GQ Tb42 Heating up???

Hey guys, just wondering if anyone has any ideas on my heating up problem??? She runs fine at a temp below the half way mark but if I am out in the scrub and not doing much speed she warms up to almost the three quarter mark...this is only when I have the air-con running, I then have to turn the a/c off to let it cool down again, it also seems to lose power and start missing and carrying on when it warms up...I have just removed the thermostat...will this help keep it cooler and will it harm my motor if I dont put another thermostat back in it???

Cheers Jays

How hot is it where you are mate.... does it climb further then 3/4 ??

I'm in Rockhampton mate, bloody hot and humid at the moment and no it doesn't go any higher than 3/4...probably doesn't even get that high and it's only when I'm doing low speeds under labour...cools down pretty quick when the speed picks up again...

Might be a cooling fan/ thermal fan issue or could just be over working the motor while the air con is on.

Three quarter mark with air con and low speed...hmmm, not too bad but could be a bit better.
My air con does not work but I do get temps above the half mark which does not worry me. If it gets towards the high mark then I would take some action.

Something you could look at is flushing your rad, changing yoyr cap and the thermostat to start with.

I think its not so much a problem really... better than mine...;)

Ok...I have flushed my radiator and removed the thermostat all together...was just wondering what the missing and carrying on is at that higher temp...haven't taken it for a run since I removed the thermostat so I guess I'll see what happens...

Missed the bit about the farting and carrying on... when were the valve clearances last done???

Is the car petrol only... carb fuel injected

I have only owned the car since xmas and I haven't done them...don't know how to lol...cant tell you when they were done before I owned it...

Put a rag over the exhaust with the car running and give it a rev.. if the rag wants to suck up the pipe then you need clearances done....
