Fact-checked. Built from OLP's spec database, then independently fact-checked line by line with every correction applied. Master-tech sign-off by Chris Hackleman is queued. Cross-check torque values against the factory manual, and stop if anything looks unsafe. How our data is made.

Replace the timing chain tensioner on the 3.0L V6 Twin Turbo engine to restore proper timing chain tension and eliminate timing-related noise or performance issues.

Warnings

⚠️This engine uses interference timing. Incorrect timing will cause catastrophic valve-to-piston contact and engine damage.
⚠️Never rotate the engine without timing pins/locks installed once timing components are loosened.
The crankshaft pulley bolt requires significant torque. Ensure proper holding tool is engaged before loosening or tightening.
RTV silicone must cure for at least 30 minutes before adding fluids. Follow manufacturer cure time specifications.
ℹ️This procedure covers one bank. The V6 has two timing chain tensioners (one per bank). Verify which bank requires service.
