- Sun Feb 17, 2008 6:15 pm #42631 My sedan has been using coolant since i bought it. it doesn;t leak any coolant any where. the head gasket is good to the best of my knowledge. but the coolant doesn't seem to be circulating at all when i heat up the engine and check the radiator. i get good heat some times but it might take longer than usual. the fan never runs allthough the relay, fuses and plugs are fine. the thermostat was supposedly replaced. what could it be????????

Do you ever pop your hood after driving and find the overflow tank is full?
Does your coolant have a fine oily like film on the surface?

like this:

Those things would indicate a leaking/blown headgasket. You won't always have the white smoke from the tail pipe, but it will still consume coolant.

- Mon Feb 18, 2008 5:00 am #42724 a bit filmy yes, and when i take the cap of the radiator coolant poors into the over flow and air comes out of the radiator, the temp did go above half last night, but why would the heat be so intermitant as is the smell. and why are the fans running?

i'm betting on your head gasket then.

leaking or blown HG can push air from the combustion chamber into the coolant passage, creating high pressure and forcing the coolant out through the overflow. then you get air pockets in the coolant system which can cause overheating at times. the film comes from oil/fuel entering the coolant passage from the combustion chamber.
I had this and my HG was cracked between #2 and #3 cyls.

Another time the HG was not cracked at all and it was happening, probably not properly torqued :?

the fans are running because your ECU is telling them to turn on because the temp is overheating, although when I had similar problems, the fan would only kick on for a min or so.

those are the exact things that i have :(

along with sputtering and misfiring when fired up sometimes, which is the engine trying to clear out the coolant and burn it off

- Wed Feb 20, 2008 7:39 pm #43172 if it's not overheating then it is very minor. maybe leaking somewhere else like the thermostat or a seal someplace. I'd keep an eye on your coolant level until the problem gets worse and you can pin point it.

- Wed Feb 20, 2008 8:48 pm #43178 The gasket set i ordered includes almost every gasket imaginable. so i'm going to do all of the water gaskets, the valve cover gasket/ sparkplug tube gaskets. intake/exaust manifold and the head gasket. the coolant just doesn't seem to be flowing and the hoses seem to not have alot of coolant in them and the coolant in the radiator and lower hose never seems to get hot so idk what the problem is but i already got the gaskets coming so we will see. IS a graphite head gasket any good? let me know what you guys think.
