HELP!!!!!!! OVERHEATING
Wednesday, April 27, 2005 5:58 AM
I have flushed my coolant, checked my Rad, and wired up a fan relay switch. I now keep my fan on almost all the time, and my engine will still begin to over heat at times.

Can this be the oxygen sensor?. i am about to replace it, but if that does not work, does anyone have any ideas????

Thanks!, Mitch

Sounds like your waterpump....

Are you also seeing coolant leaking from underneath your car?

No, i have not noticed any coolant leaking, but i will start to keep my eye out now.

The only other issue about the water pump, is that my engine will stay below normal with my fan on, At idle there is no issues, It only begins to heat up when i am driving it hard, or over 140 km/h .

What sort of problems would i see from water pump?. wouldnt it always be over heating?

From my personal experience, yes the car would always be running hot....but I also noticed a few small spots of coolant underneath my car. I was proactive and got it done, and it turned out my judgement was right.

As for "the sorts" of problems, and other info on the waterpump, Im not really in any position to comment on that since Im not a mechanic. Your best bet is to do a search through this website, as Im sure there is a tonne of info on the waterpump for 3rd gens.

Could be a wonky thermostat, try changing it along with the gasket, only costs like $25 for the thermostat and $5 for the gasket, cheap troubleshooting step

A thermostat that is stuck closed will cause overheating. It doesn't allow coolant to flow from the engine to the radiator where the actual cooling is done.

A bad head gasket could also cause this problem, because heat from the combustion cycle will enter the coolant system, heating it up moreso than usual.

Have those two things checked.
