Toyota 4Runner, Tacoma, or Tundra owners with the 3.4L V6 engine - if you're approaching that 90,000-100,000 mile timing belt service interval, this complete kit has everything you need! It includes the timing belt, water pump with gasket, idler roller, tensioner roller, hydraulic tensioner, crankshaft seal, camshaft seals, thermostat with gasket, plus all your accessory belts for A/C, alternator, and power steering. This isn't some cheap parts bundle - the quality matches OEM standards and replaces part numbers like TKT025, TBK965AWP, and TBK271. The timing belt keeps your crankshaft and camshaft perfectly synchronized for optimal engine performance and fuel efficiency, while the water pump replacement prevents future cooling system failures. Doing both jobs together saves you labor costs down the road. Fits 1996-2002 4Runner, 1995-2004 Tacoma, 2000-2004 Tundra, and 1995-1998 T100 models with the 5VZFE engine. If you're experiencing overheating issues or it's just time for preventative maintenance, this kit gives you peace of mind knowing all critical components are being replaced at once. The installation does require mechanical experience, but if you're comfortable with engine work, this complete kit means you won't have to stop halfway through to hunt down missing parts. Keeping your timing system in sync is crucial for preventing expensive engine damage, and this kit makes that maintenance job much more straightforward and affordable!
