the radiator fan mate!! should have made that clearer. i tried different sensors lower and higher temp but nothing worked.the fan just kept running! i dont know what causes it. i was talking to jaystarr at the time and he said when the air-con was removed from a GT the fan stayed on but since i didnt have the Paseo wiring loom i couldnt bridge the 2 wires like i should have been able to do. it hasnt been running hotter at all because the fan was on constant but on the guage on the inside of the car (dash) the temerature needle stayed in the middle! hope that helps
