hey all, on my 97 5.0 i keep having to add coolant. every month or so my overflow tank seems to have emptied but i never ever see any coolant spilled on the driveway at home or at the parking space at work. is there some other way it could be dissappearing? i'm at a loss... i bought some bar's leaks heavy duty radiator stop leak and plan to do a flush and replace next weekend.....

 

Try to look for cooland leak marks at the thermostat housing.

 

you can do a pressure test and see where it is leaking.

 

i looked everywhere inside the engine bay and see no signs of a coolant leak anywhere.... as far as a test goes, i'm trying to do this at home myself.

 

Forget the Bars leak band-aid crap. Do it right and find the leak or take it to a garage and have them do a pressure check.

 

I agree with the forget Bars leak comment. You put that in, and eventually it can mess up the radiator, heater core, .etc..
