Hi! I have a 1996 Altima GXE that recently got a big crack in the top of the radiator. I tried to seal the crack with some radiator epoxy to no avail, and right after steam blew through the epoxy, the check engine light went on and the heat sensor went up up up at idle. I nursed the car a few blocks home and haven't driven since. I checked the diagnostic trouble code and came up with - Engine coolant Temperature sensor function (voltage to ECM low/impractical even after engine has been on for a while) - which I guess implicates either the thermostat or engine coolant temperature sensor, assuming the coolant hadn't run dry. To my question, when I take it in to the mechanic tomorrow, I should expect to replace the radiator, thermostat, and possible the ECT sensor, right? And could this be indicitave of a bigger problem, such as a failed water pump? Any suggestions would be helpful, as I just bought this car, and I am finding a new mechanic for the job. This is all new to me, as I have only owned aircooled VW's in the past! Thanks so much,
Mike
