DIY: Replace Your Timing Chain
Replacing a timing chain is not as daunting a task as it seems. With a few hours and some common sense, you'll be able to replace your own timing chain and gears. |

Disassembly
- Disconnect the negative terminal of the battery.
- With the radiator cap removed, drain the old radiator coolant into the drain pan or bucket.
- Remove the upper and lower radiator hoses.
- Remove all the drive belts.
- Remove the fan and fan clutch assembly.
- Remove any brackets attached to the water pump or front timing cover.
- Remove any heater hoses that may be attached to the water pump and remove the water pump.
- Remove the pulley or pulleys from the harmonic balancer.
- Remove the harmonic balancer with the harmonic balancer puller.
- Remove the fuel pump and plug the attaching lines.
- Remove the front timing cover. You may need to remove or loosen bolts from the front of the oil pan.
- Rotate the engine with the ratchet and socket until the timing marks on the gears are aligned in a perpendicular fashion. For the specific timing alignment on your engine, consult a service manual.
- Remove the camshaft bolt or bolts and pull forward on the cam sprocket and timing chain to remove the chain and cam sprocket. With a three-jaw gear puller, remove the crankshaft sprocket. On some engines, it may simply pull off without the use of a puller. Always replace the sprockets when replacing the timing chain, as the old sprockets will be worn from the old chain.
