:shrug: I got a 90 Integ and when I turn my car off, the fan will come on and stay on the whole night until it completely drains the battery and I got to push start it in the morning. Sometimes when I play with the ignition, it will stop and other times it will stop for a moment and come back on like a hour later. If somebody knows how to fix this problem, please let me know!:bang:
take and hook the fan up to a toggle switch that would be probaly the easiest
it is most likely your thermo switch, or it could be a bad relay, or ur themometer itself. my problem was the thermo-switch, just ordered a new one and will install it tomorrow. hopefully. hope this help, best of luck to you.
remove your coolant temp switch and test it.
the procedures are detailed in the helm manual.
