The timing chain is responsible for connecting your vehicle’s crankshaft to the valvetrain or camshafts.
The timing chain is located at the end of the camshaft, which is typically at the front of the engine. How do you find which part is the front? It depends on whether your engine is mounted longitudinally or transversely. This will depend on whether the vehicle is a front or rear-wheel drive.
A rear-wheel or four-wheel drive engine needs to be oriented in a way where the drivetrain is pointed toward the rear. So, if you’re driving a rear-wheel or four-wheel drive vehicle, the timing chain would be on the part of the engine facing the vehicle’s front. This is the case with Ford F-150s. If your vehicle is front-wheel drive, then the timing chain will be on the left or right side of the engine.
If you’re trying to access the timing chain on a 1997 to 2003 Ford F-150, you’ll need to remove the radiator fan, serpentine belt, and pulleys, which connect to components like the power steering pump. The intake manifold and intake hose are also directly above most engines, so you might also need to remove them to access this part. Lastly, the timing chain on many vehicles has a timing chain cover that protects it from debris. So you’ll need to remove this as well.
Tips on How to Access the Timing Chain
Accessing the timing chain is a labor-intensive process since there are many components along the way. The timing chain is typically located near components like the serpentine belt or the drive belt, which transfers power from the engine to components like the A/C compressor, power steering pump, and starter.
