LandCruiser HZJ75 1HZ Thermostat Replacement: Enhancing Engine Performance & Fuel Efficiency

Experience the rejuvenation of my LandCruiser HZJ75 (1991) with a thermostat replacement! After 22 years of faithful service, the old thermostat failed, causing erratic engine temperatures and decreased fuel efficiency. Upgrading from the old 76°C to a new 82°C thermostat not only stabilized the engine but also improved fuel consumption from 9.9 km/l to an impressive 12.1 km/l on long-distance trips. Join me in this step-by-step CZcams guide tailored for the 1HZ engine in the LandCruiser 75 series, and unlock the full potential of your vehicle for farm, town, and downstream driving. Discover how a simple replacement can revitalize your LandCruiser's performance and efficiency!

hi, i think that had to have a "rubber gasket" around the thermostat, in the old one you removed it together with the sealant/old gasket, the cod/part number from toyota is 16346-0k010

Hello there! May I ask why do you change the thermostat from oem 76c to 82c? Does your car run cold and temp drops when high speed using the 76c?

[@takashiiwamoto2001]

Hello, old 76c thermostat became too long to warm up after 20 years of operation. During high speed get warmed up but drop temp with speed reduction. So change new one that coincident got 82c. Since change new 82c my 1hz stays stable temp and better performance.
