Still losing coolant, no idea where??!!!
 

Allright i'm still losing coolant and I haven't the slightest idea where, holds 20 psi at the cap, runs fine, no white smoke at all, no visual leaks under the hood or car, holds fluid with the plugs out, is it an airbubble somewhere taking forever to find or what???????????

you sure your ast isn't leaking at the cap?

whats determining your losing coolant?

prolly the fact that e takes of the coolant cap and its not at the top

When you check the level in the overflow tank when the engine is cold is it consistent or is it dropping as well? If you take the filler cap off when the engine is cold the coolant level will drop due to the suction caused by the cooling system pulling coolant back in from the overflow tank when the engine cools down.

Remember that water/coolant expands and contracts when heated or cooled.

Ima keep an eye on it tomorrow, but I may just be freaking out and not loosing any coolant, cars has been getting warm and I just re-wired my stock fans to get maximum voltage and I think that may solve my hot issue and stop me from popping the cap all the time!!!

have you flushed the coolant system lately?

Also... do you have the factory AST?
