removing thermostat for the summer? dw10 hdi

[eurotrotter]

with speeds greater that 75mph it goes to 85degrees

That’s normal, it takes quite some power to move at such speeds and the engine pedals hard and fast.
The makers tout top speeds of 120 mph and so, but they’re only good for the time to get there and back.
My petrol Xantia was only good for 90 mph, above that the temperature started to rise.

thanks for the comment cloggz, il just drive her on and hopefulyl she be alrite!
thanks!
