Allow the engine to cool down.

2. Remove Engine Covers

Sub-steps:
- Remove any plastic engine covers by unscrewing the bolts with a socket set.
- Carefully set aside the covers to access the timing chain area.

3. Inspect and Replace Timing Chain Tensioner

Sub-steps:
- Locate the timing chain tensioner; it is usually mounted on the side of the engine block.
- Unbolt the old tensioner using a socket wrench and remove it.
