Description

Hold your engine at its correct operating temperature with the MotoRad Engine Coolant Thermostat MRD105. It installs as a direct-fit replacement for a wide list of GM, Isuzu, Saab and Mitsubishi Fuso applications, including the 2007 Buick Rainier, 2009-2014 Cadillac CTS, 2010-2015 Chevrolet Camaro, 2007-2013 Chevrolet Silverado 1500, 2007-2023 GMC Sierra 2500 HD, 2008-2010 Hummer H3, 2007-2018 Isuzu NPR and 2008-2009 Saab 9-7X — see the Buyer's Guide tab for the full list of 78 applications.

Temperature-controlled valve: stays closed during warm-up, then opens as the coolant reaches operating temperature to route flow to the radiator.
Stable circulation: helps the cooling system hold a consistent operating temperature during normal driving.
Direct-fit replacement: serves as a coolant thermostat for the listed applications.

The thermostat is the valve between the engine and the radiator: it restricts coolant flow until the engine warms up, then opens to let coolant circulate and shed heat. Signs it may need replacing include the engine overheating, running colder than normal, weak cabin heat, or temperature readings that swing. Diagnose the cause first; if a failed thermostat is behind the symptom, this replaces it.

Frequently Asked Questions

What does this thermostat do?

It regulates coolant flow between the engine and radiator, staying closed during warm-up and opening as the coolant reaches operating temperature so the engine holds a stable temperature.

Will the MRD105 fit my vehicle?

It's a direct-fit replacement for 78 listed applications, including many Chevrolet, GMC, Cadillac, Hummer, Isuzu, Saab and Mitsubishi Fuso models. Check the Buyer's Guide tab to confirm your year, make, model and engine.

What are signs my thermostat may need replacing?

Common signs include engine overheating, running colder than normal, weak cabin heat, or temperature-gauge readings that fluctuate. Diagnose the cause before replacing.

Is a gasket or seal included?

The listed facts don't specify included hardware. Consult the vehicle service information for the correct gasket or seal and any required fasteners before installing.

Can a bad thermostat cause overheating?

A thermostat stuck closed can restrict coolant flow and contribute to overheating, but overheating has other causes too. Diagnose the system first; if the thermostat is the cause, this replaces it.
