Continental 40319 Engine Timing Belt

Continental 40319 Timing Belt Overview

Continental 40319 is an engine timing belt built for precise valve train synchronization in select Volvo applications. It uses EPDM material and precision-molded teeth to maintain consistent contact with cogged components, while the belt construction is engineered to resist heat, abrasion, ozone, shrinking, and elongation.

Compatible with 2000-2005 Volvo S80 and 2003-2005 Volvo XC90 interference engine applications, this Continental timing belt supports accurate camshaft and crankshaft timing in demanding engine service. The 40319 timing belt is a direct-fit service part for owners searching for a Volvo S80 timing belt or Volvo XC90 timing belt replacement.

Key Features

• EPDM construction for durability in high-heat engine environments
• Precision-molded teeth for consistent engagement with timing components
• HTD 9.525 M tooth profile
• 146 belt teeth for specified timing applications
• 1.100-inch top width and 54.748-inch belt length
• Designed for interference engine applications where timing accuracy matters
• Continental part number 40319 for catalog matching and service lookup

Detailed Product Description

Continental 40319 is an engine timing belt made for valve train service where accurate synchronization is critical. The EPDM belt material helps resist shrinkage and stretch over time, while the molded tooth profile promotes steady contact with the cogged drive system. These construction details support stable timing performance in the Volvo S80 and Volvo XC90 applications listed below. For buyers comparing timing belt replacement options, the 40319 timing belt is also referenced under Continental TB319, Dayco 95319, and Gates T319.

This part cross-references Dayco 95319 and Gates T319 for the same application.

What This Timing Belt Helps Address

• Engine timing drift caused by belt wear or elongation
• Noise or irregular operation from a worn timing belt profile
• Loss of tooth engagement from aged or heat-damaged belt material
• Service replacement needs on interference engine applications
• Fitment searches for Volvo S80 timing belt and Volvo XC90 timing belt service

Installation Notes and Tips

Install the belt only on the confirmed applications listed here: Fits 2000-2005 Volvo S80, N/A, interference engine application; Fits 2003-2005 Volvo XC90, N/A, interference engine application. Verify tooth count, belt length, and tooth profile before installation, and inspect related timing components for wear during service. Because this is an interference engine application, correct timing alignment is essential during replacement.

Quality Assurance

Continental timing components are built to meet the dimensional and material requirements needed for engine service. The 40319 timing belt uses EPDM construction and molded tooth geometry to support consistent fit and timing performance in the specified Volvo applications.
