  Q: How to remove and replace a thermostat in a Chevrolet Camaro's cooling system?

  A: Disconnect the cable from the negative battery terminal. Drain the cooling system. If the coolant is relatively new and still in good condition, save it and reuse it. Remove the oil filler cap then lift the front engine cover up and off of the ball studs. Remove the two plastic retaining pins at the rear of the intake manifold and slide the rear cover off the manifold. Remove the coolant pipe front and rear fasteners then remove the coolant pipe-to-thermostat housing fasteners. Remove the coolant pipe from the thermostat housing. Remove the thermostat cover fasteners and lift off the cover. If the cover is stuck, tap it with a soft-face hammer to jar it loose. Be prepared for some coolant to spill as the O-ring seal is broken. If the thermostat is the type that is not attached to the cover, remove it from the housing, noting how it is installed. If the thermostat is the type that is attached to the cover, press down on the thermostat and rotate it until the tabs clear the locking ears on the housing. Remove the thermostat from the housing. If the thermostat lower housing must be removed, remove the coolant pipe-to-lower housing bolts then remove the housing bolts. For V8 engines, remove the drivebelts. Disconnect the radiator hose clamp from the thermostat housing and remove the hose. Remove the bolts and lift the thermostat housing off. It may be necessary to tap it with a soft-face hammer to break the gasket seal then remove the thermostat from the housing. Clean the sealing surfaces. Inspect the hoses, replacing them as necessary. For V6 engines with thermostat mounted in cover, depress the tabs on the sides of the thermostat and rotate the thermostat until the tabs are aligned with the ears on the housing. For all other models, install a new rubber seal on the thermostat, then install the thermostat in the housing, spring-end first. Install the thermostat housing cover and bolts, then tighten the bolts to the torque. On V6 models, install a new O-ring onto the coolant tube and insert the tube into the housing. Tighten the coolant tube bolts to the torque. Installation is the reverse of removal. Refill the cooling system. Start the engine and allow it to reach normal operating temperature, then check for leaks and proper thermostat operation.
