{"product_id":"1hz-washer-kit-aftermarker-washer-kit","title":"Injector Washer Kit Toyota 1HZ aftermarket","description":"\u003cp\u003eComplete 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.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's in the kit\u003c\/h3\u003e\n\u003cp\u003eBase washers, leak-off washers and heat shield washers — enough to complete a full injector refit on a six-cylinder 1HZ engine.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase washer OD:\u003c\/strong\u003e 18mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase washer ID:\u003c\/strong\u003e 12mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase washer thickness:\u003c\/strong\u003e 2.6mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeak-off washer OD:\u003c\/strong\u003e 19mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeak-off washer ID:\u003c\/strong\u003e 12mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeak-off washer thickness:\u003c\/strong\u003e 1mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat shield washer OD:\u003c\/strong\u003e 14mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat shield washer ID:\u003c\/strong\u003e 10.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeat shield washer thickness:\u003c\/strong\u003e 1.55mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSuits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eToyota 1HZ diesel engines\u003c\/li\u003e\n  \u003cli\u003eToyota Land Cruiser 80 Series (HZJ80, HZJ105)\u003c\/li\u003e\n  \u003cli\u003eToyota Coaster HZB50\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eNot sure if this kit suits your vehicle? \u003ca href=\"\/pages\/contact-simms-diesel\"\u003eGet in touch\u003c\/a\u003e with your engine details and we'll confirm fitment before you order.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNote: minor variations in colour or finish can occur between production batches.
