  Q: How to test the operation of a thermostat for Chevrolet El Camino?

  A: To test the thermostat's operation, it should be removed from the engine. If one doubts about the thermostat, then it is most likely that it is cheaper to purchase a new one since they are not expensive. Before you can start testing, remove the thermostat. Examine if there is excessive corrosion or damage on the thermostat. Replace with a new thermostat if either of these conditions exists. Place in hot water 25 degrees above the temperature stamped on the thermostat. For example, since almost all Chevrolet V8 and V6 engines use 195-degree thermostats, the water temperature will be around 220. The valve must be completely open when submerged in this hot water which has been stirred vigorously. After that, unbend a piece of wire and draw out its thermostat before immersing it into water that is 10 degrees below what appears on its body. In most cases this cooler water temperature should be 185 degrees. This means that at this particular temperature, the valve should close fully. Reinstall if OK or purchase a new thermo-stat of equal rating to install your thermo-stat in case it checks out OK.

  Q: How do you remove the thermostat from an engine for Chevrolet El Camino?

  A: A thermostatic element inside a housing on the engine actuates the thermostat, which is a restriction valve. It opens and closes to regulate coolant flow at predetermined temperatures, thereby enabling either engine warm-up or cooling. Disconnect the negative battery cable and remove the air cleaner so you can get at the thermostat with ease. Find a suitable container and drain the coolant into it. Remove the thermostat housing bolts and disconnect upper Radiator hose from it. At this point, lift up the housing hence exposing the thermostat while considering where it was located previously for later replacement. Clean both surfaces of gaskets on housing and engine body. Insert RTV or equivalent sealer and put the thermostat onto its space properly. With new gasket, fit housing on with correct tightening of bolts. If necessary, re-attach alternator brace and TVS switch plus vacuum hoses as well. Make sure that upper radiator hose is securely attached. Reconnect negative battery cable then use right coolant mixture to fill radiator. Start engine; if necessary pour more coolant into system hereafter. Finally put back radiator cap matching arrows on it with overflow hose.
