UltraStat Product Line Details

Motorad UltraStat thermostats are engineered with stainless steel construction and valve control designed for consistent coolant flow management. The UltraStat line focuses on long service life, corrosion resistance, and smoother temperature transitions in the cooling system, making the Motorad 5267-195 a practical replacement for temperature-sensitive GM engines.

Detailed Description

This engine coolant thermostat is a fitment-based replacement for many GM cars, vans, and trucks from 1987 through 2009. It fits 2005-2009 Chevrolet Equinox, 2006-2009 Pontiac Torrent, 2002-2007 Buick Rendezvous, 2001-2006 Chevrolet Silverado 2500 HD, 2001-2006 GMC Sierra 3500, and many other listed applications. The Motorad 5267-195 is also cross-referenced to Dorman HELP 45899 for the same application.

What This Part Helps Address

• Engine running too cool or too hot due to thermostat wear
• Slow warm-up after cold starts
• Temperature fluctuation from a sticking thermostat
• Coolant flow control issues in high-mileage GM cooling systems
• Corrosion-related thermostat failure in older vehicles

Installation Notes and Tips

Verify the 195 degree F temperature requirement before installation and confirm the sealing flange, bypass dimensions, and gasket style match the original part. Replace the thermostat with the included rubber seal during cooling system service, and inspect the housing, coolant condition, and mating surfaces for debris or damage before reassembly. This part is listed for N/A position applications.

Quality Assurance

Motorad UltraStat thermostats use heavy-gauge stainless steel construction for corrosion resistance and long-life durability. BLVT valve technology is used to reduce thermal shock during coolant flow changes, supporting stable operation in the cooling system.
