Goodyear Belts & Hoses 21005 Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21005 timing belt tensioner (also called an engine timing belt tensioner or hydraulic tensioner assembly) helps keep your engine's timing belt at the correct tension. The timing belt links the crankshaft and camshaft(s) so the valves open and close in step with piston movement. A tensioner that works properly is a key part of that system.

Key Features:

• Applies steady pressure to the timing belt to take up slack
• Helps prevent the belt from skipping teeth on the pulleys, which supports accurate engine timing
• Hydraulic tensioner assembly design
• Helps reduce wear on the timing belt, which supports longer belt life
• Replacement part from Goodyear Belts & Hoses

A worn or failing tensioner can lead to belt failure and serious engine damage. For that reason, many technicians replace the tensioner when they replace the timing belt. Follow the vehicle manufacturer's recommended service intervals and installation procedures.
