Ok from the start....
Ive got a Greddy Informeter which tells me the water temp, 02 sensor voltage etc in the car and over the last month or so ive noticed the water temp goin up, i think its even hit 100 degrees!
Anyway, i babied it to the mechanic and basically flushed out the coolant and replaced the thermostat.
Got it back and still running a bit hot. Mind you the standard gauge was sitting on normal.
Decided to take it back and do a 100K service which included the water pump, belts, spark lugs etc...Still running hot when i got it back, i think i even saw it go past 100 and the standard gauge went up about 10mm! Obviously the Oil temp went up also, it hits about 100-110.
There are no coolant leaks, no discloured or bubbley coolant so i dont think its a headgasket, ive have replaced the Coolant Temp Sensor on top of the block, bled the system again and again.
I notice when i put the foot down the temp will rise, but steady driving it will sit on about 96 - 100.
I put the heater on flat out to cool the engie down and that seems to work.
PLEASE HELP DIAGNOSE! searching hasnt helped much.
Could it be that the fan belt is a bit loose and not working to its full potential cos i have a hunch its loose??
I friggin pamper this car and never miss a service.
