changing my timing chain

[J.Lockhart]

Hey guys, need to change my timing chain and I was just wondering what was involved? do I just loosen it and swap or what?

In a nutshell:
Set engine at cyl #1 TDC on compression stroke. Rotor pointing to #1 wire. Disconnect battery. Drain radiator. Remove everything from the front of the engine including timing cover and balancer. Don't forget bolts that come up through the oil pan. Remove cam bolt, gears and chain. Align timing marks on new gears and install with chain. Put everything else back in reverse order.
