Motorad 5228-195JV Engine Coolant Thermostat

Motorad UltraStat 5228-195JV Thermostat

Motorad UltraStat 5228-195JV is an engine coolant thermostat built for Ford, Lincoln, and Mercury applications that call for a 195°F operating temperature. It uses heavy-gauge stainless steel construction for corrosion resistance and long service life, with BLVT valve technology to reduce thermal shock in the cooling system.

Key Features

• 195°F engine coolant thermostat for OEM-spec temperature control
• Heavy-gauge stainless steel construction for durability and corrosion resistance
• BLVT valve technology helps minimize thermal shock to cooling system components
• Jiggle pin weep hole included for air bleeding during service
• Bypass diameter: 1.09 in; bypass length: 1.37 in
• Sealing flange outside diameter: 2.12 in; flange thickness: 0.06 in
• No gasket or seal included

Product Details

The Motorad UltraStat line focuses on thermostat durability and stable coolant regulation. This 5228-195JV thermostat is engineered around a 195°F set point and uses stainless steel construction to resist corrosion in demanding cooling systems. The jiggle pin weep hole supports proper coolant flow and air evacuation during installation and service, while the BLVT valve design helps reduce abrupt temperature changes that can stress hoses, radiators, and other cooling system parts. This part cross-references Stant 45399 for the same application.

Fits 1997-2014 Ford F-150, N/A; fits 1999-2021 Ford F-250 Super Duty, N/A; fits 1999-2022 Ford F-350 Super Duty, N/A. It also fits a wide range of Ford, Lincoln, and Mercury vehicles including Expedition, Navigator, Explorer, Mustang, Crown Victoria, Town Car, Grand Marquis, and Mountaineer applications. Motorad 5228-195JV is a direct-fit thermostat choice for many 195°F cooling system setups.

Common Uses

• Restoring proper engine operating temperature after thermostat failure
• Addressing overheating caused by a thermostat stuck closed
• Correcting slow warm-up from a thermostat stuck open
• Replacing a corroded or worn thermostat during cooling system service
• Maintaining stable coolant flow in Ford F-150, F-250 Super Duty, and F-350 Super Duty applications

Installation Notes

Verify the required thermostat temperature and housing dimensions before installation. This part does not include a gasket or seal, so the existing seal should be inspected and replaced if needed. Clean the mating surfaces thoroughly, confirm bypass fitment, and orient the jiggle pin weep hole correctly during assembly. Motorad 5228-195JV should be installed only in applications specified for a 195°F thermostat.

Quality Assurance

UltraStat thermostats are built with stainless steel construction and BLVT valve technology to support long-term cooling system performance and corrosion resistance. The design is intended to meet OEM temperature specifications for the listed Ford, Lincoln, and Mercury applications.
