Installation Notes

Verify engine application and inlet dimensions before installation. Because the gasket or seal is not included, reuse is not recommended if the sealing surface is worn; inspect the mating surfaces carefully and replace any damaged sealing components as needed. Confirm thermostat requirements separately, since this inlet is supplied without a thermostat.
