Detailed Description

Motorad UltraStat 5420-195 is an engine coolant thermostat designed for 195F temperature control in a wide range of Chrysler, Dodge, Jeep, and Ram vehicles. This thermostat-only replacement is built from stainless steel and uses a rubber seal to support a secure fit in the cooling system. The UltraStat design is engineered to regulate coolant flow consistently while helping limit temperature spikes that can stress hoses, gaskets, and other cooling components. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Engine running too cool or too hot due to thermostat wear
• Temperature fluctuation after warm-up
• Coolant flow issues caused by a sticking thermostat
• Cooling system stress from thermal shock
• Seal leakage at the thermostat housing interface

Installation Notes and Tips

• Verify the vehicle requires a 195F thermostat before installation.
• Replace the thermostat only when the housing and related components are in serviceable condition.
• Use the included rubber seal and confirm the sealing flange seats evenly.
• The jiggle pin weep hole helps purge trapped air; orient it according to service procedure.
• Follow the vehicle manufacturer’s coolant fill and bleed steps after installation.

Quality Assurance

Motorad UltraStat thermostats use stainless steel construction and corrosion-resistant materials to support long-term cooling system service. The BLVT valve design is part of the UltraStat product line and is engineered to help maintain stable coolant control in demanding applications.
