Motorad 242-170 Engine Coolant Thermostat

Engine Coolant Thermostat for OE-Style Cooling Control

Motorad Standard 242-170 is a 170°F engine coolant thermostat built for OE-style temperature control in demanding cooling systems. It uses OEM-quality materials and manufacturing processes, with a copper case and wax compound for responsive coolant temperature regulation.

Compatible With select Honda Civic, Accord, CR-V, Prelude, CRX, Acura Integra, CL, Legend, Isuzu Oasis, Ford Transit, and Toyota Pickup applications, this thermostat is a direct-fit service part for vehicles that require a 170°F opening temperature. The Motorad 242-170 also includes an offset design, air relief valve, and OEM-style seals where applicable.

Key Features

• 170°F start-to-open temperature for OE-specified cooling performance
• Copper case and wax compound for quick reaction to coolant temperature changes
• Jiggle pin weep hole for air relief during cooling system service
• Offset design for application-specific fitment
• Standard Motorad line construction for routine replacement service
• Part number 242-170 for easy catalog matching

Detailed Product Information

Motorad Standard 242-170 is engineered as an OE supplier thermostat using OEM specifications and processes. The 2.04 in sealing flange outside diameter, 1.51 in height between flanges, 2.15 in overall height, and 0.05 in flange thickness support proper housing fitment where specified. The bypass measures 1.09 in in diameter and 1.37 in in length. This thermostat does not include a gasket or seal, and no installation tool is included.

This part cross-references Gates 24270 for the same application. It is a practical replacement choice for drivers servicing Honda Civic and Acura Integra cooling systems, as well as other listed applications that call for a 170°F thermostat. Use Motorad 242-170 when restoring stable engine operating temperature and consistent coolant flow control.

What This Thermostat Helps Address

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant circulation after cold starts
• Temperature fluctuation from a sticking thermostat
• Air trapped in the cooling system during service
• Loss of OE-specified 170°F temperature control

Installation Notes and Tips

Verify the housing style, bypass dimensions, and 170°F temperature requirement before installation. Because no gasket or seal is included, reuse only if serviceable or replace with the correct sealing component for the application. Inspect the cooling system for contamination, flush if needed, and confirm proper coolant level after installation. The jiggle pin weep hole should be oriented according to the vehicle service procedure to help purge trapped air.

Quality Assurance

Motorad manufactures this thermostat with OEM-quality materials and OE-supplier processes to meet standard cooling system requirements. The copper case, wax element, and OEM-style design details are selected to support consistent temperature regulation in the listed applications.
