Parts for your 2013 Holden Captiva 5-Oil seals

2013 Holden Captiva 5 oil-seals — what they do and when to replace them

Oil seals are absolutely relevant and used on the 2013 Holden Captiva 5. Technical references such as GM Global Service Information (engine, transaxle and driveline sections for Captiva/Antara), the GM Electronic Parts Catalogue for Captiva 5 (CG Series), and aftermarket catalogues from ACDelco, Timken/National and Corteco list multiple oil seals for this model, including the front crankshaft seal, rear main seal, camshaft seals (where applicable), and transaxle output/axle shaft seals. That confirms they’re fitted as standard components on the vehicle.

On a Captiva 5, oil seals keep engine and transmission fluids where they belong while keeping grit and moisture out. Up front, the crank seal sits behind the harmonic balancer, stopping engine oil from weeping past the crank. At the opposite end, the rear main seal keeps oil inside the engine where it mates to the gearbox. The transaxle has output shaft seals around the driveshafts to prevent gear oil or ATF leaks. Where fitted, camshaft seals do similar duty around the cam sprockets.

They’re not a scheduled “replace-by” item, but they are critical. During regular servicing, a good workshop will quickly scan for tell-tales: oil misting near the crank pulley, drips from the bellhousing, or a damp patch around a driveshaft. If a seal is sweating or leaking, address it sooner rather than later. Running low on oil or ATF can escalate into big-ticket repairs.

Best practice on this model is to:

• Inspect at every service for fresh oil tracks, undertray wetness, or dust stuck to oily areas.
• Replace seals on condition, or proactively when related parts are off (e.g., during timing/front cover work, clutch/torque converter access, or when a CV shaft is removed).
• Use quality OEM-equivalent seals and the correct fluids (Dexron-VI ATF for the 6-speed auto, check VIN-specific specs for manual/engine variants).
• Check crankcase ventilation (PCV) function, excess crankcase pressure can push new seals out.
• Install with proper drivers, inspect the sealing surface on the shaft, and set to the correct depth.

Common symptoms that point to oil-seal attention on a Captiva 5 include a burning oil smell after a drive, spots under the car, oil around the harmonic balancer, or gearbox oil weeping where the driveshaft enters the transaxle. Quick diagnosis and the right parts keep the Captiva tidy under the bonnet and on the driveway.

Popular questions

Are oil seals used on the 2013 Holden Captiva 5, and where are they located?
Yes. This model uses multiple oil seals, including the front crankshaft seal, rear main seal between the engine and gearbox, and transaxle output shaft (driveshaft) seals. Depending on engine variant, camshaft seals may also be present. These seals are documented in GM service procedures and parts catalogues for the Captiva/Antara platform.

How can someone tell if the rear main seal is leaking on a Captiva 5?
Look for oil collecting at the join between the engine and transmission, drips from the bellhousing area, or an oily undertray. On manuals, a severe leak can contaminate the clutch. Because other leaks can mimic a rear main, a UV dye test and a careful clean-and-recheck is the smart way to confirm before replacing anything.

Should both transaxle output seals be replaced when doing a CV shaft?
It’s not mandatory, but it’s good practice to replace a hard or nicked seal while access is open. If the vehicle has higher kilometres or there’s any sign of weeping, renewing the relevant output seal (and topping up with the correct fluid) helps prevent a comeback. Always inspect the driveshaft journal for wear before refitting.
