D24T - Volvo 740 - slow to warm up?

My gauge sits around 1/3 on flat ground unless running over 90MH for too long, then it heats up.

Thanks for the reply, did you mean 90MPH or KM/H?

I'd just like to establish what is normal behaviour

I tested the 'stat I removed and it seemed to operate fine. So I'm still at a loss as to the slow warm-up I'm experiencing... I think I'll change the temp sender on the weekend

Both of mine sit straight up halfway after 5-10 minutes driving from cold. Moving maybe a needle width higher when under high load.

thats MPH

With an 87C stat at normal speeds it sits below the half mark on flat ground, but will rise on hills

Thanks folks

Ive ordered a new temperature sender unit (mine is a 2 wire type and quite hard to track down) so hopefully that should sort it. At present, my heater blows 'slightly warm' air before the needle even reaches the start of the line on the gauge, so I suspect the gauge could be not as accurate as it should be!
