Description

Keep your heavy-duty cooling system running at the right temperature with the Motorad engine coolant thermostat 4072-90 (also written 407290). This heavy-duty thermostat controls coolant flow between the engine and radiator, staying closed until the coolant reaches its 190°F (87.78°C) start-to-open temperature so the engine warms up quickly and then holds a steady operating temperature. It drops in as a direct-fit replacement across a wide range of medium- and heavy-duty trucks and buses, including the 2000-2010 Ford F-650 and F-750 [L6-7.2L], the 2003-2008 Chevrolet C8500 [L6-7.2L], and the 2004-2010 Blue Bird Vision School Bus [L6-7.2L].

Copper case & wax compound: gives a rapid, consistent response to coolant temperature changes.
Heavy-duty construction: high-grade stainless steel and copper, built to OEM materials and standards and meeting or exceeding OEM specs.
Jiggle-pin check valve & weep hole: lets trapped air bleed off as the system is filled.
100% tested and calibrated: OE-style design for a direct-fit replacement.

Sealing flange outside diameter is 2.12 in (53.84 mm). A gasket or seal is required but is not included, so source the correct one for your application. This thermostat also fits engines including 6-8.1L, L4-4.3L, L4-4.8L, L6-6.4L, L6-6.6L, L6-7.2L and V8-8.1L across the listed applications — see the Buyer's Guide tab for the full list. Country of origin: China.
