REMOVAL & INSTALLATION



22R-TE

See Figures 1, 2 and 3

  1. Disconnect the negative battery cable.
  2.  
  3. Drain the coolant.
  4.  


CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

  1. Disconnect the O 2 sensor wire clamp and connector.
  2.  
  3. Disconnect the Nos. 1 and 3 PCV hoses.
  4.
