3 remove the large hose from the top of the therm houosing ,bend it down to drain, pour in the A/F untill it comes out the top,replace hose
4 remove manifold hoses from the therm housing, pour A/F in untill it comes out the exaust.
5 remove drains from "cool fuel" or P/S cooler by removing a lower hose to let drain , reinstall hose/plug.also make sure some A/f is put in the raw water pump housing
