Manufactured by \u003cstrong\u003eCalorstat\u003c\/strong\u003e, it serves \u003cstrong\u003eMack and Volvo engine cooling systems\u003c\/strong\u003e and replaces an entire family of \u003cstrong\u003eMack\u003c\/strong\u003e numbers with one part. A thermostat is a small component that decides whether the engine warms up, holds temperature, or cooks itself: stuck shut it overheats and can take the head gasket with it, stuck open it runs cold, kills the cab heat and quietly costs you fuel every mile. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.\u003c\/p\u003e\n\n\u003ch2\u003eTemperature Under Control: The OE Engine Coolant Thermostat Advantage\u003c\/h2\u003e\n\n\u003cp\u003eEverything downstream of the thermostat depends on it being right. The water pump, the radiator, the fan clutch and the ECU's fan strategy all assume the engine reaches and holds its designed operating temperature, and a thermostat that sticks, drifts or opens lazily undermines every one of them. This is a \u003cstrong\u003eCalorstat\u003c\/strong\u003e unit built to \u003cstrong\u003eOE grade\u003c\/strong\u003e, the same class of part the engine was assembled with, rather than a discount substitute you will be back under the hood for.\u003c\/p\u003e\n\n\u003cp\u003eOne part number also covers a lot of ground here. This thermostat crosses the \u003cstrong\u003eMack 20463750 \/ 20560249 \/ 21237213 \/ 21264664 \/ 21412639\u003c\/strong\u003e family and applies across both \u003cstrong\u003eMack and Volvo\u003c\/strong\u003e engine cooling systems, which is exactly the kind of consolidation that keeps a shop shelf sane instead of stocking five near-identical boxes for the same job.\u003c\/p\u003e\n\n\u003cp\u003eAt FleetPro Parts \u0026amp; Tires, we would rather you replace the thermostat once and correctly. This unit is a direct replacement for highly searched industry numbers including \u003cstrong\u003eMack 20560249\u003c\/strong\u003e, \u003cstrong\u003e20463750\u003c\/strong\u003e, 21237213, 21264664 and 21412639. Refill and bleed the cooling system properly after the swap, because an air pocket sitting behind a new thermostat reads exactly like a bad one.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eVehicle Fitment \u0026amp; Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis OE-grade thermostat is intended for the following commercial applications:\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMake\/Model:\u003c\/strong\u003e Mack and Volvo engines\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e Engine cooling system\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNumber Family:\u003c\/strong\u003e Mack 20463750 \/ 20560249 \/ 21237213 \/ 21264664 \/ 21412639\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Group:\u003c\/strong\u003e Cooling System \/ Water Pumps \u0026amp; Thermostats\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eDirect Replacement \u0026amp; Cross-Reference Numbers:\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003eThis Calorstat engine coolant thermostat serves as a direct replacement for the following part numbers:\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMack Interchange:\u003c\/strong\u003e 20463750, 20560249, 21237213, 21264664, 21412639\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAutomann Distributor #:\u003c\/strong\u003e 840.THS18201.82\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Engine Coolant Thermostat\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mack and Volvo engine cooling systems\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOEM Reference:\u003c\/strong\u003e Mack 20560249\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e OE\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-Year FleetPro Warranty\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eProduct Level:\u003c\/strong\u003e OEM\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Calorstat (Distributed by FleetPro Parts \u0026amp; Tires)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calorstat","offers":[{"title":"Default Title","offer_id":43024030957639,"sku":"840.THS18201.82","price":29.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/8035\/2583\/files\/image_1920_b4bedf49-25ab-4f6f-9e5c-405661b89df9.jpg?v=1785427761","url":"https:\/\/fleetpropt.com\/products\/engine-coolant-thermostat-mack-volvo-engines-20560249-20463750-840-ths18201-82","provider":"FLEETPRO PARTS \u0026 TIRES","version":"1.0","type":"link"}
