Detailed Description

Motorad 328-170 is an engine coolant thermostat made to OE quality standards for demanding cooling systems. The 170F calibration matches applications that call for this opening temperature, helping the engine reach and maintain proper operating range. Its copper case and wax compound construction are used to deliver consistent response as coolant temperature changes, while the offset design and air relief features support proper system operation where applicable. This part cross-references Anchor 3187 for the same application.

Use Motorad 328-170 when servicing Honda Civic, Honda Accord, Honda CR-V, Honda Fit, and related Acura applications that specify a 170 degree thermostat. The part number 328-170 is also a useful reference when verifying OE-style replacement needs for these cooling systems.

What It Helps Address

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant flow control after warm-up
• Temperature fluctuation caused by a sticking thermostat
• Cooling system service on Honda and Acura 170F applications
• Air trapped in the cooling circuit during thermostat replacement

Installation Notes and Tips

Confirm the OE temperature specification before installation and verify housing dimensions, including sealing flange outside diameter, height, and bypass measurements. The thermostat includes a jiggle pin weep hole, so install it in the correct orientation to help air escape from the cooling system. No gasket or seal is included, and no installation tool is included.

For best results, inspect the thermostat housing, coolant condition, and sealing surfaces before reassembly. Proper bleeding of the cooling system after service is important for stable temperature control.
