water temp guage

[29south]

 

Any advice please

The temperature guage (1600 K) immediately goes to the red on start up - water levels fine and too soon to be actually be temperature related. What/how do i start testing to find the fault? Thanks

Have you already got a wiring diagram (let me know if you want one)  and a multimeter?

Have you found the temperature sensor?

All other instruments and electrics OK?

Very likely a faulty sender sender shorting to ground internally. I'd eliminate that possibility before looking elsewhere. There are two temperature senders on the water rail on the exhaust side of the engine towards the back. Probably a brown sensor with a two pin plug for the ECU and one sender with a single wire on a spade terminal or similar. If so, unplug the single wire sender. If the gauge then goes to zero, replace the sender. If not, post back on here!

Revilla, thanks v much detaching the single wire showed the faulty sender - now what do i ask for when seeking a replacement?

Just call Chris at Redline 01883 346515 and ask for Rover temperature sender for the gauge.
