Technical Temperature Gauge Query

[Tierneykong]

Hi,

Thanks for the great info in my last post, I do have another question tho. I have a mk2 Sporting, I've only had it a couple of weeks but I've noticed recently that the temperature gauge is doing something strange. Initially when I drive the car the gauge climbs nicely up to the halfway mark but after a while it starts to drop slightly below half (sort of in between 1/4 and 1/2) it then goes up and down between these points for the duration of the drive. It never gets hot tho or even goes remotely above halfway. I had another Mk2 Sporting before this, the gauge on that always went to the halfway mark and stayed there. Any ideas if something is wrong here. Should I be worried?
Thanks in advanvce guys.

What is the state of the coolant?

The Coolant is full (now that I've looked at it its a slight bit over the full mark), I dont seem to be loosing coolant or anything like that though.

Thanks

It's probably just showing the fluctuations in temperature as the thermostat opens and closes. You'd get a dip the first time it opens and cold water mixes with the hot water. However, fluctuations should settle down. Maybe the thermostat is playing up.
