my signal on the dashboard for the engine temp on my van has suddenly started going above 100c thus hitting the red danger level. however it only seems to happen when im driving slowly and changing gear regularly. when im on a motorway and driving at 60mph+ the temp drops back down to 90c where it should be.

does anyone know A) what im on about, cause im not great at explaining motor problems! and B) what i can do about it?

thanks lads

First thing to do is to run engine in neutral until it 'overheats' and check the fan cuts in. Then, more importantly, that the fan cools the engine and switches off again.

I would advise you get your local garage to carry out a full cooling system check carried out ASAP-to prevent the risk of any engine damage occurring.
