Good To Know

Q: Does this housing come with a thermostat? A: This listing covers the thermostat housing itself; the thermostat is typically installed into the housing during service. Check whether your thermostat is being reused or replaced before ordering.

Q: Why choose aluminum over the factory housing? A: Aluminum resists the cracking and warping that plastic housings often develop over years of heat cycling. That makes it a durable option for long-term cooling system reliability.
