AAAAAAAAArrrggghh coolant buzzer!!!!

Well having had a little play, the buzzer seems to go off even if I just have the electrics turned on, i.e. the engine is not running.

Which I\'ve never had before, therefore I guess it MUST be the sensor. I suppose if I wass changing spark plugs and this sensor is under the oil filter then I could have knocked it ?!

Quote from: nikpThe water temp sensor that the PFC and dash gauge uses is just under the oil filter. Bit of a pain to get to. This must be plugged in for the buzzer to stop. Also, as mentioned abive, there\'s a cable behind the ps pump that must be plugged in for the buzzer to stop.

Hi, just to let you know the PFC takes the water temp reading from the back of the thermostat house its the green plug.

cheers

Right got the car up on axle stands, had a look underneath can\'t see anything there. Had a look at the plugs by the power Steering, that is connected.

Tried Grounding it last night and the buzzer wouldn\'t stop.

So I guess it must be a broken wire in the part from the connector on the filler neck to the bit around the alternator. Hmmm.

Yeah, that makes sense! My bad. However, the other info I posted is correct. The buzzer will still sound if the water temp sensor plug is not conntected to the temp sensor under the oil filter, and there\'s a cable behind the PS pump that needs to be conntected properly for the buzzer to sound.

The buzzer can sound with the electrics on but no engine running. There have been many threads on this issue actually - Approximately 2 years ago there\'s even a thread started by me for the same reason.

Okay, after taking off the front strut brace, intercooler piping and the elbow I managed to find the connector you were talking about...and sure enough it wasn\'t connected. It looks as though someone has repaired it before and the wire had come off the spade connector.

So fingers crossed its sorted.

Thanks to everyone for their help!!! You may well have just saved my rex from several sharp kicks to the tyres!!! :rollin
