overheating...

dhaines · 07-11-2007, 12:43 PM

HI all, im new to tts. been used to working on toyotas and various english cars.

the other day on the highway it started getting hot, by the time I got home it had just tripped the warning light. Now it gets hot just taking short grocery jonts.

I dont think my fans are coming on. Is there a way to manually trip them to come on ?

Im trying to rule out the water pump as I dont really feel like changing it just yet, but Ive read that they are weak and fail regularly. but how can I test the pump?

Check the flow of returning coolant at the header tank or lack of flow.

I figured out that the fans do work. Turning on the ac turns on the fans, so i guess they are ok. I will pop the hose off and check to see how much coolant is getting circulated..
if I dont get any flow im assuming that the pump has failed or the tstat is stuck closed?
