How to Replace the Thermostat on a '94 Camaro

The 1994 Camaro saw many improvements, such as the first convertible model for the V-6 and Z28 engine models and several fuel delivery changes to improve gas mileage. One thing that did not change was the mechanical thermostat that controls the amount of coolant that flows through the engine to control the operating temperature of the Camaro. This means you must pay attention to the thermostat when the engine starts to reach higher temperatures. Thermostat replacement will ensure your Camaro stays in top condition.

Things You'll Need

  • Flat-head screwdriver
  • 10 millimeter wrench
  • 1994 Camaro thermostat
  • 1994 Camaro thermostat gasket
  • Trace the radiator hose that extends from the top of the radiator to the engine of the Camaro. The cover that the radiator hose connects to is called the thermostat cover, and the thermostat is under that cover. Remove the radiator hose from the thermostat cover by removing the band clamp with a flat-head screwdriver. Pull the hose from the cover and hold the hose up to drain the radiator fluid back into the radiator.

  • With a wrench, remove the two 10 millimeter bolts that hold the thermostat cover on the intake manifold. Pull the thermostat cover off the intake manifold and inspect it for any cracks. If cracks are present, a new thermostat cover must be used to prevent radiator fluid from leaking.

  • Pull the thermostat from the intake manifold with your fingers and remove the old thermostat gasket from the area where the thermostat cover was removed. Discard both; they will not be used again.

  • Place the new thermostat into the intake manifold with the end that is marked "top" facing out of the intake manifold.

  • Place a new thermostat gasket onto the top of the intake manifold with the holes cut out in the gasket lined up with the holes drilled into the intake manifold for the thermostat cover bolts.

  • Bolt the thermostat cover back onto the intake manifold using the original bolts. Avoid overtightening the bolts to prevent cracking the thermostat cover.

  • Reattach the radiator hose to the thermostat cover and tighten the clamp that holds the hose into place with a flat-head screwdriver.
