Detailed Description

The Motorad Standard 423-195 thermostat is engineered for vehicles that require a 195F engine coolant thermostat with OE specified temperature control. Its copper case and wax element are designed to react quickly as coolant temperature changes, helping the engine reach and maintain the intended operating range. The included rubber seal and OEM-style sealing details support a proper housing interface during replacement service.

This part cross-references Gates 52395 and Stant 14399 for the same application. It is a direct-fit option for many Chevrolet C1500, GMC K1500, Ford E-350 Econoline, and related truck, van, and SUV platforms listed in the fitment data. Motorad 423-195 is a practical choice when replacing a thermostat on vehicles that specify a standard 195 degree thermostat with seal.

What This Part Helps Address

• Engine running cooler or warmer than the specified operating range
• Delayed warm-up after cold starts
• Temperature fluctuation caused by a sticking thermostat
• Coolant flow control issues in OE-specified 195F systems
• Seal leakage at the thermostat housing interface

Installation Notes and Tips

Verify the housing style and temperature specification before installation. This thermostat uses a jiggle pin weep hole and includes a seal; clean the housing mating surfaces thoroughly and inspect the coolant passage for debris before assembly. The fitment data includes applications with dual thermostat housings on certain 1996 Chevrolet and GMC models, so confirm the exact engine configuration and OE requirement before ordering.
