Motorad 246-192 Engine Coolant Thermostat

Engine Coolant Thermostat for OE-Style Cooling Control

The Motorad Standard 246-192 engine coolant thermostat is built for precise temperature regulation in demanding cooling systems. It is a 192°F thermostat with a copper case and wax compound for quick reaction to coolant temperature changes, making it a direct-fit choice for select BMW and Rolls-Royce applications.

Compatible With 1975-1998 BMW 530i, 528i, 528e, 533i, and 320i, plus Rolls-Royce Silver Shadow II, Silver Spirit, Silver Spur, and Touring Limousine applications, this thermostat supports stable engine operating temperature in classic import cooling systems. The Motorad 246-192 is also cross-referenced to Gates 24692 and Anchor 3559 for the same application.

Detailed Description

Motorad Standard line thermostats are built for straightforward replacement service in factory-style cooling systems. Part number 246-192 uses OEM-quality materials and manufacturing processes to maintain consistent coolant flow control, helping the engine reach and hold its intended operating temperature. For BMW 530i, 528i, 528e, 533i, and 320i models, as well as Rolls-Royce Silver Shadow II, Silver Spirit, Silver Spur, and Touring Limousine vehicles, this 192°F thermostat matches the needs of higher alternate temperature replacement applications listed in the fitment data.

The copper case and wax compound are selected for fast response as coolant temperature changes, which is important in older European cooling systems that rely on accurate thermostat behavior. Part number 246-192 is a practical OE-style replacement for drivers servicing classic BMW and Rolls-Royce cooling systems.

What It Helps Address

• Engine running too cool or not reaching normal operating temperature
• Temperature fluctuation caused by a worn thermostat
• Delayed coolant flow regulation in aging cooling systems
• Replacement needs during cooling system service on classic BMW and Rolls-Royce models

Installation Notes and Tips

Verify the thermostat temperature rating and housing dimensions before installation. This unit does not include a gasket or seal, so the correct sealing component must be sourced separately. Confirm bypass diameter, bypass length, and flange dimensions against the original part when servicing BMW 530i, 528i, 528e, 533i, 320i, or Rolls-Royce Silver Spirit, Silver Spur, Silver Shadow II, and Touring Limousine applications.

Clean the thermostat housing mating surfaces before assembly and inspect the cooling system for contamination, restricted flow, or worn hoses that could affect thermostat performance.

Quality Assurance

Motorad manufactures this thermostat as an OE-supplier product using OEM-quality materials and safety standards. The Standard line is built to meet factory-style replacement expectations for demanding automotive cooling systems.
