Camry :: Coolant Leakage After Engine Shut Off
Ave an 02 Camry 4 Cly
Noticed small puddle of coolant under the car - then noticed overflow empty and radiator a little low on fluid. Noted some coolant below the thermostat.
After filling back to proper levels, ran engine for a while with no apparent leaking. Took a couple of short trips and inspected after each trip and no leaking noticed.
Checked several hours later and noted coolant below thermostat housing and on ground. After a couple more trip noted coolant level dropping again.
What would cause fluid to leak after engine shut down? Could be coming from another location, but my attention is on the thermostat at present.
Prius (Gen 2) :: Engine Coolant Pump Replacement Due To Leakage?
I'm sitting at my Toyota dealer where I bought the car 3 weeks ago. My car is in because it needs to have the engine coolant pump replaced due to a leak. Is this a common fix for the gen 2 Prius? Fortunately this is getting covered under warranty.
View 4 RepliesIntrepid :: 1997 - Coolant Leakage From The Front Of Engine
My 97 Concorde 3.5 w/ 223k developed a second coolant leak from the front of the engine. Using a pressure tester I found it was leaking from the water pump housing o-ring (pass side) and also the o-ring behind the water pump itself. I did this exact repair 3 years ago including new pump! I do everything meticulously so this has me a bit frustrated. I've got it all torn down and cleaned up real nice, except there seems to be a lot of pitting in the o-ring grooves on the back of the water pump housing, mainly the large one.Can I use high temp RTV oil-resistant sealant in the grooves and then put the new O-rings in to make sure they don't leak from the pitting?
Also, I found the cam thrust plates to have hard, cracked seals.
Passat (B5) :: 2000 - Bad Motor Include Rough Idle / Oil Leakage / Coolant Light Comes On
I just got a 2000 Passat 1.8T with a bad motor.
Symptoms include: rough idle, oil leakage, coolant light comes on after running for about 2-3 min., I checked the coolant res. and it has what I suspect is oil in it. I know that the PO ran cheep oil and oil filters the last 2 oil changes and this has caused the famous cannibalization of the engine but what I need to know is would this feed oil into the the coolant over flow tank? There also seems to be some oil/coolant seeping from the upper left.
The car only has about 90k on it and most of those are highway miles, other than cheep oil, the car has been very well taken care of.
Explorer :: 2003 With 4.0 Engine - Coolant Loss And Smell But No Leakage
I have an 03 Explorer with the 4.0 engine. There is a strong smell of coolant and the reservoir does go down slightly once a week or so. There is No Leak whatsoever that I see, I have checked under the hood, under the vehicle, under the dash, everywhere...nothing. Where is the coolant going? This seems to be a common problem, I work at a quick lube and almost all of these explorers are low on coolant when they come in.
View 2 RepliesCelica :: Disappearing Coolant - Gas Leakage
Bought a 1988 Toyota Celica GT Convertible. I am losing coolant. So far I have done the following: used a leak down pressure tester that shows I have a leak; looked under car for leak and didn't find one, put UV test fluid in radiator, doesn't show any external leaks and doesn't detect any coolant in exhaust; there is not coolant dripping from the heater (passenger side floor); the car does not overheat - the temp gauge shows it in the middle; the car runs great; just had emissions tested and passed with flying colors.
View 12 RepliesPrius (Gen 2) :: AC Won't Work Due To Coolant Leakage
I have a 2006 Prius. I must admit that I've never been satisfied with the A/C performance, but now I'm even less impressed.
I had the A/C system serviced at an "after market" place as our dealership calls them (about 2 weeks ago). They added just under a half pound of coolant, oil, and UV dye. The system was much improved after the "after market" shop serviced it and stayed that way right up until it stopped cooling. Two days ago, the A/C stopped cooling and I'm in town so I stop by the dealer. They do the same basic checks I did with the same results - checked the fuses-OK, checked the lines and connections with a UV emitter-OK.
They evacuated the system - removing 0.16 pounds of whatever was left in the system - and recharged the system with 1.06 pounds of 134a, etc.
Neither of us could detect a leak, assuming there was actually dye in the system.
There is no problem with the compressor .
They see no other issues with the A/C system, it was just out of coolant.
Where did the coolant go and why is there no visible evidence of a leak?
Aside from monitoring its effectiveness and checking for dye leaks, is there anything else I should check?
Should the sight glass have enough dye exposed to detect inside the system with the UV emitter?
What should I see (or not see) in the sight glass?
Aurora :: 2001 / 3.5L - Coolant Seems Low But No Leakage
Just had to replace the steel line that runs from the motor to the firewall with a rubber heater hose due to the steel line rusting through and spraying coolant around. (i left a steel section above the head along the firewall due to heat concerns. I refilled the system through the reservoir but I hear coolant sloshing around in the heater core and the low coolant light is popping up.
The coolant is not low in the reservoir but I really do not feel like the lines were filled when I added coolant to it after the repair.
The temp sensor indicated the car was running normal temp range and the car ran fine when I gave it a 6 mile test drive following the repair. No leaks in the new hoses.
Silverado :: Coolant Loss - Fluid Leakage When AC On
So, whenever I park the car after a trip it always leaks fluid when the A/C was on which I know is normal but now it seems to leak a lot more and I'm wondering if that's where all my coolant goes. Where exactly does it drip from from the A/C? Is that somewhere in the cowl?
View 8 RepliesPrius (Gen 3) :: Coolant Touching The L Mark, Might Be Leakage?
A couple years ago noticed the coolant + inverter reservoir was on the low side. Took it to the dealer who pressure tested it and didn't find anything wrong, added a bit, and said good to go. Roughly 55,000 miles.
Today at close to 85,000 miles the coolant in both the radiator tank and the inverter is again touching the "L" mark. They were filled up to the middle/almost topped off after the dealer visit.
Just curious if others have had this issue and/or where to look. I haven't touched the coolant since purchasing at 42,000 miles in 2011.
This is the only issue I've had with this car so far. But it scares me, as coolant loss can be a big deal! Something as small as this isn't as concerning unless it's leaking some place I don't know about, or being consumed in the engine.
Prius (Gen 2) :: Coolant Leakage From The Throttle Body
My prius has a coolant leak, which look like it's coming from the throttle body. The stealership recommends a new throttle body. The mechanic said he has not seen coolant leak from the throttle body before. Is this the only fix to replace the throttle body?
View 8 Replies7 Series :: Intermittent Leakage - Seems Oil Getting Into Coolant System
A few months ago I purchased a 1990 735il and have had cooling problems with it ever since. It started with intermittent leaking at the seam where the lower radiator hose meets the thermostat housing. Eventually, the lower radiator hose blew out. I replaced it, but as soon as I started the car it immediately overheated. My next step was to change the thermostat. (Note: When I removed the old thermostat it was obvious that the person who had installed it had snipped off the inner portion of the thermostat. I don't know why someone would do this, but I figured it must have some significance). When that was done I thought I had solved the problem. The car drove perfectly on a 50 mile drive after replacing the thermostat. A few days later I was sitting at idle and the car began overheating again. I shut it down, let it cool off and drove home without issue. It now seems to run fine and the temp gauge stays at 12:00 as long as I keep driving, but when at idle it seems to overheat.
It should also be noted that there seems to be some oil getting into the coolant system. I am making plans to replace the head gasket at this point, but only seems to be a one way problem as there is no evidence that coolant is getting into the oil.
Prius C :: Found Wet Back Seat, No Leakage Appeared
I recently noticed that my back seat was all wet. It appears water is coming in from the middle of the seat and spreading outward as far as I can tell. The car has been parked outside overnight. All four windows have been rolled up and there is no water in the trunk.
View 3 RepliesMontana :: Coolant Leakage Only At Operating Temp And Under Pressure
2003 Pontiac Montana 3.4 L
225000 Kms
Intake Gasket replaced already at 60,000 kms (yes a while ago)
Recently, noticed a major external coolant leak at the front of the motor (passenger side). It only leaks when at operating temperature and under pressure. It does not leak when you first start the engine, it takes a while before it leaks.
I replaced the rad cap, just in case it was faulty. Upon the second test, after getting it running good and hot, it leaked again. But only when at operating temp. It is not overheating.
Problem is, as the coolant is leaking out, the main drive belt is splashing the coolant all over the place and thus I am having a heck of a time pinpointing if it is a head gasket or intake manifold leak or perhaps somewhere else.
I can't take things apart to get a better view, because it needs to be running at operating temp to get the leak. If I pull anything apart for a better view, I won't be able to start the engine to reproduce the leak.
Prius (Gen 2) :: 2005 - Leakage By Coolant Filler Pipe
I was changing the engine coolant on my 2005 Prius today. When I went to fill up the tanks, I noticed a small pool of coolant right under the filler pipe. I thought I might have overfilled something, but when I jiggled the filler pipe, I heard an air leak. It looks like there is a bad seal between the filler pipe and the radiator. I also noticed that my coolant recovery tank was empty. I never noticed this before so I don't know if this issue is related.

View 3 RepliesImpreza :: Coolant Leak But No Visible Sign Of External Leakage
I've had to replace my radiator twice due to it overheating. I am noticing coolant level going down but I'm not seeing any signs of an external leak. My garage is saying it is probably internal and going into the engine. Says I probably have to replace the head gasket but that will be very expensive.
Could I get some further feedback on what it could be and what else I could do? I am also getting a check engine light on a "lean mixture" issue. Not sure if they are related.
Corolla / Matrix 2009-13 :: Loss Of Coolant - No Sign Of Leakage
I have a loss of coolant, and I can smell it as I drive. I looked under the car today every hose is dry to the cooling system, so I thought look where the heater core is, everything is dry there too. No sign of Head gasket leak either. I just can still smell it, and still losing some but it is very little. What should I look for next?
View 2 RepliesFord Excursion :: 2004 - Coolant Leak Running Down The Back Right Side Of Engine
I have an 04 Excursion with a 6.0PSD. I am currently experiencing a coolant leak, not very bad at the moment but I would like to fix it. The coolant is running down the back right side of the engine and I can see coolant pooling on the pan on top of the motor, specifically the right side. I can see some moisture on the front of the engine but it is below the top of the engine and I do not think this would be the cause since coolant won't flow up hill. I can't see or smell any coolant flowing when the engine is running but see it at idle and when parked.
View 5 RepliesGrand AM :: 2000 GA 3.4L SE (base) Sedan With Intake Manifold Coolant Leakage
I have a 2000 Pontiac Grand Am SE sedan (base model) with a 3.4L engine at 142Kmi that was just diagnosed with an intake manifold coolant leak by an independent shop.
I've done some googling and found that this is a known problem with this engine (including a class action suit). So far the leak is just external; no coolant in the oil and no oil in the coolant.
