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.
