Coolant Temperature Sensor:

3. Connect a suitable timing light to the number one cylinder, (refer to manufacturer's instructions for correct procedures).
4. Start the engine, the radiator fan and check engine light should come on. Point the timing light at the timing marks on the front crank shaft pulley.
5. If the timing is within specifications (12 +/-2 BTDC) no adjustment is necessary. If the timing is outside of specifications loosen the distributor hold down bolt enough to enable the distributor to be turned. Turn the distributor until the timing mark is within specifications and tighten the hold down bolt.
6. Turn the engine OFF, connect the coolant sensor and disconnect the timing light. Erase the fault codes set by the timing procedure.
