Symptoms
Usually none until it fails. The D24T's camshaft is belt-driven, so a truck without belt receipts should be treated as due. Refurbished trucks sold recently list a new cam belt and water pump among the first jobs.
The fix, step by step
- Take off the engine cover to reach the front of the engine.
- Replace the timing belt with its tensioner and pulley, then the water pump and seal while the front of the engine is open.
- Follow the VW/Volvo D24 procedure and the belt interval in your manual.
- Owners source most engine service parts as Volvo 740 turbo-diesel or VW LT items.
Tools & part numbers
- Engine locking tools for the D24
- coolant
