Re: '90 V8Q: Hot coolant temp!
You thermostat might be stuck close or you fan is not kicking in or could
be both. If the fan is not kicking in, you probably want to check the fan
switch then check the fan itself. I used to have a 85' 5000s which had
the same problem which turned out to be a stuck thermostat.
