1995 Geo Prizm Q&A
1995 Geo Prizm Question: if my catalytic converter is clogged (not totally ) would this cause it to....
would this cause it to overheat and blow up my radiator? Or, could it be i have a blown head gasket? at first i thought it was the thermostat...but i took it out and it still blew up another radiator. i blew up a third radiator today! WTF I'm baffled. I put a new radiator in it and ten miles later it just blew up around the radiator cap. - bettybbboop
Blown headgasket! Get a block check done to be sure... - Hal...
Got to be compression from the engine going into the cooling system. I say head/gasket problem!! Just how hot did it get? Quit running? - pushrod
I had a nissan pickup that had a clogged cat close to the engine and it caused the head to warp, cracked the valve guides, and spew coolant quick. repair was $1,500. If you know the cat is mostly clogged, change it out. - lightsaber
