Parts for your 2013 Holden Colorado-Oil seals

2013 Holden Colorado oil seals — what they do and when to service them

Referencing the Holden Colorado RG (2012–2016) Service Manual (GM SI) and GM/Holden parts catalogues for the RG series, the 2013 Holden Colorado is fitted with multiple oil seals throughout the engine, gearbox, transfer case and differentials. That means “oil-seals” are absolutely relevant on this model.

On a Colorado ute, oil seals keep lubricants in and grit, water and dust out, while allowing rotating shafts to spin freely. They’re typically rubber or Viton lip seals that ride on a smooth shaft surface with a light spring tension. When they’re healthy, oil stays where it should, components run cooler and last longer, and there’s less mess under the vehicle.

Common oil seals on a 2013 Holden Colorado include:

• Engine front crankshaft seal and rear main seal
• Camshaft and timing cover seals (diesel variants)
• Manual gearbox input/output shaft seals or auto transmission output seal
• Transfer case input/output shaft seals (4x4)
• Front and rear differential pinion and axle seals

There’s no fixed replacement interval for oil seals
