My coolant overflow is filling up and overflowing. The mechanic at the dealership says I have a blown head gasket. My oil isn't milky looking though. I'm going to try some K&W head gasket repair. It says to check the spark plugs to see which cylinder is leaking. Wonder what signs I should look for?

 

if your looking at the plugs the one that is leaking will be really white. i have had good luck with this stuff http://barsproducts.com/catalog/view...asket-fix-1111 its lasted several months on a truck that was blown pretty bad

 

Dont EVER use "repair" fluids for fixing a coolant problem. It leads to MAJOR problems down the road. Like clogging coolant passages.

Your head gaskets ARE bad. Had the exact thing happen to me. Fix it right now so you dont have to deal with the problems down the road.

 

I hear what you are saying but this stuff does not remain in the system. It either works or it doesn't as you flush the system after it does it's thing. You remove the thermostat before you use the product. I have checked four of the plugs and one did have a bit of rust on the threads and the ceramic base of the electrode had a reddish tint to it.

 

x2 do it right the first time or your going to have problems down the road. I mean the stop leak is going to do what it was designed to do, BLOCK HOLES and PASSAGES. Whether you flush the system after using it or not, the stuff has already built up inside the passage for the cooling system and is now blocking where you want coolant to flow.
