Low coolant module

Post by ttedj »

Anyone know where the low coolant module lives? Manual suggests somewhere in the front on the passenger side. It most definitely isn't working and it seems it controls the fan fail lamp test. Mine is staying on for about 5 mins, not the 6 seconds it should be.
Thanks

Sender/sensor is inserted in the front of the header tank. Check cable connection / clean connectors - might help.
The module is item 90 on page 17.03B of the service parts manual, although the diagram does not exactly specify the position; it is however shown with the relay bank over the driver's right leg and the delay unit for the wash wipe so I am guessing RH (driver's) side.

The connection has come off the tank and no warning except when cold for approx 5 mins from turning the key. Once warm the light is out except on the 6 second test when you turn the key. Will assume the lotus position and see if I can find it.

After assuming Lotus position, have found the module. It hangs down form under the dash behind instrument binacle. Also fitted to Rover SD1 and available from Rimmer Bros:
