Parts for your 2009 Toyota Blade-Oil seals

2009 Toyota Blade oil seals — what they do and how to look after them

Oil seals are absolutely used on the 2009 Toyota Blade. Factory technical information confirms it: Toyota’s service manuals (TIS) for the E150-series Auris/Blade and the Toyota Electronic Parts Catalogue list multiple seals, including the crankshaft front and rear oil seals, camshaft seals, oil pump seal, and the transaxle/differential side oil seals for both AZE156H (2AZ‑FE 2.4L with CVT) and GRE156H (2GR‑FE 3.5L with the U660E 6‑speed auto). Those sources outline inspection and replacement procedures such as “Crankshaft Oil Seal Replacement” and “Differential Side Oil Seal Replacement,” which makes the part very much relevant to this model year Blade.

On this car, oil seals keep engine oil and transmission fluid where they belong, protect bearings and clutch packs, and keep dust and water out. They also help maintain correct oil pressure around the crank and cams. The Blade’s 2AZ‑FE and 2GR‑FE engines run timing chains, so you’ll commonly find seals at the crank nose behind the harmonic balancer, at the rear main where the crank meets the flywheel/flexplate, and around the camshafts. The CVT (2.4L) and the U660E auto (3.5L) use side seals where the drive shafts enter the transaxle.

As part of servicing a 2009 Toyota Blade, oil seals are replaced on condition rather than on a fixed interval. A good workshop will inspect for weeping around the front crank pulley, timing cover edges, the bellhousing seam (rear main area), and at the driveshafts where they enter the gearbox. Any oil spotting on the undertray, wetness around the axle stubs, or burnt‑oil smell after a drive is a nudge to investigate. If the transmission or harmonic balancer is coming off for any reason, it’s smart money to refresh nearby seals while access is easy.

Quality matters. Use genuine or OE‑equivalent seals with the correct lip design and material (typically NBR or Viton). Lightly oil the sealing lip, press the seal square with a proper driver or sleeve, and check the crankcase ventilation (PCV) system so excess pressure doesn’t force a new seal to leak. For transaxle side seals, confirm the fluid spec: Toyota CVT Fluid TC/FE for the Super CVT‑i, and Toyota WS ATF for the U660E. After refit, set fluid level with the factory temperature procedure.

• Common signs of a leaking oil seal: fresh oil mist near the pulley or bellhousing, drops on the driveway, oily residue on the lower crossmember, or fluid around an axle stub.
• Left unchecked, leaks can degrade rubber mounts and belts, swell bushes, contaminate clutch linings (if manual swap), or drop fluid level enough to risk engine or transmission damage.
• During regular services, ask for a torch‑on check of seal areas and for any slight weeps to be monitored. Fix small leaks early to save bigger bills later.

FAQs

Where are the oil seals on a 2009 Toyota Blade?

They’re at key rotating interfaces: front and rear crankshaft seals, camshaft seals, oil pump seal, and the transaxle/differential side seals where the driveshafts enter the CVT (2.4L) or U660E auto (3.5L). Technicians also watch the timing cover perimeter and the sump join for sealer‑related weeps that can look like a seal leak.

What are the tell‑tale signs an oil seal is leaking on a Blade?

Fresh oil around the harmonic balancer, dampness at the bellhousing, wetness at an axle stub, oil spots on the undertray, or a faint burnt‑oil smell after parking. A drop in engine oil or transmission fluid level between services is another giveaway.

Which fluid goes back in after changing a transaxle side oil seal?

Use Toyota CVT Fluid TC/FE for the Super CVT‑i on the 2AZ‑FE, and Toyota WS ATF for the U660E on the 2GR‑FE Blade Master. Set level using the factory temperature method and a clean fill process.
