2015 Holden Colorado exhaust gasket: what it is and when to change it

Technical sources confirm the 2015 Holden Colorado does use exhaust gaskets. The Holden Colorado RG Workshop Manual (2012–2016) details a multi‑layer steel exhaust manifold gasket, and shows sealing gaskets used at the turbo/front pipe and EGR connections. The GM Global EPC for MY2015 also lists exhaust pipe and manifold gaskets for the RG Colorado. Together, these sources make it clear an exhaust gasket is fitted and relevant on this ute.

On the Colorado, the exhaust gasket’s job is to seal hot, high‑pressure gases where components bolt together: cylinder head to manifold, turbocharger flanges, EGR cooler joints, and certain exhaust pipe flanges. A healthy seal keeps things quiet, protects the cabin from fumes, maintains turbo boost, and helps the DPF and sensors do their job properly. Some joints use a V‑band clamp with an integrated seal instead of a separate gasket
