Xantia: Which Thermostat?

Hi,
I have an early 1.8 8V petrol Xantia that had an 89deg thermostat fitted.
I've recently replaced it with an 83deg one because that's the only one I could get locally.

As you know, the spec for the Xantia thermostat was changed in 1997 from 89deg to 83deg. Was this by design, or was it found that the engine was running too hot at 89deg?

Should I change back to an 89deg one?

Thanks in anticipation.

Mine has 83°C installed but I think petrol 8V models have 89°C.

Anything around that temperature is good enough, you are not going to loose much efficiency for a few degrees.

Agree, what is 6°C in that high a temperature.

It's probably the difference between driving like an old man and 'enthusiastic' driving.

When I drive to work my oil temps half way on the gauge, and when doing motorway speeds, it will be up a 1/4 of a notch up, no biggie really is it.
