Mazda BT-50 Thermostat Housing
Choose a BT-50 thermostat housing
Compare the listed Mazda BT-50 housing with the original assembly before ordering. Match the generation, build date and engine, then check the mounting pattern, hose outlets and sensor connections.
Check the current diesel application
The BT-50 thermostat housing listing identifies B22/B32 2011–2020 2.2L and 3.2L diesel applications with reference BK3Q-8A586-AB. Read the complete product details and compare the original unit.

BT-50 thermostat housing questions
Are the thermostat, seals and sensor included?
Check the selected listing for its exact package contents. A housing listing does not automatically include every component required for the repair.
Does the reference confirm every BT-50 application?
Use the reference together with the engine, build details and original connections. Do not extend the listed diesel application to another generation without confirming the match.
