Product Safety 00028 - Power Steering Cooler Hose Separation. GMC Truck Export Savana 2000

For 1990-2009 cars

# Product Safety 00028 - Power Steering Cooler Hose Separation

Subject: | 00028 -- Power Steering Cooler Hose Separation

Models: | 1999-2000 Chevrolet and GMC G-Vans

### Condition

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1999-2000 G vans equipped with a brake warning indicator (UJ1). Some of these vehicles have a power steering cooler hose that can separate from the power brake booster fluid flow switch assembly. If this occurs, power steering fluid could flow onto hot engine parts and an engine compartment fire could occur.

### Correction

Dealers are to inspect the power steering hose joints for spring clamps. If spring clamps are found, they are to be replaced with three new screw clamps.

### Vehicles Involved

Involved are certain 1999-2000 Chevrolet and GMC G vans equipped with a brake warning indicator (UJ1) and built within these VIN breakpoints:

Year | Division | Model | Plant | From | Through
--- | --- | --- | --- | --- | ---
1999 | GMC | G Van | Wentzville | X1010304 | X1162022
2000 | GMC | G Van | Wentzville | Y1100115 | Y1195240
1999 | Chevrolet | G Van | Wentzville | X1000039 | X1161723
2000 | Chevrolet | G Van | Wentzville | Y1100289 | Y1210313

Important: Dealers should confirm vehicle eligibility through VISS (Vehicle Information Service System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC Only) before beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved.]

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

### Parts Information

Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.

Part Number | Description | Qty/ Vehicle
--- | --- | ---
15620999 | Clamp | 3 (if required)

### Service Procedure

1. Raise the hood.
2. Inspect for the type of clamp used on the hoses for the fluid flow switch (Figure 1, Item 2), located directly behind the steering intermediate shaft assembly.

• | If the clamps are screw clamps, no further action is required. Install the GM Campaign Identification Label.

• | If the clamps are NOT screw clamp, proceed to Step 3.

3. Disconnect and remove the air cleaner and duct assembly.

Important: Care must be taken when relocating the existing spring clamps to ensure that the hoses are not rotated, twisted, or stretched in any way that may change the position of the hose in relationship to the power steering pump fitting or the fittings on the fluid flow switch. DO NOT DISCONNECT THE HOSES.

4. Carefully expand and position the existing spring clamps (1) on the hoses as shown in Figure 1.
5. Completely unscrew the three new clamps (2) and install them onto the hoses where the original spring clamps were located.
6. With the new clamps (2) positioned 4 mm (5/32 in) from the end of the hose joint at which they were installed, tighten the clamps.

Tighten
Tighten the clamps to 2 N·m (18 lb in).

7. Ensure that the electrical wiring harness connector is properly seated on the fluid flow switch and that the wire harness is not in contact with the hose clamps.
8. Install and connect the air cleaner and duct assembly.
9. With the engine running just off idle, the transmission in Park, and the service brake applied, complete a full right and full left turn until the end stop is reached. REPEAT THIS STEP THREE TIMES. TURN ENGINE OFF.
10. Inspect for proper hose and clamp positions and for possible leaks. Correct any leaks as required.
11. Install the GM Campaign Identification Label.

### Customer Notification

FOR US AND CANADA

Customers will be notified of this campaign on their vehicles by General Motors (see copy of customer letter included with this bulletin).

### Customer Notification

FOR IPC

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act. For owners outside these areas, dealers should notify customers using the attached suggested dealer letter.

### Dealer Campaign Responsibility

FOR US AND IPC (US States, Territories, and Possessions)

The US National Traffic and Motor Vehicle Safety Act provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall campaign notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the campaign is not completed within a reasonable time.

### Dealer Campaign Responsibility

FOR ALL

All unsold new vehicles in dealers' possession and subject to this campaign MUST be held and inspected/repaired per the service procedure of this campaign bulletin BEFORE customers take possession of these vehicles.

Dealers are to service all vehicles subject to this campaign at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers a copy of the customer letter accompanying this bulletin. Campaign follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this campaign enters your vehicle inventory, or is in your dealership for service in the future, please take the steps necessary to be sure the campaign correction has been made before selling or releasing the vehicle.

April, 2000

Dear General Motors Customer:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

### Reason For This Recall

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1999-2000 Chevrolet Express and GMC Savana vans equipped with a brake warning indicator. Some of these vehicles have a power steering cooler hose that can separate from the power brake booster fluid flow switch assembly. If this occurs, power steering fluid could flow onto hot engine parts and an engine compartment fire could occur.

### What Will Be Done

To prevent the possibility of this condition occurring, your GM dealer will inspect the power steering hose joints for spring clamps. If spring clamps are found, they will be replaced with three new screw clamps. This service will be performed for you at no charge .

### How Long Will The Repair Take?

The length of time required to perform this inspection and service correction, if necessary, is approximately 15-25 minutes. Additional time may be required to schedule and process your vehicle. If your dealer has a large number of vehicles awaiting service, this additional time may be significant. Please ask your dealer if you wish to know how much additional time will be needed to schedule, process and repair your vehicle.
