2005 Chevrolet Classic Coolant Temperature Sensors

To avoid being burned, do not remove the Radiator Cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if the radiator cap or surge tank cap is removed while the engine and radiator are still hot.

You should remove the exhaust manifold before servicing the Water Pump.

Remove the exhaust manifold, drain the cooling system, remove the Thermostat housing to the water pump feed pipe, and remove the thermostat.
