Hi i have a 1993 ZX td and was woundering where the temp gauge should be once on a motoerway at 65 mph. my one is just under to 90.

Sounds about right. I think the thermostat opens at 89 degrees.
At 65 the heat output of the engine will be less than the cooling effect of the air passing through the radiator, so you should stabilise at around the 'stat temperature.
