temp where should it sit

[hazards_golf74]

i ask this because mine sits about half way when on the high way and bout 3/4 in town. and it seam to be using a fair bit of water, but ive looked around and cant find any leaks and i had it pressure tested and no leaks there either.
so any help would be much welcome

thanks Tristan

The radiator cap will cause them to run hot very quickly and will cause coolant loss. Less than $20, its not a bad place to start.
The temp gauges on different Mk1s run in different ranges. The only way to see how hot it is getting is to stick a temperature gauge in the radiator when the car is idling at standstill.
Good luck, Andrew

As Andrew said, alot of them all read different.

I've had several mk1's & some of them had normal reading's at 1/4 getting upto 3/4 before the thermo cutting. Some have stayed at half the whole time, & my gti's normal reading's are 1/4 to half before the thermo cut's in.

The cap is a good place to start.

Maybe also check your thermostat & waterpump housing for leak's. Another place that is over looked is your heater core. Can leak without knowing.

What's the oil like under the oil cap? Milky?
