Some 1991 Bravadas may exhibit insufficient cooling in high ambient temperatures. To address this condition two service modifications have been
developed.
1.
Installation of a coolant shut off valve which actuates in A/C Max mode and an insulated cover for the accumulator.
2.
Installation of an under body shield (P/N 15564769) to improve cooling and direct air flow through the condenser.
