Goodyear Belts & Hoses 21004 Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21004 timing belt tensioner (also called an engine timing belt tensioner or hydraulic timing belt tensioner assembly) keeps the correct tension on your engine's timing belt. The timing belt links the crankshaft and camshaft(s). This keeps the valves opening and closing in step with piston movement.

Key Features:

• Hydraulic tensioner assembly design, listed by Goodyear in its Engine Timing Belt Tensioner Hydraulic Assembly line
• 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 and the engine damage it can cause
• Replacement part from Goodyear Belts & Hoses

Replace the tensioner at the same time as the timing belt, following the vehicle manufacturer's recommended service intervals. This helps the new belt last and keeps the engine timing accurate.
