REMOVAL & INSTALLATION




CAUTION
When draining coolant, keep in mind that cats and dogs are attracted by 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 coolant into a sealable container. Coolant may be reused unless it is contaminated or several years old.

22R and 22R-E Engines

See Figures 1 through 5

  1. Discharge the A/C system using an approved recovery/recycling machine. Refer to General Information & Maintenance .

Fig. Fig. 1: Loosen the petcock and allow the coolant to drain into a suitable container


CAUTION
Never remove the pressure cap while the engine is running or personal injury from scalding hot coolant or steam may result. If possible, wait until the engine has cooled to remove the pressure cap. If this is not possible, wrap a thick cloth around the pressure cap and turn it slowly to the stop. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, still using the cloth, turn and remove the cap.

  1. Remove the engine undercover.
