ley (1) (if equipped).
11) With hose connected, detach P/S pump from its bracket and
then remove P/S pump bracket (2) (if equipped) referring to
“Power Steering Pump” in Section 3B1. WARNING:
To help avoid danger of being burned, do not remove
drain plug (1) and radiator cap while engine and radiator
are still hot. Scalding fluid and steam can be blown out
under pressure if plug and cap are taken off too soon.
