WHEN does it overheat???

Does it happen while driving, or when idling, or both

Is it visually overheating, or are you just going by gauge? Either way, what's the gauge at?

get a new radiator.... yours is clogged

i just had the radiator serviced and the guy said it was still good. im going by both the gauge and visually. the gauge is in the red and visually the water is boiling with it only being driven for a few minutes and the fan never turns off.

or dont believe me...

you need a new radiator... wanna test for yourself??? disconnect the upper and lower hoses, completely drain it. then stick a garden hose into the top radiator hose mount.... I'd be willing to bet that your flow will SUCK..


Better yet.. feel around ont he radiator for cold spots while the engine is warm/hot.

but don't believe me... Ive only been working on cars for YEARS
