Leak test
Check condition: The engine is cold or slightly warm.
1. Start the engine and, with the engine running, plug the exhaust pipe with a rag.
2. Have an assistant inspect all joints and check by ear or touch for possible exhaust fumes (hissing hot air). If necessary, apply leak detection spray to exhaust manifold, downpipe, turbocharger connections. Make sure that no air bubbles are formed in the indicated places.
3. Repair any leaks found.
