Thread: temperature gauge

Had a similar problem with my old Pajero. It was fine until I was towing a heavy boat up big hills/mountains at which point the temperature went sky high. Happened over 6 months or more.

Eventually it ended up blowing a radiator hose and needed a new thermostat and radiator etc. Luckily I was only about 3 km from my mechanic when it happened so I got the car towed straight there. I was lucky I didn't end up wrecking the motor.

Different car, but my advice would be to get it checked out sooner rather than later as whilst you're only experiencing problems under load now you can bet your bottom dollar there's something wrong.

Does anybody know if the D4 temp gauge "tells the truth"????
If you have owned a TD5 D2 you will know the gauge is a computer generated value,ie it stays on half once warm and doesnt move until it gets to 107degC.
If its the same I will be buying an aftermarket temp sensor.

Andy, It is normalised like the D2.

Andy, my D3 gauge does not tell the truth so I monitor water temp using a scan gauge. My normal temp is around 95 (+/-4) and max I have seen was 101 and the temp gauge did not move an mm. I'm not sure this is the best way to monitor temp but at least the scan gauge gives unfiltered real time info from the temp sensor (which gives me a warm and fuzzy feeling given my gross distrust of the plastic cooling system bits).

Normalised gauges were born out of panic stricken public freaking out when the gauge went above half way mark.

There are thresholds at which it should move noticeably.

A scan gauge is a great addition without having to hack into the cooling system.

Haven't looked, but does the D4 have a low coolant alarm built in?

My d3 has a low coolant warning but apparently it will only sound when the overflow tank is defective or after the system has emptied out via a plastic bleeder and spat a head gasket ... Assume d4 would be the same or improved.

I have an old car with an old style temp gauge that I really like ... It actually moves when vehicle is hot (such as stop start traffic) ... Very honest gauge that has saved my bacon on at least one occasion due to a failed water pump. My new v8 holden hatchback has the worst gauge I've yet used - cold or normal that's it (and it reads normal long before it's actually up to operating temp).

My Low Coolant Level warning saved me when my plastic breather failed. My leak was slow so it triggered the warning before the header tank was empty.

My main issues is that it doesn't trigger any major bongs or warnings, just the little "i" pops up in the LCD display. When I saw it my wife said it had been on for the last week or so.

My nose saved me when mine started seeping (and my habit of opening the bonnet each time I fuel up ... So quite often haha).

Did you replace yours with a metal one preacher ? If so, what did you use and where did you source it ?
