Goodyear Belts & Hoses 21010 Timing Belt Tensioner

The Goodyear Belts & Hoses 21010 Timing Belt Tensioner helps keep the engine 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 takes up slack. This helps prevent belt tooth skipping and keeps engine timing accurate.

Key Features:

• Applies pressure to the timing belt to keep it tight and reduce slack
• Helps prevent the belt from skipping teeth on the pulleys
• Supports timing belt life and engine reliability
• Goodyear Belts & Hoses replacement part, listed under the brand's engine timing belt tensioner hydraulic assembly range (MPN 21010)

Replace the tensioner according to the vehicle manufacturer's recommended service intervals. Many technicians replace it together with the timing belt. A worn tensioner can lead to belt failure and serious engine damage.
