2010 Cadillac Truck SRX AWD V6-2.8L Turbo Technical Service Bulletin # 10323 Date: 101105
Recall - Power Steering Fluid Leak
SAFETY
Bulletin No.: 10323
Date: November 05, 2010
Subject: 10323 - Power Steering Fluid Leak - Replace Power Steering Line
Models:
2010 Cadillac SRX
Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2010 model year Cadillac SRX vehicles. Some of
these vehicles have a condition in which processing of the crimp during manufacture of the power steering pressure line may have damaged the
line. If the line was damaged, a power steering fluid leak may develop. If there is a sufficient amount of fluid loss, the driver will hear noise from
the power steering pump and increased effort may be required for steering. If power steering fluid sprays onto hot engine parts, an engine
compartment fire could occur.
2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 267
Correction
Dealers are to inspect (using a special gauge tool) and, if necessary, replace the power steering line on vehicles equipped with a 3.0L engine (LF1).
Due to the inability to access the power steering line with the special gauge tool on the 2.8L engine (LAU), without removing the line first, dealers
are to replace the power steering line on these vehicles.
In the event of a vehicle crash, describe seat belt event that could occur and injury to the seat occupant could occur.
Vehicles Involved
Involved are certain 2010 model year Cadillac SRX vehicles equipped with a 2.8L gas engine (LAU) or 3.0L gas engine (LF1), and built within
these VIN breakpoints:
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Required Field Actions section in the Global Warranty
system. Not all vehicles within the above breakpoints may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and
address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent
directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.
The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any purpose other than follow-up necessary to complete this recall is a violation of law in several states/provinces/countries.
Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this recall.
Parts Information
Parts required to complete this recall are to be obtained from General Motors Customer Care and Aftersales (GMCC&A). 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.
* It is estimated that very few vehicles will require the hose, P/N 20893352. Do not order parts unless the inspection procedure determines
replacement is required.
Special Tool
On October 29, 2010, each Cadillac dealer was shipped a Gauge Tool, CH-50623, for use on 3.0L (LF1) engines in this recall. This tool will be
shipped UPS-GROUND. All Cadillac dealers should have the tool no later than November 9, 2010. This tool is being furnished at no charge.
Additional tools, if required, may be purchased by contacting SPX Kent-Moore.
Courtesy Transportation - For US and Canada
The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is
covered by the New Vehicle Limited Warranties. The availability of courtesy transportation to customers whose vehicles are within the warranty
coverage period and involved in a product program is very important in maintaining customer satisfaction. Dealers are to ensure that these
customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge. Dealers
should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.

Customer Notification - For US and Canada
General Motors will notify customers of this recall on their vehicle (see copy of customer letter shown in this bulletin).
Customer Notification - For Export
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 sample letter.
Dealer Recall Responsibility - For US and Export (US States, Territories and Possessions)
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall 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 notification letters, customers are told how to contact the US National
Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
Dealer Recall Responsibility - All
All unsold new vehicles in dealers' possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall
bulletin before customers take possession of these vehicles.
Dealers are to service all vehicles subject to this recall 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. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Recall 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 recall enters your vehicle inventory, or is in your dealership for service in the future, you must take
the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.

Service Procedure
Service Procedure
Power Steering Gear Inlet Pipe/Hose Inspection/Replacement (LF1)
Special Tools
CH-50623 Gauge Tool
This procedure includes an inspection to gauge check the diameter of the hose mid crimp body. Over crimping (an undersized crimp diameter) may
have damaged the structure of the hose.
Because the crimp can be tapered (smaller diameter at one end) and oblong in shape, the gauge check must be performed at four locations around
the diameter at each end of the crimped section.
Note
An undersized crimp at just one of the eight positions is considered an unacceptable crimp
2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 269
1. Remove the intake manifold cover.
2. Remove the power steering gear inlet pipe/hose upper retaining bolt.
3. Remove the tie strap (1) and slide the mesh sleeve down the hose to expose the mid crimp.
Position #1
Position #2
2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 270
Position #3
Position #4
4. Use CH-50623 to check the crimp diameter at all 4 crimp diameter pairs at each end (identified with arrows in the above illustration) of the
crimped section. Attempt to slide the CH-50623 over the crimp at 4 different locations, working your way around the crimp for a total of 8
checks (4 checks at each end).
Note
Some undersized (unacceptable) crimp diameters near the gauge size may require the tool to be wiggled slightly for it to slide over the
crimp. Use feel, not excessive force to perform this step.
Note
The crimp diameter check must be performed on the surfaces between the crimp ridges.
Note
The illustration below shows the inspection being done on the crimp with the power steering gear inlet pipe/hose out of the vehicle for
demonstration purposes only. The procedure should be done with the power steering gear inlet pipe/hose in the vehicle.
2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 271
A - Unacceptable Crimp, B - Acceptable Crimp
1. If the CH-50623 will not slide over and bottom out against the crimp at any of the locations, the crimp checks good (is within
specifications) and no further action is required (portion B of the above illustration). Slide the mesh sleeve back into its original position
under the retaining clamp. If the mesh is frayed, it may be necessary to wrap it with tape to slide it under the clamp. Reinstall the retaining
bolt and tighten to 9Nm (80 lb in). Reinstall the intake manifold cover.
2. If the CH-50623 slides over and bottoms out against the crimp at any one of the 4 crimp diameter pairs (portion A of the above
