first of all new to the site so hello all
my problem is this
i have a p reg astra 1.7td low blow astra estate .
if i keep the revs below 2 rpm then it behaves but if i raise the rpm to about 3 to 3.5 rpm the temp rockets up.
its ad a new water pump , flushed out numerous times had a new thermostat (taken that out though to stop it blowing up)
on normal driving it drives fine but if i go on a motorway thats when it rises .
plan to do the head gasket this weekend see if that sorts it , but if any off you have experiensed the same thing and no of anything else it could be then i would be gratefull to hear from you
hope you can help me out .
