What should actual coolant temp be?
Hoping someone here will know the answer to this. My 1989 E-350 351 v8 seems to read quite hot on the temp guage, perhaps just over 3/4 of the way to the H on average. The difference between the lowest and highest average reading on the guage is minimal. Could the guage be calibrated incorrectly? should I check the coolant temp when hot and if so what temp is too hot.
Just got this vehicle so I don't know much history on it.
Thanks in advance, MarkT
