G'day,
I am having trouble with my b2500 overheating.So I am told there is a problem specific to this motor but no one can actually tell me what it is.
Any feedback would be appreciated,

My father has a B2500 that was overheating when towing a heavy load. The cooling system was cleaned and found to be in excellent condition. The fluid drive coupling for the fan was then replaced. This did not work. I have designed 8 brackets which lock the fan to make it direct drive. This has solved the problem. The vehicle is presently towing a caravan around Australia and has no problems. These brackets were manufactured by a Tool Maker and a precisely made to fit the vehicle.
