DATE: January, 2003
MODEL: 1997-02 Montero Sport
SUBJECT:
A/C PULSATING / RATTLE NOISE
PURPOSE
A pulsating or rattle noise may be heard when the A/C is on. This bulletin describes how to eliminate the noise.
On 1997-2000 models built before 6/00, a rattle noise may be heard when the A/C is on, due to the A/C discharge hose bracket vibrating at the engine
block. To eliminate this noise, remove the A/C discharge hose bracket as described in Step 1 of this bulletin.
On 1998-2001 models built after 12/97, a pulsating noise may be heard when the A/C is on, due to A/C compressor bracket vibration. To eliminate this
noise, install the cast-iron A/C compressor bracket listed in this bulletin. This bracket has an extra mounting location to help reduce vibration. Follow the
procedure in Step 2 of this bulletin.
On 2000-2002 models, a new, improved A/C discharge hose is available to eliminate the noise. Go to Step 3 of this bulletin.
