Cooling/radiators etc - Ian (Cape Town)
Occasionally I go on a long drive (400 miles +), at speeds of 90mph +, in temperatures which can be as high as 35 degrees C.
Sometimes I have to slow down, for roadworks/passing through towns etc, and crawl along in stop-start traffic.
As you can imagine, the temp. gauge, which normally sits below a 1/4, shoots up to 3/4 way (sometimes above), and the electric cooling fan(s)kick in. But sometimes the temp stays up there for a while, until I start driving quicker again.
What would be the best thing to do when the road is clear? get up to high speeds again quickly (to get more airflow over radiator), or let the temp come down before hitting the loud pedal?

My tendency would be to drive at the speed at which the engine feels most comfortable (2/3 to 3/4 throttle?) until the temperature has normalised, then open up again.
