Product Details

This hydraulic timing belt actuator helps maintain proper timing belt tension in engines that use a hydraulic tensioner assembly. Dayco 85050 is listed for 2001-2005 Chrysler Sebring, 2001-2005 Dodge Stratus, 2005 Mitsubishi Eclipse built before 12/31/04, 1996-2004 Mitsubishi Eclipse, and 1996-2003 Mitsubishi Galant. The Dayco 85050 part number is also referenced in aftermarket and OE cross listings for the same application.

The Hydraulic Timing Belt Actuator product line is focused on timing belt systems that rely on hydraulic pressure to control belt tension during engine operation. For vehicles such as the Mitsubishi Eclipse and Mitsubishi Galant, correct tension control is critical to timing belt performance and engine synchronization.

Common Problems This Part Can Address

• Timing belt slack caused by a worn hydraulic tensioner
• Noise from an unstable timing belt drive system
• Improper belt tension after timing belt service
• Loss of timing belt control in high-mileage engines
• Service replacement for a leaking or weakened actuator assembly

Installation Notes

Verify engine application, model year, and build date before installation. For the 2005 Mitsubishi Eclipse, this listing applies only to vehicles built before 12/31/04. Follow the factory timing procedure, set belt timing marks carefully, and inspect related timing components during service. Use the correct service manual for the specific engine configuration.
