Motorad Fail-Safe Thermostat for Ford and Mazda
Motorad Fail-Safe 7333-198 is an engine coolant thermostat built for OE-specified 198°F operation in demanding cooling systems. It is designed for Ford Explorer, Ford Ranger, Ford Aerostar, Mazda B4000, and Mazda Navajo applications where stable coolant control and reliable temperature response matter.
Key Features
- 198°F thermostat temperature for OE-style cooling system operation
- Fail-Safe design locks open if overheating occurs
- Copper case and wax compound for fast response to coolant temperature changes
- Offset design with air relief valve where applicable
- Rubber gasket/seal included
- Jiggle pin weep hole for air bleeding during service
- Manufactured to OEM specifications and processes
Product Details
This Motorad thermostat is part of the Fail-Safe line, a product line focused on controlled coolant flow and overheating protection. The copper case and wax element are engineered for quick thermal reaction, while the included seal and OEM-style sealing features support proper housing fitment. Motorad 7333-198 is a direct-fit thermostat choice for 1991-2000 Ford Explorer, 1990-2000 Ford Ranger, 1995-1997 Ford Aerostar, 1994-2000 Mazda B4000, and 1991-1994 Mazda Navajo cooling system service.
This part cross-references Four Seasons 73339 for the same application.
What It Helps Address
- Engine overheating caused by a thermostat that does not regulate coolant flow correctly
- Slow warm-up or unstable operating temperature
- Coolant circulation issues related to a sticking thermostat
- Air trapped in the cooling system after thermostat service
- Improper sealing at the thermostat housing
Installation Notes and Tips
Install Motorad 7333-198 with the sealing surface clean and free of old gasket material. The jiggle pin weep hole and air relief features should be oriented according to the vehicle’s thermostat housing design so trapped air can escape during refill. Verify the thermostat temperature rating matches the OE specification before installation on Ford Explorer, Ford Ranger, Ford Aerostar, Mazda B4000, or Mazda Navajo applications.
Quality Assurance
Manufactured by an OE supplier using OEM-quality materials, this thermostat is built to meet OEM specifications and safety standards for automotive cooling system service.
This part fits 35 vehicles
