Motorad 218-160 Engine Coolant Thermostat

Motorad 218-160 is a standard engine coolant thermostat built for precise temperature control in demanding cooling systems. It uses OEM-quality materials and OE-supplier manufacturing processes to deliver consistent coolant regulation for classic Chrysler applications, including Chrysler Newport, Town & Country, Imperial, New Yorker, and 300.

Key Features

• 160°F start-to-open temperature for controlled warm-up and stable operating temperature
• Standard thermostat design with OEM-style seals included where applicable
• Copper case and wax compound for quick response to coolant temperature changes
• Offset design with air relief valve for proper cooling-system operation
• Rubber O-ring seal included
• Sealing flange outside diameter: 2.12 in
• Height: 1.5 in; height between flanges: 1.05 in
• Flange thickness: 0.06 in

Detailed Description

This Motorad Standard thermostat is engineered for direct replacement service in older Chrysler cooling systems that require a 160°F thermostat. The copper case and wax compound are selected for fast reaction to coolant temperature shifts, helping the engine reach and maintain the intended operating range. Motorad 218-160 is a practical choice for restorations and maintenance on Chrysler Newport, Town & Country, Imperial, New Yorker, and 300 models where OE-style fit and temperature control matter.

This part cross-references Autolite 3926 and PEAK 55 for the same application. Motorad 218-160 also aligns with OE-style replacement needs for Chrysler cooling-system service.

What It Helps Address

• Engine running too cool because of a thermostat stuck open
• Slow warm-up after cold starts
• Temperature fluctuation from worn thermostat internals
• Coolant flow control issues in aging Chrysler cooling systems
• Replacement needs during cooling-system repair or restoration

Installation Notes and Tips

Install Motorad 218-160 with the sealing surface clean and free of old gasket material. Verify the housing and mating surfaces are flat before assembly, and confirm the 160°F rating matches the vehicle’s original specification. The included rubber O-ring seal should be seated evenly to prevent leaks. For Chrysler Newport, Town & Country, Imperial, New Yorker, and 300 applications, follow the service manual for coolant refill and air bleeding procedures.

Quality Assurance

Manufactured to OEM specifications and processes by an OE supplier, this thermostat is built with OEM-quality materials and safety standards. The design includes an air relief valve and OE-style sealing features where applicable to support reliable cooling-system service.
