Parts for your 2003 Nissan Primera-Oil seals

2003 Nissan Primera oil-seals: what they do and when to sort them

Oil-seals are absolutely used on the 2003 Nissan Primera (P12). Technical references including the Nissan Primera P12 Factory Service Manual (Engine Mechanical, Manual/Auto Transmission and Front Axle sections), the Nissan FAST parts catalogue, and the Haynes Nissan Primera 1999–2006 Workshop Manual all list front and rear crankshaft oil-seals, camshaft oil-seals, and transaxle/differential side oil-seals for the P12 petrol and diesel variants.

On this Primera, oil-seals are the tidy little rings that keep engine and gearbox oil where it belongs. They sit around spinning shafts and in housings, holding pressure and blocking grime. Over time, heat, age and slight shaft wear can harden a seal’s lip, and that’s when the drips start.

Common seals on the 2003 Primera include:

• Front and rear crankshaft oil-seals
• Camshaft oil-seals
• Transaxle/differential side (drive-shaft) oil-seals
• Transmission input/output shaft seals (manual and auto)

There’s no fixed service interval for oil-seals on the P12
