A thermostat stuck closed overheats the engine; stuck open it runs cold and sluggish, and a tired cap or hose lets the system leak or lose pressure. Fresh OE-spec cooling parts restore correct temperature control and a sealed, pressurized system.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ethe correct thermostat, cap or hose as specified\u003c\/li\u003e\n\u003cli\u003erelated cooling gaskets and seals where applicable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the 3.0L Duramax diesel engine, 2020-2025.
