Goodyear Belts & Hoses 21020 Hydraulic Timing Belt Tensioner Assembly

The Goodyear Belts & Hoses 21020 timing belt tensioner is a hydraulic tensioner assembly. It keeps the 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 holds the belt tight helps prevent slack and tooth skipping, so valve timing stays accurate.

Key Features:

• Hydraulic timing belt tensioner assembly from Goodyear Belts & Hoses
• Applies steady pressure to the timing belt to take up slack
• Helps protect against belt skipping and timing errors that can damage the engine
• Replacement part for the engine timing drive system

Replace the tensioner according to the vehicle manufacturer's maintenance and replacement intervals. Many technicians replace it together with the timing belt.
