Replacing the cambelt (timing belt) and water pump on the 2014 Volvo V70 D2 diesel is definitely a job that requires some precision. But if you're comfortable with timing work, it’s doable at home with the right tools and this manual on hand. Here’s how you’d tackle it:
First things first: Disconnect the battery, jack up the front end, and remove the wheel and inner fender liner so you can see what you’re working with. To get full access to the belt, you’ll need to remove the auxiliary belt, engine mount, and timing covers.
Before you touch the belt, make sure to lock the crankshaft and camshaft at top dead center. The D2 diesel uses precise timing, and even half a tooth off can mess with fuel delivery or valve timing.
Once everything’s locked, loosen the belt tensioner, and slide the old belt off. Then you can get to the water pump — it’s bolted right to the engine block, driven by the belt, and usually sealed with an O-ring or gasket. Clean the mating surface, and install the new pump with a light coat of coolant-safe sealant if the manual calls for it.
To install the new timing belt, carefully route it over the crank, cam, idler, and tensioner in the correct sequence. Set the tension using the factory method (usually aligning a notch or pin on the tensioner), then rotate the engine by hand a couple times and recheck timing marks to make sure nothing slipped.
Once it’s good, button everything back up (covers, mount, belt, fluid, battery) and top off the coolant. Let it warm up and check for leaks and proper belt tracking.
They don't sound too bad, right? In any case, the service manual gives you torque specs, timing diagrams, and the full step-by-step procedure.
Good luck!
