I want to know about it now not later.
Chevrolet - S-10 :: 1999 - Overheating / Losing Coolant From Block
I have a 99 S10 4.3 2wd. Last week on a 5-6 mile drive it overheated, and it turns out the coolant was somehow almost a gallon low! I topped it off and all was well for nearly a week. This weekend I was driving and suddenly could smell a strong coolant odor. The temp gauge began to spike and when i pulled over and popped the hood it was clear the coolant was finding its way out but not through the overflow or radiator. When it cooled down and I added water/coolant I could see the coolant coming from the block or near the block. Also, when I let it run for a few minutes i could see the fluid "spraying" out from what appears to be near the pass. side valve cover maybe near the intake manifold...The oil looks good, so I'm not sure it's the head gasket. Not sure where to go with this.

1989 3.0 shorty - 135K on her - and at 21 years old, the original radiator finally failed with a hair line crack, and so I bought a plastic on, from on of the part stores, put it in, and now it takes on like a gallon a month of antifreeze.
BUT I see no leak at all... the engine runs fine, and not head gasket or crack head (been there done that with the explorer I have). I don't smell it either really -heater core is dry... as is floor underneath. Need replacing the Radiator?

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 RepliesFord Aerostar :: 1989 - Losing Coolant But No Leak Found?
89 3.0L - I seem to loose a little bit of coolant every time I drive maybe like 1/2 a pint?
I checked every connection - engine running, and even waited to make sure the t-stat was opening, and closed, etc (maybe it was the top hose, nope)
I did replace the radiator a couple of years ago, and had the problem ever since I did that, but at the same time, I also replaced the T-Stat with a 165 degree, since she was starting to run a bit on the hot side, even with the new water pump and radiator I did... on a cool day, it would run at the middle of the gauge with a 190 degree... and with AC on, hills and 95 degree days, it would be pushing upwards of 3/4 of the way on the gauge...
Could the 165 degree therm stat be somehow causing a 13 lb cap to not function properly? I replaced the original with a Stant... but Im thinking I should get a new Motorcraft OEM cap, since the other one lasted 20 years!
I kept the old radiator - love it - "wow real brass/copper in there!" it was still fine when I pulled it, but had a hairline crack right below the top hose area...
Anyways, pressure tests revel nothing, I see no bubbles or anything with the engine idling, cap off
Century :: 2002 With 3100 Engine - Losing Coolant And Lots Of Sludge
A friend of mine has a 2002 Century with a 3100 engine, 65,000 miles. The car has been well cared for, with all regular maintenance performed on time.
The car is losing coolant, the low coolant sensor comes on every few hundred miles. The local garage has added coolant, replaced the coolant sensor , and flushed the entire system. At this point my friend asked me to have a look.
1) Slimey "milkshake" on oil cap. Cleaned & dried it 4 days ago. 100 miles later, it's all slimey again.
2) Rad cap also has slimey gunk on it.
3) Coolant recovery tank is CRUDDY. The walls are all darkened with what I'd assume is oil residue.
Now, before anyone starts saying this is normal with Dexcool, I'll mention that I have a '98 and an '02 Grand Prix with Dexcool, they have 218,000 and 158,000 miles, respectively. My oil caps are bone dry. My coolant caps have only Dexcool on them. And my coolant recovery tanks are so clean they look new.
In seems to me that there is some kind of internal issue, e.g. intake manifold gasket, where the fluids are mixing. FWIW, I don't see any sign of external coolant leakage. Do the 3100s have any known issues in this area? I suggested my friend have the Buick dealer pressure test it (when it's cold), and go from there.
Civic - Honda :: 2005 - Running Hot / Losing Fluid From Coolant Reservoir
So my civic has been running hot this week. Had plenty of antifreeze. Oil.changes and tuneup are up to date. Started running hot monday so I went ahead and changed the radiator cap and replaced the thermostat. Still running hot at this point and im losing all my fluid from the coolant reservoir. I run my heat as a guide to when I lose all fluid. Once the heat turns cold I pullover and refill it up. Oil isnt milky and no white smoke. Could it still be a bad head gasket? Possible water pump? Plan to flush the radiator tomorrow.
View 4 RepliesHonda - Accord :: Reservoir Tank Losing Coolant - No Leak On The Ground
A few weeks ago my car over heated and stopped. I had it towed and the mechanic changed the water pump, timing belt, gasket cover and more. About two weeks ago I noticed antifreeze on my drive way. Took it back in and the mechanic changed a clamp on the radiator. it continued to leak antifreeze. I took it to Pep Boys for a pressurized test, they couldn't find a leak, but did say my radiator hoses needed changing and they suspect the radiator cap is the problem. That was a week ago. I just got back from vacation and the reservoir keeps getting low every day, but not at the minimum line since the first mechanic filled it to the top. There is not apparent leak under neath the car. No smell when I start. Oil is not milky. Called first mechanic he said sounds like a blown head gasket....
Car is Honda Accord 1999, 138K miles.
Chevrolet - Tahoe :: 2005 - Coolant Temp Gauge Went All The Way Down To Nothing - Losing Pressure?
We have a 2005 Chevy Tahoe. Been running great. Has 140,000 miles on it 80% open road. Couple of weeks ago was highway driving and noticed the coolant temp gauge went all the way down to nothing, and then back up to normal (middle of the dial) This happened 5-6 times and each time as the temp rose back to normal, the transmission would lurch.
I took it to a mechanic who could not figure out what was wrong, but acknowledged it was running terribly. He said that was what he would try before going to a dealer. I agreed and the car instantly seemed to be running perfectly. Now a couple of weeks later, the coolant temp gauge is dropping again. It is not going all the way to nothing, and the transmission is not lurching. It goes down from half to a quarter and then back again. So something still seems to be wrong. Otherwise all seems to be well.
Ford 7.3L Power Stroke (1999-2003) :: Losing Coolant But Only At Low Elevations?
Since changing to ELC a couple years ago, my truck will leak a small amount of coolant when I stay over night at the beach house. I haven't noticed any coolant leaks at any other times. I was down there Saturday night and it leaked about two or three tablespoons of coolant over night. I drove home Sunday, and my truck has been parked in the same place for almost 72 hours without a leak. This has happened a couple dozen times over the last two years. The elevation of the driveway at the beach house is 6' above sea level. "Home" (around Houston) is anywhere from 35' to 80' above sea level. Is there any way that the lower elevation is causing this leak? I'm pretty sure it's coming from the thermostat housing, but because I replaced the upper hose, I can't tell if the dried ELC around the housing is new or old.
View 12 RepliesFord F-150 - 1997-2003 :: Losing Coolant / No Heat Coming From Vents
About mid-October I noticed when it as real cold out and I had the heat running whenever I would come to a stop I noticed there is very little to no heat coming from the vents, despite the engine being warm and running at operating temps. At the time I was working for a shop and I asked one of the mechanics what the problem was. He said that it was the radiator not having enough coolant.
Turns out when we pulled the cap the coolant res, was just about bone dry. So we added in about a gallon or so of coolant with the truck running and sure enough at idle the heat was back.
Fast forward to the last couple of weeks and when I am sitting at idle again same thing happens. So somehow the engine is losing coolant. Its not ending up in the oil (no white on the dipstick) and there is not a coolant leak. As it sits there is 255,300 miles on the truck now. 1999 5.4L F150....
Ford Ranger / B-Series :: 1999 - Losing Coolant Internally / No Water In The Oil
1999 3.0. Been losing coolant internally. No water in the oil. Been back and forth on doing a full engine swap (its got 250k on it). So finally decided to just try the head gaskets. Anything out of the ordinary on these? Anything to look out for? Any special tools?
