Parts for your 2008 Holden Captiva 7-Oil seals

2008 Holden Captiva 7 oil seals — what they do and when to replace them

Yes, the 2008 Holden Captiva 7 absolutely uses oil seals. Technical references including the Holden Captiva CG (2006–2011) workshop manual, GM Service Information, and the GM Global EPC parts catalogue list multiple radial lip seals across the vehicle — front and rear crankshaft seals, camshaft seals (on V6 petrol), axle/output shaft seals in the automatic transmission and transfer case, as well as differential pinion and axle tube seals. Aisin AW transmission documentation used on Captiva variants likewise specifies input/output shaft seals. So oil seals are relevant for this model.

On this Captiva, oil seals keep lubricants in and dust, water and road grime out. They’re typically spring-loaded radial lip seals made from nitrile or fluoroelastomer, designed to ride on a polished shaft surface. When they harden, wear a groove in the shaft, or face excess crankcase/gearbox pressure, they start to weep or leak.

Typical places you’ll find them on a 2008 Captiva 7 include:

• Engine: front crankshaft seal (behind crank pulley), rear main seal (at the bellhousing), and camshaft seals (V6 petrol).
• Transmission/transfer case: input and output shaft seals
