Installation of Thermostat

I did this as preventive maintainance at 90K miles. One rule is always put the thermostat is a pan of water and heat it on the stove. Watch to make sure it opens. If you've ever installed a new thermostat that was defective, you know why the pan of hot water is simple insurance.

1.		Decided to replace the thermostat when I was doing a couple other things so the intake elbow is already out of the way.
2.		This shows the thermostat housing with the old thermostat removed.
3.		This shows the new 180 degree thermostat in the housing. Part number GM 12555290, AC Delco 131-100.
