I replaced my water pump and my rad fan (fan was definitely seized) and now it's still overheating sometimes. Yesterday at idle the fan wasn't turning, so I revved it to 2000rpm and the fan kicked in. It cooled down immediately.
Any ideas? Thanks. |

Get a volt meter and check your sensors, the thermo switch might be a bit buggered from the seized fan.
Maybe the thermostat is wack too but check and see if the sensors are putting out the right resistance and check how many volts the fan is getting and see when it does and trace it's wires from there to the sensors. |

is it an electric fan on that thing? Or a thermostatic clutch fan attached to the water pump?
Also could be you have an air bubble in your cooling system.. on my old car (87 fifth) it had a nasty habit of getting an air bubble right below the Tstat when I drains and filled the coolant... and as such no hot coolant to heat the open the tstat |

I had the thermostat replaced in the fall, not that it matters but it's still fairly new...
It's an electric fan..
How would you find if there's a bubble in the coolant?
Thanks. |

| bubble.. I dunno how to tell with out draining a bit and looking., i eventually worked it out by squeezing my upper rad hose, but my T-stat had a jiggle valve to let the air work it's way through.. |

| So, I figured out what happened. I put a new line on that needed to be replaced, and when I did that I put some new coolant in just to see it come pouring out of the radiator through the fan assembly. The clip for the fan was out a little bit too far and put a nice hole into the rad..I should have checked it before I started driving the car :mad: |
