Product Description

The Gates T312RB is a high-performance timing belt engineered for 1.7 L 4-cyl engines in 2001-2005 Honda Civic and 2001-2005 Acura EL - especially those built as interference engines. As part of Gates' "RPM / Racing" belt lineup, the T312RB uses premium materials (HNBR compound, aramid-reinforced teeth, fiberglass cord) to deliver significantly greater strength, heat-resistance, and wear resistance compared to standard belts - making it ideal for high-stress, high-RPM, or modified engine applications.

With 104 teeth and a 22 mm width, the T312RB timing belt maintains precise camshaft-to-crankshaft synchronization, which is critical for interference-engined vehicles to avoid valve-to-piston contact. Its reinforced construction helps resist stretching, cracking, and heat-related degradation - reducing the chance of belt failure under heavy load. The blue "Racing" finish signals the belt's premium build and strength, so it's often chosen by tuners, performance-minded enthusiasts, or anyone seeking long belt life under demanding conditions.

This belt is best suited for owners replacing a factory timing belt - whether for routine maintenance, performance upgrades, or as a preventative measure - on compatible 1.7 L engines. As with any timing belt change, inspect associated components (tensioner, idlers, water pump) and follow proper installation with correct tension and alignment. When installed correctly, Gates T312RB offers a durable, dependable timing solution with upgraded performance over standard belts.
