Parts for your 2011 Nissan Pulsar-Oil seals

2011 Nissan Pulsar oil seals — what they do and when to replace

Oil seals absolutely are used on the 2011 Nissan Pulsar. Technical documentation such as the Nissan C11 series (Tiida/Pulsar) 2011 Factory Service Manual — Engine Mechanical and Transmission/Transaxle sections — specifies front and rear crankshaft oil seals, camshaft oil seals, and transaxle/differential output shaft oil seals. The Jatco RE0F10A/JF011E CVT service literature also details output shaft and input seals. So yes, the Pulsar relies on multiple oil seals to keep engine oil and transmission fluid where they belong.

On this model, oil seals are there to stop fluid escaping past spinning shafts and housings. They keep engine oil inside the timing cover and crankcase, prevent gearbox or CVT fluid from weeping at the driveshafts, and protect clutches and belts from contamination. When a seal hardens, wears a groove on the shaft, or copes with excess crankcase pressure, you’ll see tell-tales like oil mist at the crank pulley, drips at the bellhousing, or gearbox fluid around the driveshafts.

Common seals on a 2011 Pulsar include:

• Front crankshaft seal (behind the crank pulley)
• Rear main seal (between engine and transmission)
• Camshaft oil seals
• Manual/auto/CVT transaxle input and output/driveshaft seals

There’s no fixed replacement interval in Nissan’s schedules for oil seals
