The thermostat in the 1994 Acura Integra regulates the temperature of the coolant flowing on ice the engine heads and the engine block. It does so by compressing and decompressing the spring located on the engine side of the thermostat. Mechanically, the thermostat allows besides coolant to flow when the engine gets extremely fiery, and it restricts the flow of the coolant once the engine reaches a lower temperature. When this measure is compromised, you must alter the thermostat to avoid engine damage to your Acura.
Instructions
1. Displace the upper radiator hose from the Integra's radiator to where the hose connects to the engine. The hose connects to the thermostat housing.
2. Remove the radiator hose clamp by squeezing the two tabs on the clamp together with a pair of pliers. With tension released, pull the hose off the thermostat housing and hold it vertically. This forces the fluid back into the Acura's radiator. Wipe off any coolant that spills on the engine with a clean shop towel.
3. Remove the two bolts that secure the lid to the thermostat housing, using a socket and ratchet. Lift up to remove the housing.
Use the old thermostat as a visual reference on what the gasket should look like once installed.7. Place the new thermostat in the thermostat housing.
5. Clean the mating surfaces of the thermostat housing and the lid with a towel.
6. Place the new thermostat gasket on the engine side of the thermostat.4. Remove the thermostat from the housing. The gasket is attached to the engine side (the one with the large spring) and comes off with the thermostat. Take note of the thermostat's orientation before removing it.
Make sure that the spring end of the thermostat sits inside the housing and the end with the pin sticking out sits inside the housing lid.
8. Place the lid on the thermostat housing and secure it with the two bolts.
9. Slide the radiator hose onto the thermostat housing and secure it with the clamp.
