Pontiac - Grandprix :: Coolant Disappearing But No Apparent Leak - Rust In Radiator
Feb 18, 2015
I have coolant disappearing but no signs of a leak anywhere. Oil is fine. Car does not run hot. There is rust in the radiator though. Heater core is not leaking. I have a 2001 Pontiac Gran Prix GT. There was a recall on the cooling system but was not serviced (I didn't own car then). A pressure test was done and it holds pressure. Should I change radiator and thermostat? What else should I have checked?

I have a 97 Grand Prix GT with a 3800 engine. The "low coolant" light comes on occasionally, I checked the coolant in the radiator and reservoir, both are fine. I replaced the radiator cap. There are no signs of engine overheating. Could it be the thermostat? Also where is the sensor located?

I have the 3.1 V6 in my 2001 Pontiac Grand Prix and today it started spewing oil out of what looks like an electrical plug in the front, toward the bottom just under the valve cover, dead center. What is this plug?

Even though I had head gasket done/timing belt/water pump & other stuff, 3 months, ago, I'm having to check the coolant level weekly & adding about 1 cup of water to pink coolant every 8 - 9 days. The mechanic who did the work tells me that adding that "little" water in "that amount of time is nothing unusual". I know of no one else who keeps a coolant log. I'm obsessed with this problem. I've spent so much on differing repair to this car - it's as if I bought a lemon.Car has 104K mi. Have coolant problem with no coolant winding up on the ground?

I was searching for an oil leak forever. In my search for the leak I resealed my hpop, redid oilcooler rings and last week had a friend pull my motor to redo the pan gasket. The leaks were almost down to where I thought we had them beat. Now in the last couple days I'm losing coolant and oil....bad. there is oil on the ground mostly from the cross member. Question is did my oil cooler fix not take? I have read that a nicked of ring can cause this.

I've been smelling coolant for a few weeks with no apparent leak. Walk out today, small puddle under truck. Coolant running/drip along seam of engine and trans right in front of downpipe on passenger side. Even with a mirror I can't see up far enough. Looking from top is impossible. What could be leaking up there? Turbo?

Will start with the back story, i have a 2007 G6 V6 that had a slow leak in the radiator. I kept it full and it only went higher than normal once but i noticed it right away and didn't let the needle peg at hot so I've kept it full, checking it every time I went somewhere. the other day on my way to work the needle pegged at hot and the temp light came on so i pulled over right away and shut the car off and let it cool for an hour and added some more coolant. started it up again and the temp stayed normal for a minute so i tried to get it back to the house when the needle pegged, i lost power and the check engine light came on. i stopped the car and called a tow and while waiting on the tow truck my battery died and all i had running was the hazards. the only thing I noticed was the leak in the radiator had gotten worse.
After I got it home and let it sit for 5-6 hours i got a jump from my neighbor and I noticed I wasn't getting any circulation, the reservoir was still full, the check engine light came on and stayed on, and within a minute or two the temp was rising fast so i shut it off and haven't touched it since except to check the oil which looks, smells, and feels fine and is at the proper level and didn't see any oil floating around the overflow tank. and while the car was hot I didn't see any smoke or steam coming from anywhere aside from the leak in the radiator, the water pump pulley was spinning fine, no whining or whirring sounds. i did notice that the plastic piece where the metal overflow line attaches to the engine was badly cracked but wasn't leaking.
I'm thinking maybe the water pump went out and/or the thermostat is stuck closed and caused the overheating issue. as far as the check engine light goes, could that cracked plastic piece cause the check engine light to stay on?not sure if there's a sensor involved in that or not. or could it be the low coolant sensor causing it as the block has no coolant in it?

I've been driving a 2006 Liberty with 110,000 miles and have had no problems for about 6 months. I didn't get a tune up at the behest of the previous owner who had showed me records of the last time he had it tuned up. I didn't notice that he hadn't flushed the radiator, however. Since the cold weather started, I've been very cautious and making sure not to cold start. On my way home from work, I was stopped at a red light, started to accelerate and heard and felt a POP that felt like the transmission slipping or something to that extent.
I noticed the car started to overheat. I pulled over, and being the rushing idiot that I am, I decided to open the radiator cap. I didn't hurt myself but coolant leaked everywhere and along with it were chunks of rust. I had a lot of trouble turning it over to get it home but ended up doing so and it didn't seem to run any worse, sans the overheating and cloud of coolant. I'm so nervous to take it to a mechanic and see the monetary damage. From the description, what I'll be in for? Did I damage it further by repeatedly trying to turn it over??

Just wondering if there's been any incident where the coolant in the SC430 is leaked into the gearbox at the radiator. I mean, these cars do have the transmission fluid running through the radiator, right? I've read that this occurs a lot on LS430 and many Mercedes models.
Would it be a good preventive measure to replace the radiator anyway? Or, is it ok to wait till there're signs of such leakage (if it doesn't usually begin as a major leak)?

My wifes 2002 gls has a coolant leak from the top radiator hose. I put a new hose on and two new clamps on the leaking end and it still leaks!! I have never seen anything like this and I am not sure how to stop it.

I have a 1996 Honda Accord 4 cyl. with 150 K miles. Had a coolant leak that the shop fixed. About 60 days later, same problem. I have to refill radiator every other day. What I noticed is a brown soft muck buildup at the radiator cap area. Also the car seems to run rough on and off. The underside of the oil cap is clean, no carmel color ( oil and coolant mixture) buildup.

I have serious drain now on the left side of the vehicle, and it appears to come from the radiator itself. Coolant consumption is approaching fuel consumption. Replace the radiator in a 2006- W12? Looking for some info on similar leaks and found them not originating from the radiator?

I drive a 1999 Toyota Avalon XLE and my radiator is leaking coolant from what looks like 2-3 spots. I replaced this radiator and the new one is leaking it is pooling very lightly on the top in the ridges of the radiator, and dripping on both sides below. I want to say it is the lines but i got new clamps and I even went as far as to spray silicon on the hard plastic piece the large softlines attach too so that inside under the clamps it would form a seal. the radiator I got is a Silla radiator if that matters

I got home tonight and smelled coolant. Looked under the car, coolant everywhere. I see the issue: a big hose (maybe 2" in diameter) has a tear in it and is spraying out coolant. I'm going to replace it, but once I do, how should I add coolant back into the radiator? Do I just pour it into the overflow?

1999 Honda CRV. Just took a 3-hour highway trip. Before trip I topped up coolant reservoir which was a little low, but radiator was full. I did notice some dried white spots on the front of valve cover and spark wires. Wasn't sure what it was, but now realize it was coolant residue. Probably only 1-2 cups were missing from the reservoir, so the leak had just started.
After 3 hour trip, checked engine compartment again. This time the reservoir was totally empty (radiator still full) and the engine was well sprayed with greenish coolant residue. The radiator was cool by the time I checked it, so the leak source wasn't obvious, but it looks to be coming from the seam where the plastic top meets the aluminum.
I will replace the radiator when I get home, but first have to drive the 3-hour return trip. Will it be OK as long as I start full of coolant and keep an eye on the temp gauge?

The last couple of days I thought I smelled antifreeze and I had to add about a pint of coolant to the reservoir. So I looked all around today and can't see anything leaking. Nothing on the floor. I suspected the water pump but looked pretty dry from what I could see. Thing is if its the pump, its still under warranty for a few months and 7,000 miles so want to find that pretty quick. Radiator is fairly new also from hitting a coon. Any tips? Not sure if a pressure test would detect a small or intermittent leak in the pump though.

I am in the middle of a several thousand mile road trip, and I am with family in Utah when this evening I noticed a puddle under my 6.0 Excursion.

The fluid does not smell like typical coolant, but from the location of the drip, I cant think of it being anything else.

I recently purchased a 1997 Volvo 850 and a week ago it began leaking coolant. Currently I am having to refill the coolant every three days.
I have attached two pics. One is a pic of where the coolant pools and the other is a pic of where I am pretty sure the coolant is leaking.
The leak appears to be coming from the connection point at the top driver side of the radiator. I know there is a hose on the same side at the bottom of the radiator directly below the one in the picture. At first I thought that was the source of the leak but later found it was just run off from the leak above.
Does this a common and fixable leak? Or if it is likely an expensive fix? Any other troubleshooting I can do on my end or do I need to take it to a dealer to find out what is going on?
