FAQ
Do I need sealant with this gasket?
Many thermostat housing gaskets install dry, but requirements can vary by housing condition and manufacturer guidance. Follow PCM/service manual recommendations.
Should I replace the thermostat at the same time?
If the thermostat is old, corroded, or you’re already disassembling the housing, replacing it during service can help prevent repeat labor later.
