What it does
A timing belt job is mostly labor, which is why tensioners, idlers and often the water pump are done at the same time. Using the correct part for your exact engine keeps oil pressure, sealing and timing where the engine was designed to run, and doing related parts at the same time saves taking it apart twice.
Installation & tips
- Replace the tensioner and idler pulleys with the belt, and double-check the timing marks before the first start.
- Water pump: On many engines the belt drives the water pump, so replace it while you are in there.
- Cam and crank seals: Leaking front seals can ruin a new belt.
- Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
