My cavalier is leaking antifreeze. It's not coming from the water pump or any of the hoses. Any idea where it could be coming from? Manual says to check the radiator core or header tank. I think I know where the radiator core is, but where is the header tank..if it has one. I did notice some build up of antifreeze underneath the fly wheel, which drives the ac, water pump, etc. Can anyone help? I have a 93' cavalier 2.2 ohv.

hi i actually have the same problem only with a 94 cavalier 2.2, its leaking antifreeze at this little elbow looking thing, right infront of the passenger side firewall,(dirrectly below another line i think goes to the heater core? i dont know) not connected to the engine, but its still taking all the antifreeze out of the reserve tank, what the heck is gonig on? i know thats a little bit confusing but somoene might understtand. only other thing i noticed is my radiator is still full to the top...?

Proably best bet is to put coolant teaster @ radaitor and then llook for the leak or add coolant dye and then look for leak with dye detector .....

hey there, i have a 94 cavalier, and had similar probs, u might wanna get the head gasket seal looked at asap, cuz ours or aluminum heads and they will go quicky if not looked at, and they can be plained but not much
