Goodyear Belts & Hoses 21023 Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21023 Timing Belt Tensioner is a hydraulic engine timing belt tensioner assembly. It is a key part of the engine timing system, and its job is to keep the timing belt at the correct tension.

Key Features:

• Applies steady pressure to the timing belt to keep it tight and prevent slack
• Helps keep the crankshaft and camshaft(s) in sync, so valve timing stays accurate
• Helps prevent the belt from skipping teeth on the pulleys
• Hydraulic tensioner assembly design
• Built for long-lasting durability and consistent performance
• Helps reduce wear on the timing belt and the risk of premature belt failure

Proper belt tension is critical to timing belt life and engine performance. Replace the tensioner along with the timing belt, following the vehicle manufacturer's recommended maintenance intervals, to help avoid serious engine damage from belt failure.
