Parts for your 2007 Toyota Prius-Oil seals

2007 Toyota Prius oil seals — what they do and when to replace them

Oil seals are absolutely relevant to a 2007 Toyota Prius (NHW20). Toyota’s 2004–2009 Prius Repair Manual (Engine Mechanical and Hybrid Transaxle sections, often cited as RM12 series) includes procedures for the crankshaft oil seal, camshaft oil seal and hybrid transaxle drive shaft oil seals. The Toyota Electronic Parts Catalog for NHW20 also lists front and rear crankshaft oil seals and transaxle output shaft seals. Independent workshop guides (e.g., Haynes for 2001–2015 Prius) cover the same components, confirming these seals are fitted and serviceable on this model.

On a 2007 Prius, oil seals keep vital fluids in and grit out, protecting the 1NZ‑FXE engine and the P112 hybrid transaxle. They’re small, but they do a big job: holding engine oil behind the crank and cam ends, and keeping Toyota WS fluid inside the transaxle where the driveshafts exit. When they harden or wear, leaks start, and that’s the cue to act.

There’s no fixed replacement interval for oil seals on this Prius
