My coolant light had come on for a little while right after starting the car a couple times, so this morning I checked it and it was a little low. I had a hard time figuring out exactly how much to add because it was hard to read, but was pretty sure I got it right to the full line, if anything maybe a slight bit under...

I went back out about 30 minutes later and there was a pretty good size puddle of something around the front passenger side tire, and I'm pretty positive it was coolant, so I cranked the car and moved it back 10 feet, then left it running while I went and checked out the puddle. I let the car sit running for about 5 minutes so I could see how big of a puddle it made while it was sitting there, but when I moved it again there wasn't a drop of anything under it. So in other words, being turned off for 30 minutes made a pretty good size puddle, but running for 5 made nothing... It is possible that the puddle was there before I added coolant, but I'm pretty sure I would have noticed it.

So my question, if I were to have a small hole in one of my hoses or something, would it be likely to leak while the car isn't on, but then not leak while it is running because the coolant is moving under pressure? I would think it is probably a leak in a hose rather than in the tank itself based on where the puddle was...



Any input? Thanks

Sounds like your hoses are worn. Most likely your upper radiator hose.

You were right. Finally found the source of the leak today and it was just a small hole in the radiator hose..... Good call!

Did you have to take anything apart to be able to get a visual in there?

Nah, I didn't have to take anything out but I did have to run by a shop and use their lift... It was impossible to see from the top, and it was pretty hidden from the bottom too, so just jacking it up and crawling under there with a flashlight didn't help much either cause I didn't really have room to look around good enough to find the hole. Once I lifted it it wasn't too hard to spot though....

Are you having a similar problem or something?

ArXate

Yes, I'm having the same problem. Still need to diagnose like you did to see if the leaking stops when my engine is on (and crossing my fingers that that's the case).

When my car was at the dealership for an oil change and they lifted it up, they let me go look underneath. We couldn't tell anything about where the coolant dripping was specifically coming from other than from the passenger side. They said I'd have to take out the undertray.

However, I've heard that you can take out the battery and battery tray to get a look in there.

BTW, how many hoses are there to the cooling system circuit?

Mazurfer

3 major ones. ( I think!)

I'm not positive, but 3 major ones sounds right to me too..... Yeah, I got lucky that mine happened to be in a spot that was visible without taking anything out. I was able to spot it looking through the opening in the undertray that is right under the waterpump. See if you can find an opening that gives you a decent view, find the spot that it is dripping out of the bottom from, and follow the trail of liquid up as far as you can....

If you can't find it that way then yeah taking out the battery and battery tray should give you a pretty good view of that whole area

Kinda the same problem here. Today I went to get an oil change and the dealer informed me that there is a small coolant leak. Not at all what I extecpeted. Well he stated that I would need a new Upper and lower radiator hose, Thermolstat plus gasket. All for a whopping $400.00!! Bullshit! My car does not overheat just for ya'll to know. I found both hoses and thermolstat for $60. So I need a few hints. Where extactly is the thermolstat located? Just to be sure. Do I have to drain the radiator first in order to replace the hoses and thermolstat? Here is my big question: The dealer stated GASKET. Does anybody know what he means? What Gasket?

If you don't know where the thermostat is and if you have to drain the radiator or not I wouldn't do this job until you learn a little more. But just so you know.

Draining the radiator before replacing the hoses will keep you from making a huge mess.

The thermostat is found where the engine block and upper hose meet.

He is talking about the water pump gasket.
