Hi guys,
I've got an R34GTR and recently had my clutch replaced since the clutch replacement or recently after I've noticed my daily driving temps have significanlty increased. To keep temp level at close to 100 I have the car in sixth gear and 2000rpm anything over this will cause water temps to increase. I live in northern aus so its hot all day everday but this was never a problem before. Even a spirited drive wouldn't bring the the tempts upto 100, maybe close 95 or 96 before I'd slow it down and go back to normal driving to bring the temp down.
For some reason my overflow bottle didn't have a lid/cap so I bought one yesterday and it was $16.30 for a milk carton lid from Nissan, so I put it on and filled it with coolant.
Prior to this I'd flushed the radiator by removing the bottom rad hose putting a hose in the top of the rad and just idling the car which did absolutely nothing, mind you at that time the overflow tank was empty and and there was no lid on it.
I can drive normally and the car doesn't go up to ridiculous temps but it still goes quite high like into the 90's in no time at all, so I'm always keeping an eye on temps, keeping revs low etc.
My next thought was to check the thermostat is stuck closed or partially closed. I thought this was changed in service I did about 20K ago, along with the water pump, did 100k service very early.
Thoughts???
