Throw it away, the LR temp gauge is rubbish. Fit a decent one, VDO is good. The LR gauge (if it works) reads in the middle from 40 to 110c, so you are just as well off without it as it doesn't tell you anything.

could be a duff thermostat not working & staying closed. run the engine & check if the top hose gets warm as the stat opens.

changed the stat also m8 fitted a 91 deg so it runs warmer,what should the original stat open at any way.

We in the workshop are of the opinion that LR specifies gauges that 'read in the middle' all the time in order not to worry the punters. The VDO gauge in the TD5 is no different, showing normal no matter what the actual temp is. There is no excuse here because the gauge gets its signal from the ECU and the ECU knows the temp to the degree.

And this was (more or less) proven the other day when we had a guy in with a Disco 300tdi which he had overheated due to running at too high a speed with a roof rack and trailer in high ambient temps. He has a VDO gauge but didn't like the way it 'went up and down'. So he ignored it and cooked his engine. We are not sympathetic.

There is no substitute for brains.

Thanks for all the advice a friend had a LR gauge spare so i fitted this in the end & now after 10mins of running about the gauge reads half way.Never moves from half way but at least i now it works.

I agree....

check this link from East Coast Rovers in the US, regarding the in-built circuitry that LR install to make the temp guage stay "in the middle"...... :angry::angry:
