Thread: Summer High temperatures, Td5 temp gauge never moves?

as you mentioned my understanding is the guage only moves beyond normal when you have a big increase, probably followed by clouds of steam.
stops people panicking when the engine temp rises by 0.5'C.

I suppose it comes down to servicing and paranoia
Most modern cars temp guages wont move untill its critical,, If you are confident with your servicing/work on your car, then forget the temp guage,, by the time its gone into the red zone all the coolant is on the road anyway--,,

lots of temp monitoring devices around if you are concerned--

After all the work on this silver one I'm happy to run without,,
I'd rather have a gearbox temp guage

Yes, as stated, the Disco temp gauge is well known not to indicate overheating until its too late. I run a Scanguage which monitors water temp and so far I have seen temps from 91 through to 105 and the factory gauge didn't move.

I saw mine move once- the fan propellored into the radiator while under water and there was a sudden catastrophic loss of coolant.
The standard gauge is useless for monitoring engine temperature, and alerting critical situations before serious damage is done.
This is why I have an after market temp gauge and alarm, and a coolant loss monitor.
On a recent trip massive amounts of spinifex seed clogged the radiator. With 40 degrees ambient, I knew early when I had to turn off the AC and reduce speed. The OEM gauge remained happy throughout.
Hosing out the seed fixed it (not something that can be done in most remote desert locations).

I'm with Roberto and others on this subject. I'm paranoid, pedantic and peculiar about what's going on with my engine, especially the cooling system.
I have a Madman EMS2 and an engine saver alarm fitted. I can monitor coolant temperature and coolant level x2 sensors. Best insurance you can buy.

I fitted a TM2 combo (temp and low coolant). Easy to fit and interesting to watch temperature vs gauge. My gauge goes to halfway at about 60 C and doesn't move at up to 98 C - the highest I've achieved so far!

I feel a lot better...

IMO, a mandatory aftermarket fitting is an egine-saver alarm. No-one knows when a hose may give way, or a slow leak will draw down your coolant to a critical level. An engine-saver alarm will give you piece of mind Bob

The only way to go,the temp. guage is electronically controlled,been a few threads on this a while back.
If you see it up in the red,more than likely it is too late.
I know it seems silly,but that is the way it is.A lot of other vehicles are the same,our hiace work vans are the same.

As others have said,TM2 is the other way to go,for my D2 i had the engine saver.
