Engine Cooling Thermostat for OE-Style Temperature Control

Motorad Fail-Safe 7320-170 is an engine coolant thermostat built for precise temperature regulation in demanding cooling systems. It is set to open at 170 degrees F and uses OEM-style materials and construction to support stable coolant flow in the applications listed below.

The Fail-Safe product line is designed with a lock-open safety feature that helps maintain coolant circulation if the thermostat overheats. For drivers servicing a Honda Passport, Isuzu Rodeo, or Isuzu Trooper, this Motorad thermostat offers an OE-spec replacement option with the temperature rating and sealing design needed for proper cooling system operation.

Key Features

  • 170 degree F thermostat opening temperature
  • Fail-Safe design locks open if overheating occurs
  • Copper case and wax compound for responsive temperature changes
  • Offset design with air relief valve
  • OEM-style seals used where applicable
  • Jiggle pin weep hole included
  • OE supplier manufacturing standards and OEM specifications
  • Sealing flange outside diameter: 2.52 in
  • Flange thickness: 0.068 in

Detailed Description

Motorad 7320-170 is an engine coolant thermostat engineered for direct-fit cooling system service in select Acura, Honda, and Isuzu vehicles. The 170 degree F calibration supports factory-style temperature control, while the copper case and wax compound are used to react quickly to coolant temperature changes. The offset design and air relief valve help support proper coolant flow and system bleeding during installation and operation. This part cross-references 73207 and P7320-170 for the same application.

Compatible With 1998 Isuzu Amigo, 1996-1997 Acura SLX, 1994-1997 Honda Passport, 1993-1997 Isuzu Rodeo, and 1992-1997 Isuzu Trooper. Motorad 7320-170 is a practical OE-style replacement for drivers searching for a 170F thermostat for Honda Passport cooling system service or an Isuzu Rodeo thermostat replacement.

What It Helps Address

  • Engine running hotter than normal due to a stuck thermostat
  • Slow warm-up or unstable operating temperature
  • Coolant flow restriction from a thermostat that no longer opens correctly
  • Cooling system service on vehicles requiring a 170 degree F thermostat
  • Replacement of a worn OE-style thermostat in Honda and Isuzu applications

Installation Notes and Tips

Verify the thermostat orientation, flange diameter, and temperature rating before installation. The jiggle pin weep hole and air relief valve should be positioned to help purge trapped air during refill. This thermostat does not include a gasket or seal, so use the correct sealing component specified for the vehicle and housing.

For best results, inspect the thermostat housing, coolant condition, and related hoses during service. Confirm fitment for your exact year and model before ordering, especially when servicing a Honda Passport thermostat replacement or an Isuzu Trooper cooling system repair.

Quality Assurance

Motorad manufactures this Fail-Safe thermostat using OEM-quality materials and OE supplier processes to meet factory-style safety and performance standards. The design is built to handle demanding automotive cooling systems while maintaining the specified 170 degree F operating range.
