Detailed Description

Motorad 241-192 is an engine coolant thermostat designed for vehicles that require a 192F OE-specified opening temperature. The Standard product line focuses on direct-fit thermostat service with OEM-quality materials, including a copper case and wax element that react quickly to coolant temperature changes. This helps maintain proper engine operating temperature in applications such as Mazda B3000, Mazda 626, and Isuzu Pickup cooling systems.

This part cross-references Gates 24192 and BBB Industries 13859 for the same application. The thermostat is built with a standard design, a jiggle pin weep hole, and OEM-style sealing features where applicable. It is a practical replacement choice for drivers servicing older Mazda, Isuzu, Geo, Nissan, and Subaru cooling systems that call for a 192 degree thermostat.

What It Helps Address

• Engine running too cool or taking too long to reach operating temperature
• Temperature fluctuation caused by a worn thermostat element
• Restricted coolant flow from a thermostat that no longer opens at the correct temperature
• Cooling system service on vehicles requiring a 192F thermostat specification
• Maintenance replacement for aging OE thermostat assemblies

Installation Notes and Tips

Verify the thermostat housing style and temperature specification before installation. Clean the sealing surfaces thoroughly and inspect the housing for corrosion or warpage. The gasket or seal is not included, so use the correct seal for the application where required. The jiggle pin weep hole should be oriented to help air escape during filling and bleeding.

Confirm fitment by year, make, and model before ordering.
