Parts for your 2015 Honda Accord-Oil seals

2015 Honda Accord oil seals – what they do and when to replace them

Oil seals are absolutely used on the 2015 Honda Accord. Honda’s 2013–2017 Accord Service Manual and the Honda Electronic Parts Catalogue list multiple engine and transmission oil seals for this model, including the front and rear crankshaft seals, camshaft and timing cover sealing, oil pump seals, and transaxle/drive shaft oil seals. That means oil-seals are directly relevant to keeping a 2015 Accord clean, quiet, and leak‑free.

These small rings of rubber or PTFE ride on spinning shafts and around covers to keep engine or gearbox oil inside and grit and moisture out. On the 2.4-litre four-cylinder (timing chain) and the 3.5-litre V6 (timing belt), the front crank seal sits behind the crank pulley. The rear main seal lives between engine and gearbox. There are also seals at the camshafts or front cover area, plus drive shaft seals where the CV shafts enter the auto/CVT/manual transmission.

There’s no set time-based replacement for oil seals, they’re serviced on condition. During routine servicing, a good visual once-over for sweating or drips is the go. If oil is found near the crank pulley or timing cover, or around the bellhousing, a seal may be due. For the V6, it’s smart to consider front seals when doing the timing belt. For the four-cylinder, consider seals whenever the front cover is off. Rear main seals are typically done when the transmission is out for a clutch (manual) or other major work. Drive shaft seals are often replaced when axles are removed.

• Common signs a seal needs attention:
  • Fresh oil mist around the crank pulley or timing cover
  • Oil drips from the bellhousing area (rear main)
  • Oily CV housing or trans case near axle stubs
  • Burnt‑oil smell after a drive, or unexplained oil loss

Best practice is to use quality OEM-equivalent seals, lightly oil the sealing lip on install, and ensure the shaft surface is clean and smooth. Keeping crankcase ventilation (PCV) healthy prevents pressure build‑up that can push past seals. Correct installation depth and torque specs should follow the Honda service manual.

Look after the seals and they’ll quietly look after the Accord, keeping the engine bay tidy and the driveway free of spots.

Popular questions about 2015 Honda Accord oil seals

What oil seals does a 2015 Accord typically have?
A 2015 Accord commonly has a front crankshaft seal, rear main (crank) seal, camshaft/front cover sealing, oil pump seal, and drive shaft/transaxle input and output seals. Exact fittings vary slightly between the 2.4L four-cylinder and 3.5L V6, but both use crank and transaxle seals.

These are all documented in Honda’s service literature and parts catalogue for the 2013–2017 Accord range.

When should oil seals be replaced on a 2015 Accord?
Replace them when there’s visible leakage, oil contamination of belts or clutches, or when related components are off the car. For the V6, consider front seals during a timing belt service. For the four-cylinder, consider seals when the front cover is removed. Rear main and drive shaft seals are commonly replaced during gearbox or axle work.

How much does a rear main seal job cost?
Because the transmission needs to come out, labour is the big factor. As a ballpark, workshops in Australia often quote around AUD $800–$1,800, and in New Zealand roughly NZD $900–$2,200, depending on engine/trans type and what else is done at the same time. A firm estimate requires an inspection.
