For 1990-2009 cars

# LOWER RAD. HOSE RUBS THROUGH ON RIGHT FRONT ENGINE MOUNT

#### SUBJECT: LOWER RADIATOR HOSE RUB THROUGH AT RIGHT FRONT ENGINE MOUNT (REPLACE HOSE ASSEMBLY)

#### MODELS AFFECTED: 1990-91 SKYLARK MODELS WITH 2.5L ENGINES (VIN CODE "U")

Some 1990-91 Skylark models equipped with a 2.5L (VIN U) engine may experience a rub through at a point where the lower radiator hose routes by the right front engine mount. If conditions are right, the hose will contact one of the bolt heads on the mount causing a rub through. This may result in a loss of engine coolant.

To correct this condition, replace hose assembly with a 1989 production style hose. This hose is formed differently and does not come in contact with the mount bolt. (Refer to Illustrations for differences).

This replacement of the lower hose must be done any time a rub through leak is noted. It is also suggested that it be replaced if any contact is seen during routine service.

Parts in stock at GMSPO will be replaced with 1989 production style hoses.

Current (1990-91) 22551441 (DO NOT USE)

Replaced by (1989) 22538799 (FOR USE IN 1989-91 APPLICATIONS)

Parts are currently available from GMSPO.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
