How to Replace an Oil Pump in a Toyota Camry

How to Replace an Oil Pump in a Toyota Camry

Losing lubrication in an engine will destroy it. The oil pump makes sure this doesn't happen by cycling oil through the engine and keeping it lubricated. In most cases, the oil pump lasts through the lifetime of a car, but if there is an accident or if an engine needs overhauling, the oil pump in the Toyota Camry sometimes needs to be replaced.

Difficulty:
Moderately Challenging

Instructions

things you'll need:

  • Ramps or lifts
  • Pan for drained fluids
  • Wrench
  • Rag for cleaning
  • New oil pump
  • New O-ring
  • Fresh engine oil
  1. Remove Oil Pump

    • 1

      Drive your Toyota Camry up onto ramps or lifts so you have room to work as you pull out the oil pump. You could also use a jack, but make sure you brace the front wheels so they don't roll. In addition, set the emergency break firmly into position so the car doesn't roll.

      Drain the oil out of your engine and disconnect the negative battery cable. Remove the fender apron seal and the undercover, the front exhaust pipe, and the front exhaust pipe bracket from the No. 1 oil pan.

      Remove the following components in order: the alternator drive belt, the air conditioner compressor, the power steering pump drive belt and the adjusting strut, the timing belt along with the belt pulleys, the rear timing belt cover, the air conditioning compressor housing bracket, the No. 2 oil pan and oil strainer, as well as the No. 1 oil pan and baffle plate.
