Coolant Level Sensor (GM 3000–D)

The sensor is located on the degassing box, which is on the upper left end of the engine. It energizes a red warn ing light when coolant level in the degassing box and ra diator is to low (Fig. 44).

1.Make sure engine is OFF. Remove start relay from the control center.

DANGER

Make sure engine and cooling system have cooled down prior to checking coolant system levels. Possible steam burns may occur when re- moving the pressure plug.

2.Make sure cooling system is full (see Check Cooling System in Chapter 4 – Peugeot Diesel Engine).

3.Disconnect connector from the sensor. Verify cir cuitry to the sensor at the connector using a jumper and multimeter.

A.Place ignition switch in RUN. Jumper from the pin for the tan wire to chassis ground, the red warn ing light should come on. Turn switch OFF.

B.Hold ignition switch in START. Battery voltage from the pin for the white wire to chassis ground should be indicated. Turn switch OFF.

C.Check continuity (1 ohm or less) from the pin for the black wire to chassis ground..

D.Replace light bulb or correct any problem circuit ry if necessary.

4.Reconnect connector to the sensor. Test sensor us ing the following steps:

A.Place ignition switch in RUN. The red warning light should be off. Turn switch OFF.

B.Hold ignition switch in START. The red warning light should be off. Turn switch OFF.
