Dayco Thermostat DT278N Ultra-Select cracking when removing heater hoses

cracking when removing heater hoses is common

Acts as an odour barrier protecting vehicle occupants from harmful exhaust gases and noxious odours

oxidation and corrosion inhibitors and will resist "squeeze out" from surfaces requiring lubrication under load conditions

This means low particle emissions when braking

Dayco Thermostat DT278N Ultra-Select cracking when removing heater hosesDayco thermostats are designed to OEM specifications and come with a heat sensing wax filled copper power pill that detects the coolant temperature in the engine. The Dayco thermostat's amazing heat sensing power pill controls coolant flow from the radiator when the engine is cold to reach optimum operating temperature quickly. It then allows coolant to circulate through the engine when operating temperature is reached to create the perfect
