you will be needing the following for this operation:
Before You Start:

Why Replace Your Timing Chain?
- Follow these instructions carefully. Read and be sure you understand them before you begin.
- Gather together all of your tools and supplies before you begin.
- Allow plenty of time to do the job so you don't have to hurry.
- Remember that these are general instructions. For more
detailed instructions pertaining to your specific vehicle, consult an
appropriate repair manual.
- Safety is important whenever you're working around machinery. Beware of hot objects, sharp instruments and hazardous materials.
- Don't substitute tools unless you're sure you won't compromise either your safety or the performance of your vehicle.
- Never work on a vehicle that is only supported by a jack. Use
jack stands to support the vehicle while you work. Work on a solid,
level surface. Never jack a car up on dirt or grass.
Over time, wear on internal working parts of your engine will
spell the need for replacement. One of the internal working parts that
wear is the timing chain and timing sprockets. The timing chain and
sprockets are the connecting line between the crankshaft and the
camshaft. As the crankshaft turns, via the timing chain, it drives the
camshaft that operates the engine's valves via the lifters, push rods
and rocker arm assemblies The timing of the valves opening and closing
at precise intervals is crucial for proper engine operation. As the
timing chain and sprockets wear, this precise timing of the valves
gradually changes, eventually to a point where replacement is necessary.
Telltale signs of worn out timing chains are:
Sluggish performance and poor economy.
Sudden engine performance change including the inability to start the engine.
Intermittent backfire through the intake manifold.
Inconsistent ignition timing or a clattering noise coming from the front of the engine.
Before starting the disassembly procedures, I would suggest
cleaning the engine with an engine degreaser. A clean engine is easier
to work on and helps prevent dirt or contamination from entering the
engine during disassembly.
Call for a mechanic help if the task is too much for you.
