hmm coolant system pressurising. I would do a CO2 head gasket test.

1 10" thermo fan? is that all. i was running 2 10" thermos and was still overheating in peak hour traffic. switched to a big 16" single and didn't have a problem after that.

also have you got the fan running the right way?

yea pressure test was next, and i brought 2 10" but only one fit with the big radiator it hit the powersteer hose. and it run fine for weeks and i drive home from briss everyday to brownsplains, but would like to go biger

weres ur shop 07 33 shouldl be close to me

it may have run fine for weeks until you put the frount mount on. which adds abit of restriction to the airflow.

but u would think it would cool down wen doin 100 cruizin cause u dont need the thermo then.

You need air flowing through the radiator for it to keep the system cool. My experience is that thermos don't work on 32s. Air simply hits IC and flows down under the car. At least with the factory-fitted engine fan, it creates a low pressure area inside the engine bay, and air has to go through the radiator.

It coud also be that the radiator is too thick, and you can't cool the rear side of the fins.

Have you confirmed that the water pump is still pumping water?

Replace your thermostat with a new one, it could be stuffed. Check your coolant mixtures too. Do a high pressure flush of the cooling system.

Hopefully this helps.
