GENUINE Toyota LandCruiser 40 45 60 61 75 Series HJ 2H 12HT H Thermostat 90916-03026

Product Description

Up for sale is a 100% Genuine Toyota Engine Coolant Thermostat (82°C Standard Temp). This factory-original mechanical valve controls and regulates the engine's coolant flow to ensure your classic Toyota diesel block warms up quickly and stays at its optimal operating temperature.

Unlike cheap aftermarket thermostats that can stick shut, open unevenly, or cause dangerous temperature spikes, this authentic Japanese-made OEM unit features a heavy-duty copper bypass actuator and calibrated thermal spring. It is engineered by Toyota to survive harsh outback heat, heavy towing, and severe engine block vibrations without fatigue.

• Manufacturer Part Number: 90916-03026 / 9091603026

Key Features:

• Calibrated Thermal Flow: Prevents engine overheating or running too cold, which directly protects your head gasket and optimizes fuel consumption.
• OEM Structural Integrity: Built from premium high-tensile brass and stainless steel to resist scaling, corrosion, and bypass leakages.
• Direct Cross-Reference Numbers: Replaces obsolete and superseded Toyota part codes: 90916-03058, 90916-03066, 90916-03077, and 90916-03102.
