Temperature gauge reading a bit low?

Hello,

Ever since I bought my 2000 V70XC the temperature gauge never quite gets to the 3 o'clock position. It always stops right between the 3 o'clock mark and the mark below that (see photo). It never fluctuates but always comes just shy of the 3 o'clock mark. And in case you are wondering, I am 100% sure the engine is all the way warmed up.

I'm not sure if this is normal on this year/model. I just know that when I had my 98' V70 it would always go to exactly the 3 o'clock mark on the gauge.

The question I have is: Should I be looking to replace the ECT sensor?

Thanks,

Eric

It could be oxidation creating a high resistance on the ECT electrical connector. Considering that the car is 20 years old it a good probability. Try cleaning the ECT electrical connector with MAF cleaner or Electrical contact cleaner.

You can think of the gauge as a stop light , three colors

Cold, ok, overheat

In one of my threads I documented the temperature and gauge position for one of my cars, I’ll search

Found it, it was the T5

I would try a new thermostat as they're cheap and easy to replace. If that doesn't work, new OEM ECT wouldn't hurt, especially if it's original. Your temp doesn't really look bad though.

My 2000 XC is always right at 3 o'clock position.
