===============================================
I would check out the thermostat too. You might need some hose clamps for
that. I would also
change out my coolant and make sure that the radiator gets bled out at 2000
rpm. Test the fan.
Test the fan switch. I paid the $15 for the new switch just as insurance.
You will pay less if you mail order. Clean the grounds. Make sure that the
oil level is about 1/4 above minimum!
We don't need drivers, just a good nurse.
