## NHTSA's summary

THERE ARE OCCASIONS WHEN A LEAK MAY DEVELOP IN A PRESSURE HOSE WITH A CRIMP\-STYLE END FITTING AT THE POWER STEERING PUMP CONNECTION. THIS MAY BE DUE TO THE ORIENTATION AND LENGTH OF THE OE PRESSURE HOSE. A PRODUCT IMPROVEMENT THAT REORIENTS THE POWER STEERING PUMP AND CHANGES THE LENGTHS OF PRESSURE AS WELL AS SUCTION HOSES WAS IMPLEMENTED IN PRODUCTION ON JULY 28 2003. THIS BULLETIN PROVIDES INFORMATION TO MAKE THIS IMPROVEMENT ON EARLIER VEHICLES THAT EXPERIENCE THE LEAK DESCRIBED. \*TT
