JimAttrill Posted April 2, 2007 Share Posted April 2, 2007 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.

western Posted April 2, 2007 Share Posted April 2, 2007 could be a duff thermostat not working & staying closed. run the engine & check if the top hose gets warm as the stat opens. Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted April 2, 2007 Share Posted April 2, 2007 Jim, Where did you source your VDO guages ? I can't find anywhere that does the gauge and calibrated sender unit as well...... Thanks in advance. Neil Quote Link to comment Share on other sites More sharing options...

Neil got my 2 voltmeters from europa spares click on the tab 'online shop' then left side bar 'instruments' then 'VDO' Quote Link to comment Share on other sites More sharing options...
mike4444244 Posted April 6, 2007 Share Posted April 6, 2007 Hi Forget TIM they are a bit cheap and nasty, go for VDO every time! they are very reasonable from here Mike Quote Link to comment Share on other sites More sharing options...
mmgemini Posted April 6, 2007 Share Posted April 6, 2007 If you want a good accurate gauge go for SPA. www.SPA-UK.co.uk Get a full face gauge. That way you can see the needle move. mike FOAK I can cause trouble in an empty house !!! Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted April 6, 2007 Share Posted April 6, 2007 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"......

western Posted April 7, 2007 Share Posted April 7, 2007 that must be only fitted to NAS spec vehicles as there's no listing of it in EPC for UK/European spec vehicles. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted April 7, 2007 Share Posted April 7, 2007 The gauge on my 90 works normally. Goes up when hot and down when cool..... Quote Link to comment Share on other sites More sharing options...
