Intrepid :: 1997 - Coolant Leakage From The Front Of Engine
Nov 13, 2015
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.

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.

I got a 99 v6 passat and it looks like I'm leaking coolant from the back of the engine, like under the TB.

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.

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.

I've got a 1997 Dogde Ram 1500 Pickup. It's got a major coolant leak that seems to be coming right from the middle of the front of the engine. I can't see where it's coming from. I changed the thermostat and the water pump, but it seems to be even behind that. There is a rubber hose that comes off the water pump and disappears between the two banks. I can only see a tiny end of it, where it goes. It looks like getting to that would involve taking off the whole intake manifold. If that's the case, I might as well total the truck. I dunno...

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.

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?

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.

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?

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.

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?

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.

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.

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.

I have a 02 cavalier 2.2 it just started leAking coolant when in a drive thru. Steam started coming up from hood. When I looked under the hood the expansion tank was hissing and it looked like the antifreeze was coming out of the overflow tube at the top of the tank. What should I do? It is sitting still at the parking lot

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.

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?

Here is the history of the car. 1997 Dodge Intrepid, 3.3L V6, close to 200k miles. Bought used 8 years ago.
Engine was replaced by previous owner due to front end accident at 90k (about, memory is fuzz on the full miles). Previous owner was a sales lady and had a repair log. Kept car running like a coo-coo clock since work paid for the maintenance. Her insurance paid for the repair then her work would not continue to pay for upkeep, due to accident. Since I bought the car, I kept in the same frame of mind of maintenance and upkeep.
- Oil is changed regularly and on time (no burning or loss, still filled to levels with synthetic high mileage oil) (Color - maple syrup amber, due to be changed in 500 or so miles)
- Water pump changed 3 months ago (no oil in the res. tank)
- Alt. changed in 2006 (30 - 35k miles ago)
- Ignition Coil and spark plug wires in 2006 (30 - 35k miles ago)
- Battery replaced in 2007 with a new one)
- Spark plugs last Feb. (about 10k miles ago - Look semi clean and are all gaped still to the manual specs) as well as the 2 belts on the engine.
(Timing chain same age as the replaced engine at 90k)
- All the instrument panel lights work, as well as head, turn signals, interior and tail.
Has for a long time (4 years or so), has an engine light on for an O2 sensor (Code 0134 and the meter I have).
The exhaust system had disconnected from the Catalytic Converter (engine side) last winter (9 months or so ago) due to weathering (clamps rusted off and pipes separated). Recently I repaired this 2 weeks ago (noting heavy black soot in the pipes and around the area on the underside). Once replaced had a cloud of soot when I floor the gas hard while driving.
Yesterday while driving after 10 mins from home while accelerating I noticed a loss of power (slowing down) instinct was to press the gas, did so, and slowed down even more. Car drifted to a stop, engine power was also gone (power steering was gone also). When this happened, there was No banging, or clunks, or loud sounds, or overtly ominous clouds of smoke. Engine turned off (while costing to a stop the engine acted as if out of gas - hence no power steering). Got a tow home.
The starter turns the engine over with no clatter, banging, or clunks. No backfires or "Coughing". Same sound as of before, but won't catch and run under own power. (Still acts like no gas, but has half a tank) (battery still has a full charge - spark plugs still spark - took one out of engine while still connected to spark plug cable grounded to engine for testing. No overtly heavy gas smell or residue on plug or during test).
My friend who assisted in the exhaust repair says that it is not the Catalytic Converter being clogged (I believe it is). His suggestion is a faulty sensor somewhere else, maybe cam/crank sensor, maybe MAP sensor, maybe ignition switch, bad EGR or even a bad ASD relay. Don't want to be buying parts to no end on this, need other input to narrow down a direction.

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.
