Goodyear Belts & Hoses 21019 Engine Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21019 timing belt tensioner (also called a hydraulic timing belt 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.

Key Features:

• Applies steady pressure to the timing belt to keep it tight and take up slack
• Helps prevent the belt from skipping teeth on the pulleys, which keeps engine timing accurate
• Proper tension supports timing belt life and engine performance
• Listed by Goodyear as an engine timing belt tensioner hydraulic assembly

A worn tensioner can cause belt failure, which can lead to serious engine damage. Replace the tensioner along with the timing belt, following the vehicle manufacturer's recommended maintenance intervals.
