MotoRad Cooling Solutions

A Cooling System Specialist Focused on Small Parts With Big Jobs

Motorad is an aftermarket manufacturer known for thermostats and closely related cooling and sealing components. It's a brand many parts advisors point to when a vehicle is running cold, overheating, or throwing a thermostat-related code and the fix calls for a precise replacement rather than a guess.

Thermostats, Housings, and Caps From Motorad

Motorad's catalog focuses on parts that control temperature and pressure or seal off a system. Shoppers typically find:

Thermostats and thermostat gaskets in a range of opening temperatures, found in thermostats and parts
Thermostat housings and water outlets, including assemblies with an integrated thermostat
Radiator caps and coolant reservoir caps under radiator parts
Fuel caps and oil filler caps

Common reasons to shop this brand include a slow-warming heater, a temperature gauge that climbs, coolant seeping from a cracked plastic housing, or an evaporative emissions code tied to a worn fuel cap seal.

Why Small Cooling Parts Deserve Quality Attention

A thermostat stuck open can reduce heater output and fuel economy, while one stuck closed can lead to overheating. A weak radiator cap may let coolant boil over at lower temperatures than intended. Quality aftermarket replacements give owners an alternative to OEM parts that is built to the application's specified temperature or pressure. OEM parts guarantee the original design, while aftermarket options may offer choices like fail-safe designs or upgraded housing materials, so compare the product details.

Keep in mind that a thermostat is inexpensive compared to the damage overheating can cause. If coolant is old, contaminated, or the wrong type, a new thermostat may not solve the root problem, so it's worth checking coolant condition and looking for leaks before assuming the thermostat alone is to blame.

Choosing the Right Motorad Thermostat or Cap

Match the opening temperature or pressure rating to your vehicle's specification, not a guess. Many modern engines are designed around a specific thermostat temperature, and a different rating can affect engine management. If the housing is plastic and showing cracks or seepage, replacing the housing along with the thermostat is often the practical choice. While the system is drained, many owners also inspect hoses and clamps and the water pump.

Confirming Motorad Fitment by Engine

Thermostat and housing designs can differ by engine size and production year within the same model. Select your vehicle, check the part number, and review product fitment notes before ordering. Your VIN helps confirm the engine, and your Owner's Manual lists the correct coolant type and refill procedure.
