Im preparing for a trip to the cape next month and im not sure if I should do my timing belt before I go or not. I have a 2006 D4D with 138,000KMS and this is not due until 150,000kms. The question I have is have there been many cases of the original timing belts breaking early? Id hate for it to break while in the bush but if im justing the gun too much I would prefer to leave them until I get back. By the time I get back it will be at about 145,000kms (should be done soon after I know) but I would prefer to do the servicing as per the book kms as it will make it easier to keep track of for all future servicing. I know that a lot people do the water pump at this time too but when is it actually scheduled to be replaced? I dont plan on keeping the vehicle for much longer after 150,000 so would like to keep it all in line with the service book so the next owner knows what has and hasn’t been done and when etc.
Also, Is the timing belt tensioner also required to be replaced as part of the 150,000kms service or just noted to inspect and check?
