Show original supplier description

The Honda 19301-PAA-306 Thermostat Assembly, also referred to as a Nippon Thermostat, is a genuine OEM part from Honda. This thermostat replaces a comprehensive list of previous Honda part numbers, including 19300-PT0-003, 19300-PL2-004, and 19301-PAA-305, among others. Its dimensions are 5.9 x 5.1 x 2.1 inches, and it weighs 1.10 pounds. The product is new and comes with Honda's factory warranty. Installation involves draining the cooling system, removing the radiator hose from the thermostat housing outlet, and unscrewing the housing. It is crucial to use new gaskets and O-rings and ensure the thermostat's pin is correctly oriented. Bolts should be tightened to 9 ft-lbs (12 Nm). It is cautioned against driving the vehicle without a thermostat due to potential adverse effects on emissions and fuel economy. This thermostat fits a variety of Honda models including the 1990-2002 Honda Accord, 1997-2001 Honda CR-V, 1995-1998 Honda Odyssey, and 1991-2003 Honda Civic. Specific fitment details for year, body trim, and transmission can be found in the vehicle fitment table.
