Need a new oil pump for your Toyota or Pontiac? This DNJ replacement is a solid, brand-new part that fits a bunch of models from 2000 to 2006: the Pontiac Vibe, Toyota Corolla, Matrix, and Celica with the 1.8L 4-cylinder DOHC engine (that's the 2ZZ-GE engine code, if you're into specifics). It's a direct replacement for part number M387. DNJ is a trusted brand with over 30 years in the engine parts game, so you know you're getting decent quality. It comes with a 1-year or 12,000-mile limited warranty (whichever comes first), which gives you some peace of mind. Installing a new oil pump is serious business – it's the heart of your engine's lubrication system. If yours is worn out or failing, you'll want to swap it out before it causes bigger (and way more expensive) problems. This is for the DIY mechanic who's comfortable with engine work or for a professional shop job. Just make sure it matches your exact vehicle and engine before you order. Keep that 2ZZ-GE running strong!
