2015 Holden Captiva 7 head-gasket: purpose, care, and when to replace

Technical sources confirm the 2015 Holden Captiva 7 absolutely uses a head-gasket. The Holden Captiva CG Series II Service Manual (GM Service Information) includes “Engine Mechanical — Cylinder Head Gasket Replacement” procedures, and the Holden/GM Electronic Parts Catalogue and ACDelco parts catalogues list head-gaskets for all engines fitted to this model year — the 2.4‑litre petrol four, 3.0‑litre V6 petrol, and 2.2‑litre turbo‑diesel. That means a conventional multi‑layer steel (MLS) head-gasket is part of the engine build on every 2015 Captiva 7.

On a 2015 Captiva 7, the head-gasket sits between the cylinder head and block, sealing combustion pressure while keeping engine oil and coolant in their own passages. It’s the quiet achiever that lets the engine make proper compression without cross‑leaks, holds back combustion gases, and stops coolant and oil from mingling. The factory gasket is MLS, chosen for durability and heat‑cycling tolerance, especially important in Aussie and Kiwi conditions where towing, traffic, and hot summers can push cooling systems hard.

There’s no routine “service interval” for a head-gasket
