COOLING, HEATING AND AIR CONDITIONING SYSTEMS
COOLANT TEMPERATURE SENDING UNIT | CHECK AND REPLACEMENT (Refer to illustration 9.3)
SUSPENSION AND STEERING SYSTEMS
WARNING: The engine must be completely cool before removing the sending unit.
- If the coolant temperature gauge is inoperative, check the fuses first (see Chapter 12).
- If the temperature indicator shows excessive temperature after running a while, see the Troubleshooting Section in the front of the manual.
- If the temperature gauge indicates Hot shortly after the engine is started cold, disconnect the wire at the coolant temperature sending unit (see illustration). If the gauge reading drops, replace the sending unit. If the reading remains high, the wire to the gauge may be shorted to ground or the gauge is faulty.
- If the coolant temperature gauge fails to indicate after the engine has been warmed up (approximately 10 minutes) and the fuses checked out okay, shut off the engine. Disconnect the wire at the sending unit and using a jumper wire, connect it to a clean ground on the engine. Turn on the ignition without starting the engine. If the gauge now indicates Hot, replace the sending unit.
- If the gauge still does not work, the circuit may be open or the gauge may be faulty. See Chapter 12 for additional information.
- With the engine completely cool, remove the cap from the radiator to release any pressure, then reinstall the cap. This reduces coolant loss during sending unit replacement.
- Disconnect the wiring harness from the sending unit.
- Prepare the new sending unit for installation by applying a light coat of sealant to the threads.
- Unscrew the sending unit from the engine and quickly install the new one to prevent coolant loss.
- Tighten the sending unit securely and connect the wiring harness.
- Refill the cooling system and run the engine. Check for leaks and proper gauge operation.
STABILIZER BAR (REAR) | REMOVAL AND INSTALLATION
(Refer to illustration 9.2)
- Raise the vehicle and support it securely on jackstands.
- Disconnect the stabilizer bar link from the suspension control arm (see illustration). Note the order in which the bushings and spacers are arranged.
- Remove the stabilizer bar bracket-to-body bolts, remove the brackets from the body and remove the bar from the vehicle.
- Check the bracket bushings for cracking, hardness or general deterioration. Also check the link bushings for wear. Clean the areas where the bushings ride with a wire brush. Replace worn parts as necessary.
- Installation is the reverse of removal. A light coat of vegetable oil will ease installation of the bushings and U-brackets (don't use petroleum-based lubricants or brake fluid - they will lead to premature failure of the bushing).
