Injector Washer Kit Toyota 1HZ aftermarket

Complete aftermarket washer kit for reinstalling injectors on the Toyota 1HZ — the naturally aspirated six-cylinder diesel found in the 80 Series Land Cruiser and HZB50 Coaster. Unlike the turbocharged 1HD variants, the 1HZ uses three distinct washer types per injector including a heat shield washer between the injector and the combustion chamber. All three types should be replaced every time injectors are removed. Reusing old washers is one of the most consistent causes of compression leaks, heat soak damage around the injector bore, and poor sealing after a refit. What's in the kit Base washers, leak-off washers and heat shield washers — enough to complete a full injector refit on a six-cylinder 1HZ engine. Specifications Base washer OD: 18mm Base washer ID: 12mm Base washer thickness: 2.6mm Leak-off washer OD: 19mm Leak-off washer ID: 12mm Leak-off washer thickness: 1mm Heat shield washer OD: 14mm Heat shield washer ID: 10.5mm Heat shield washer thickness: 1.55mm Suits Toyota 1HZ diesel engines Toyota Land Cruiser 80 Series (HZJ80, HZJ105) Toyota Coaster HZB50 Not sure if this kit suits your vehicle?
