That is NOT a good idea and I will try to explain why. The computer has to see 195 degrees to get the proper air to fuel ratio. If it is running cooler the computer sees that and keeps the mixture Rich. While running rich you are paying $4.00 a gallon for gas. If the cooling system is the problem THEN fix it.

Changing the thermostat on a 2002 Chevrolet 4.8 liter engine is simple to do. First, follow the upper radiator hose to the thermostat. Then drain the radiator hose. After the hose is drained, remove the clamps and bolts holding the thermostat housing in place. Then remove the old thermostat and replace with a new one.

It is in the thermostat housing at the end of the top radiator hose on the engine side.
