Goodyear Belts & Hoses 21009 Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21009 Timing Belt Tensioner is a replacement hydraulic timing belt tensioner assembly. It is also called an engine timing belt tensioner. It keeps the correct tension on the timing belt so the engine's timing system runs reliably.

Key Features:

• Maintains proper timing belt tension and prevents belt slack
• Helps keep the crankshaft and camshaft(s) in sync so valves open and close at the right time
• Helps reduce timing belt wear and the risk of premature belt failure
• Hydraulic tensioner assembly design
• Goodyear Belts & Hoses part number 21009

Replacing the tensioner when you replace the timing belt is a good preventive maintenance practice. It helps protect against belt damage and costly engine repairs.
