Could really use some advice and guidance if possible. My Td5 recently had issues with the turbo (worn end float) and exhaust outlet manifold (warped). I replaced both, using a reconditioned Garrett Turbo from a well know remanufacturer. The turbo sounds loud when I drive, whistling / whining but the car runs and drives ok. I recently towed a caravan down to Dorset for the weekend and had quite a few problems. The engine has a viscous fan but I kept hearing what sounded like the fan kicking in and running for a few minutes before shutting off. This kept repeating every ten minutes whilst on the motorway and the turbo sounded like it was struggling. I was doing approximately 60mph steady. Off the motorway the fan never kicked in. I have towed with this vehicle for a number of years and never had an issue until now. I don’t have air con so it’s not the pump. Also I replaced the auxiliary drive belt and two pulleys a couple of months ago. I am being advised that the belt looks worn and cracked already. Would greatly appreciate any inspiration here as I am due to go up to the Lakes soon with said caravan. The vehicle has done 130k. Thanks in advance.
