FAQ

Q1: How do I know if this thermostat fits my engine?

This thermostat is specifically designed for Hino W04D and W04D-T engine models. To confirm fitment, please check your engine nameplate or parts manual for the engine model (e.g., W04D-T) or the original part number (90014-6149). If your engine is a W04D variant, this part is highly likely to be compatible. Contact us with your engine serial number if you require further verification.

Q2: What is the correct installation procedure for a new thermostat?

Installation should be performed by a qualified mechanic. Key steps include: 1) Drain the coolant to below the thermostat housing level. 2) Remove the housing bolts and old thermostat. 3) Clean the mating surfaces thoroughly. 4) Install the new thermostat with the air bleed valve (if present) facing upwards. 5) Use a new gasket and reattach the housing, tightening bolts to the manufacturer’s torque specification. 6) Refill coolant and bleed the cooling system to remove air pockets.

Q3: What maintenance is recommended for the cooling system?

We recommend checking the thermostat’s operation annually or during major engine service intervals. The coolant should be replaced according to the engine manufacturer’s schedule (typically every 2-3 years) using the correct type of antifreeze/water mixture. A stuck-open or stuck-closed thermostat is a common cause of overheating or poor heater performance, so prompt replacement is advised if symptoms appear.
