i think there is definitely an issue with the temp sensor. i haven't had my truck that long, no real road trips yet, but the temp routinely reads 8-13 degrees F above what it actually is outside. i just got rid of my 98 explorer and it's temp guage was right on all the time. i don't expect the guage to be that accurate, but more than 10 degrees off routinely? seems a bit excessive. anybody else with this issue?
