I notice that I smell coolant every once in a while, seems to be coming from the passenger side, I was thinking it was the coolant overflow bottle. I have never seen a leak, my coolant light comes on every now and then but if I turn the car off then on it is gone, my coolant level is good. I had one of my techs here at work pressurize my system and NADA!!!!!! NO flipping leaks. I have checked and rechecked my lines. I also checked my radiator for oil and my oil for antifreeze, so no blown head gasket, my car never gets above 180. IS there something I am missing, or are the cooling system on the ls1's just really high pressure and my overflow just getting full and then pressure goes down and sucks it back in???

what about a bad sensor for the coolant level? I would replace that

temp isn't the problem, its the fact that I smell coolant. My temp is right on, the car has an slp thermostic switch so the fan kicks on earlier.

Checked there. It's wierd I havn't had to add any. Its like a depressurization in the system. I am very meticulious about my cars, if there is any leak or sign of one it is fixed right away. I just can't seem to find one!!!!!!!!!!! I am just curious if I am the only one who has the problem!!! Is there any small coolant lines on them around the radiator area that I might be missing???

only thing I can think is to trace the line down to your radiator. maybe a hose clamp shifted or something. definately weird. good luck!

now that I havn't checked!!!! i am going to have my tech pressurize the system again and see if a small leak is coming from any of them.

When doing the pressure test is it holding all the pressure. Just because you don't see a leak doesn't mean there isn't one. Sometimes they can be tough to spot.

pressure is staying in the green, it has been on my system for over an 1hr, I am going to see if it holds for another 1hr.

i am willing to bet it has something to do with your hose clamps. check it out and let us know what you find. I am curious...

I'm betting that's what's wrong with mine. Actually I know. haha When I'm sitting in traffic, my low coolant light comes on. I can fill the overflow up and step back and watch the water come dripping out on the ground.

i had the same problem still have it really just dont have the low coolent sensor anymore i replaced my overflow tank and it still does it but never gets hot since my fans kick on at 160 due to part of my tune

it was such a small hole, it was the size of a pen head. I took a butane torch and closed it right up no leaks even after a pressure test. It is not any fun taking the damn thing out though. I already had the please of replacing the wiper motor!!!!!!! My arms are still battle scared from it.
