DESCRIPTION
Some 1987 RX-7 vehicles equipped with air conditioning systems may encounter a buzzing noise caused by the suction side of the A/C flexible hose
vibrating against the firewall.
When this condition occurs, check the retaining clamp (0000-67-A43A-6A) to see if it has lost its crimping ability. If it has, it can be easily corrected by
following the steps below:
1.
Loosen nut securing the clamp to the hose bracket.
2.
Crimp the clamp as shown in the illustration.
3.
Retighten nut.
This will give the clamp better crimping ability.
