Cheers, I will look into that. Is there a way I can prove the radiator is blocked or just bite the bullet and hope the replacement cures the problem?

Thanks for the replies. Dazandtrace, when you say you had the same problem, were you towing? I don't have a problem without the caravan, it'll normally go all day without any rise in temp. I suppose it could depend on the degree of blocking.

2007 Grand Voyager 2.8 CRD Has anybody had overheating problems when towing a caravan on long hills? The temperature gauge rises steadily and would go into the red zone if I didn't slow down considerably. When the top of the hill is reached the gauge returns to normal very quickly. Friends who pull heavier caravans with smaller engine cars ( not Chrysler) don't seem to have a problem, they can maintain 60 mph or so while I have to slow below 40.
