Goodyear Belts & Hoses 21027 Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21027 Timing Belt Tensioner (also called an engine timing belt tensioner assembly) keeps the correct tension on the engine's timing belt. The timing belt links the crankshaft to the camshaft(s). This keeps the valves opening and closing in step with piston movement.

Key Features:

• Manufacturer part number 21027, listed by Goodyear as an engine timing belt tensioner hydraulic assembly
• Applies steady pressure to the timing belt to remove slack
• Helps prevent the belt from skipping teeth on the pulleys, which protects engine timing
• Helps reduce the risk of belt failure, which can lead to serious engine damage

Replace the tensioner at the same time as the timing belt, following the vehicle manufacturer's recommended service intervals.
