man i still cant figure out why my g35 is overheating . bled the air out the coolant system had the radiator checked and pressure tested replaced fans and thermostat still over heats ... maybe water pump ? anyone else have this problem . no white smoke or coolant in the oil ...

 

Could be a few things:

Are you leaking coolant? Try a block test to see if any combustion gases are in the cooling system. It's a 20 dollar test kit.

Clogged radiator? Not sure it could be the water pump unless the metal fins rusted away or somehow it's not circulating enough. It's driven by the timing chain and when mine went bad it was just the bearings making noise.

Could be a faulty cluster/gauge as well. Try using an IR thermometer on the radiator, hoses, etc...

 

i didnt try the block test ... and i was not leaking coolant . its going to a local shop in the morning im gonna see if they can find my problem . ill let ya know what it is if your interested . thank you for your reply !
