Parts for your 2013 Holden Captiva 5-Exhaust gasket

2013 Holden Captiva 5 exhaust gasket — what it is and when to change it

Based on technical sources — the Holden/GM Service Information (CG Series II, 2013), the Holden Global EPC (Electronic Parts Catalogue), and GM Genuine/ACDelco parts listings for Captiva/Antara — the 2013 Holden Captiva 5 is fitted with exhaust gaskets. The 2.4‑litre petrol uses a multi‑layer steel gasket between the exhaust manifold and the cylinder head, plus a sealing ring (donut) at the front pipe joint. The 2.2‑litre turbo‑diesel adds turbocharger flange gaskets. These are identified as service parts in the EPC, and GM SI procedures specify replacing them whenever the joint is disturbed. So an exhaust gasket absolutely applies to this model.

On a Captiva 5, the exhaust gasket’s main job is to keep hot gases inside the exhaust, stopping that tell‑tale ticking, protecting the cabin from fumes, and keeping the oxygen sensor readings stable so the engine management can fuel properly. A sound seal also helps the cat and turbo (diesel) do their thing without stray leaks upsetting flow or temps.

There’s no fixed interval to replace exhaust gaskets as part of routine servicing of your 2013 Holden Captiva 5, they’re a “replace on condition” or “replace when removed” item. Good times to check them are during scheduled services when the car’s on a hoist. Look and listen for cold‑start ticking, a sulphury whiff, black sooty marks around flanges, or any hiss under load. If the manifold, front pipe, cat, or turbo is coming off for other work, fit new gaskets — GM SI calls most of these single‑use.

Handy workshop tips: let the system cool fully, soak manifold studs and spring bolts with penetrant, and support the exhaust to avoid stressing flex joints. Clean sealing faces gently and never use silicone sealant on exhaust joints. On refit, follow the GM torque specs and tightening sequence for the manifold, and use new spring bolts or copper‑coated nuts where specified. After a heat cycle, a quick re‑check for leaks is smart, even though modern MLS gaskets generally don’t need re‑torquing.

If it’s leaking, don’t put it off. Apart from noise and fumes, leaks can skew O2 sensor data, hurt fuel economy, and on the diesel, impact turbo performance. Quality OEM or reputable aftermarket gaskets are the go for a lasting fix.

Does the 2013 Captiva 5 use sealant instead of an exhaust gasket?

No. Technical procedures in GM SI specify solid gaskets (MLS at the manifold, crush ring at the front pipe) and do not call for RTV or paste. Using sealant on these joints can burn off and contaminate sensors.

How much does it cost to replace an exhaust gasket on a Captiva 5?

Ballpark in Aus/NZ: a front pipe donut gasket job might land around $150–$350 fitted. A manifold gasket can run $350–$800+ depending on engine, stud condition, and access. Rusted hardware or turbo‑diesel flange gaskets can add time and parts.

Is it OK to drive with a leaking exhaust gasket?

Short term, it might get you home, but it’s not ideal. You risk fumes entering the cabin, skewed sensor readings, poor economy, and on diesels, turbo efficiency losses. Best to sort it sooner rather than later.
