Installation and maintenance guidance

To ensure proper installation and prevent system leaks, technicians should inspect the valve housing for any debris or scoring before assembly. Using high-strength components during the overhaul process helps maintain the integrity of the exhaust system under high thermal loads. Check the compatibility list to confirm fitment.
