Compressed Natural Gas Leak Test: Notes
WARNING: This page is about a different variant/trim than selected.
NOTE:
After vehicle has hot-soaked for several hours, a very slight natural gas smell may emanate from within intake manifold and intake air system. This is normal, as fuel injectors leak down from fuel injection supply manifold to intake manifold over several hours. Follow all safety precautions. See FUEL SYSTEM SAFETY PRECAUTIONS and/or CNG/LPG SAFETY PRECAUTIONS article in GENERAL INFORMATION.
