Automotive Replacement Engine Timing Part Sets & Kits

Timing kits typically include a timing belt or chain, tensioner(s), idler pulley(s), and sometimes water pump and gasket(s); some kits include only the belt/chain and tensioner components, so check the parts list for each kit

Select a kit by matching your vehicle's make, model, year, engine code, and drivetrain; verify OEM or aftermarket part numbers and consult fitment charts to ensure compatibility with your engine configuration

Yes—it's recommended to replace the water pump and all tensioning components when servicing the timing belt because they share service intervals and a failing pump or tensioner can cause premature timing component failure

Timing belts commonly require replacement every 60,000–100,000 miles depending on manufacturer recommendations, while timing chains are designed to last longer but may still need inspection or replacement if noisy, stretched, or during high-mileage service

Many reputable aftermarket brands provide quality kits that meet or match OEM specifications, but reliability varies by manufacturer; choose kits from established brands, check material and warranty information, and prefer kits that include all required components

Installation requires mechanical skill, proper tools, and precise timing alignment; if you lack experience or the necessary tools, professional installation is recommended because incorrect installation can cause severe engine damage

After installation, follow the manufacturer's torque specs and break-in procedures, inspect for leaks or abnormal noises during initial operation, recheck belt/chain tension after the first few hundred miles if recommended, and keep records of the service for future reference
