Gates T249RB Engine Timing Belt

Gates T249RB High Performance Timing Belt

The Gates T249RB is a high performance automotive timing belt built for interference-engine applications that demand stable timing control under heat and load. It uses HSN belt material, fiberglass cord reinforcement, and a modified curvilinear tooth profile to support consistent engagement in demanding Nissan and Infiniti engine setups.

Gates RPM Timing Belts are part of the High Performance Automotive Timing Belt line, focused on stronger construction and heat resistance for higher horsepower engines. This blue timing belt includes timing marks for easier alignment during service and is engineered for applications such as Nissan Frontier, Xterra, Pathfinder, Quest, Pickup, D21, Maxima, INFINITI QX4, and Mercury Villager.

Detailed Description

The Gates T249RB timing belt is built for engines that require accurate camshaft and crankshaft synchronization in high-load conditions. Its HSN elastomeric composite construction is intended to handle elevated temperatures, while the fiberglass cord helps maintain belt stability over time. The 10 mm pitch, 133-tooth layout, and modified curvilinear tooth design support smooth operation in compatible Nissan and Infiniti interference-engine applications. This part cross-references Dayco 95249 and Cloyes B249 for the same application.

What It Helps Address

• Timing belt wear from heat and age
• Loss of valve timing accuracy
• Noise or irregular belt tracking in service
• Service replacement needs on interference engines
• Alignment challenges during timing belt installation
