This bulletin supersedes Dealer Technical Bulletin 88-T-71 which may be discarded. This bulletin is being revised to include the Toronado models.
Some customers may comment about the level of power steering system noise.
Some customers may comment about increased steering effort during long-duration turns and/or aggressive driving maneuvers.
Some customers may comment about both conditions.
In cases where customers have comments about power steering system noise, even after bleeding the power steering system (see new bleed procedure
below), the power steering noise condition can be corrected by installing a new reservoir, part number 26009846, available through GMSPO. This new
reservoir has increased baffling and is approximately 6 mm (.24") taller, and will prevent fluid aeration due to sloshing.

The steering effort condition can be corrected by installing a new flow control valve (called out as an O-Ring Union Fitting" in the parts catalog), part
number 7840203, available through GMSPO (see Figure 1).
