I have a 1988 ford tempo. runs good till it reaches running temp.

Question

At running temp. car dies and wont start until it cools off, then it runs fine til it heats back up and it dies again. What could be the cause? I changed the coil.The water circulates good.

Answer 1

Mmm .... air temperature sensor maybe? Or even Lambda sensor ... altho with Lambda sensor I'd expect you'd have a performance issue now and again. If the exhaust gases smell too strong, like unburnt fuel then that could be an indication of a Lambda problem.

Good luck!!

Answer 2

the thermostat could be sticking or the fan doesn't turn on when it should P.Sif u run it too hot you'll mess up the heads and after that you'll break the block then ur S.O. L.

Answer 3

coolant temperature switch
