    I have a 2009 CRD 3 litre diesel. It works just fine when being driven normally. But when towing a caravan, GTM2900, it overheats to within one bar of  red on the temperature gauge. The fan does not appear to be working as hard as it should. This is intermittant and seems to be not related to outside temperatures as it happens in 15c as well as 35c. I have taken it to two dealers who say they cannot find a problem. There is definately a problem I just need some technical advice to help track the problem down.

      I would check two of the following things:

      Viscous Clutch (if you vehicle has one, its located in front of the hydraulic fan)

      Might look like this Click to englarge

      Or check the electirc fan module / relay located under the battery container. 9/10 times it's the relay or fan module.

      They look like this: Click to englarge

       

      Instructions on diagnosing the cooling system are below:
