Hi guys -
I was about to change out my thermostat...engine temp gauge moves around quite a bit and I really only get good cabin-heat if I am driving up a hill.
But now, I believe my water pump has gone out too...funny squealing noise. Also noticed the radiator fan isn't turning anymore...
So I was curious, if I am replacing the water pump and thermostat (and a fan motor), should I replace anything else while I'm in there? My timing belt looks fine and was done 35k miles ago. Any advice would be greatly appreciated
Cheers,
Courtney
If yours is a diesel Jeep; your signature does not say, the water pump is driven by the cam timing belt, not the serpentine belt that drives the radiator fan.
Check radiator fan hub bearing, there have been a few of them that have failed.
Or could be the belt tensioner or one of the idler pulleys for the fan belt?
As to the squealing noise; you can remove the radiator fan serpentine belt completely, start engine and see if noise is gone.
If it still makes the noise, then problem is either the water pump, or the cambelt tensioner, or one of the cambelt idler pulleys and will require pulling the cambelt cover to locate.
