The 1984 Chevrolet Corvette comes equipped with the 350 cubic inch and fuel injected engine. This engine uses multiple sensors to send data back to the engine control module. The engine control module or brain box determines the mixture of fuel and air for the engine. A coolant temperature sensor is a key component providing data back to the brain box. When this sensor fails an incorrect mixture will be supplied to the engine, resulting in failure to run or poor performance.
Tools Used : Screwdriver, Metric wrenches, Ratchet, 21 mm deep well socket, Torque wrench, Antifreeze fluid
Install Temperature Coolant Sensor
Remove the air intake duct by loosening the clamp at the throttle body with a flat blade screwdriver. Loosen the second clamp at other end of the duct and pull the duct away from the engine to remove.
Remove the air control bracket at the front of the intake manifold. Use a 10 mm metric wrench to remove the two lots holding the bracket in place. Pull the bracket towards the front of the car to gain access to the coolant temperature sensor.
Disconnect the electrical connector attached to the coolant temperature sensor by gently prying the lock portion of the connector up. Slide the connector from the coolant temperature sensor.
Loosen and remove the coolant temperature sensor with a 21mm socket and ratchet.
Insert the new coolant temperature sensor into the intake manifold. Tighten the sensor to 108 pounds with a torque wrench.
Reattach the electrical connector using gentle pressure until it locks into position.
Reattach the air intake control valve by inserting the two bolts into the original position. Tighten each of the bolts with the 10 mm wrench.
Slide the air duct over the throttle body and tighten the clamp to hold it in position. Reattach the bottom of the air duct to the air filter enclosure and tighten the clamp to keep it in place.
Check the coolant level and add antifreeze to return it to the full level.
