Thumbs down

so as some of you may remember i overhauled my cooling system last weekend. So I'm drinv to fedex to pick some stuff up because they can't find my place.... anyways I get there and computer says check coolant level.

So i try turning on the Heat to see if i get any as i heard it was a good test of the system if it blows hot air the thermostat is working... well no hot air warm yes hot no... warm because its 85 out. The temp gauge doesn't /hasn't made it past the half way point.

I get home, pop the hood coolant looks low. I open it (i know i shouldn't when the eninge is hot and fluid spills out the top of it.) which brings me here...

Ideas? re replace thermostat? take it out and put it back once things cool down?

Did you rev the engine while you put the coolant in with the heat on high? You probably just have an air bubble in the heater core. Oh and it sounds stupid, but did you turn the little dial on the middle vent to the red? I assume you did

would this explain fluid flowing when opened?

yep the little white line was as far to the red as it could get and the temp dials both red too and fan was turned on high.... nothin...

so wait for it to cool down and see what she takes?

Start it up open the cap, and the little air screw. Then poor coolant in while somebody has the heat on high and revs the engine. If it were a bad thermostat you'd probably have more problems or your needle will take FOREVER to get to the middle.

Thanks Kevin I will try that once my girl friend gets home....

it also takes the car for damn ever to cool down. I start the car 3 hours later and temp is at mid point.
