Detailed Description

This Beck Arnley thermostat is built for drivers and technicians servicing Mazda CX-5, Mazda 2, Mazda RX-8, Mazda Protege, Mazda Protege5, Mazda 626, Mazda Millenia, Mazda MPV, Mazda MX-6, Mazda MX-3, and Ford Probe applications that call for a 180-degree engine coolant thermostat. Beck Arnley 143-0724 follows OE specifications for form, fit, and function, helping maintain proper coolant flow and engine operating temperature in the original cooling system design.

What It Helps Address

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant circulation during warm-up
• Temperature fluctuation from a sticking thermostat
• Cooling system service on Mazda and Ford vehicles with 180-degree specification
• Replacement of a thermostat that no longer opens and closes at the correct temperature

Installation Notes and Tips

Verify the housing condition before installation, since the housing is not included. Confirm the vehicle’s original thermostat temperature specification before ordering, especially on Mazda CX-5 and other Mazda applications listed for 180F service. Clean the sealing surface thoroughly and inspect the gasket or seal area during installation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
