Thread: 2000 D2 V8 Temperature Gauge

That doesn't sound right, or very good at all. Mine is constantly just under half way, regardless of the outside temperature or the aircon.

Your coolant shouldn't be half full either. I'd be topping that up as a start and then road testing it to see if that has helped.
If it's low now, make sure you check for any leaks after the top up and check under the car for any evidence of leaks.

Fingers crossed it just needs some coolant and hasn't got stuffed heads.

if the gauge moves at all after reaching operating temp then something is wrong,,,

and maybe the reason why the last guy sold it---

No, it is not. The temp gauge on your D2 will not show you what is really happening - they respond very slowly because they are over damped. By the time the temp gauge has gone into the red your engine has already overheated.

My own experience with D2 V8 is that the radiators foul up after 5-7 years. If that radiator is ~10 years old then it needs attention - either changing or rodding out IMHO.

Neglect the cooling system and you are asking for trouble - head gasket leakage but sometimes worse, slipped liners.

Should not be losing water either, you need to understand why that is happening.

Ah. I was secretly hoping nobody was going to mention the heads. Will try your top up suggestion and get someone who knows to look into it.

Thanks again!

Mine, same MY, sits at 3 O'clock when warmed up.
I have it in Karratha, and have had it run 10000K since I bought it. 38C...pffft, nothing, and with both airs on flat out. (I was also born in shoe box in middle of road...luxury).
The diseasel I had a few years back, was the same...temp gauge pointing steady at 3 O'clock.
Nat-Rad or some other radiator mob should easily, and while you wait, be able to identify HCs in the coolant, meaning head issues, also a simple pressure check to find any external leaks.
It maybe as simple as a sticky thermostat???
I would also recommend you invest in an "engine saver" coolant level alarm...cheap insurance.

just had my heads removed for new gaskets,, around 1400 including labour, good gaskets, and new studs. oh take off an hour or so unless you have gas too--

Just for the record; in case anyone else ever runs into a similar issue, it turned out that the radiator was 60% blocked! Had it cleaned out and installed a new water pump since it had been under strain. All is better now.
