Safety Recall:
2004-08 TL Power Steering Feed Hose Leak
(Supersedes 08-016, dated March 20, 2009, to revise the information marked by the black bars and asterisks)
REVISION SUMMARY
*Under REPAIR PROCEDURE, steps 15, 23, and 44 were changed.*
BACKGROUND
Prolonged high under-hood temperatures may cause the power steering hose to deteriorate prematurely and may cause the hose to crack and leak power steering fluid. Power steering fluid leaking onto a hot catalytic converter will generate smoke and could lead to an under-hood fire.
CLIENT NOTIFICATION
Owners of affected vehicles will begin receiving notifications of this campaign the last week of April 2008. An example of the client notification letter is at the end of this service bulletin.
To verify vehicle eligibility, check at least one of these items:
^ The client has a notification letter.
^ The vehicle is shown as eligible on a VIN status inquiry.
In addition, check for a punch mark above the first character of the engine compartment VIN. A punch mark in that location means this campaign has already been completed.
Some vehicles affected by this campaign may be in your new or used vehicle inventory. If a repair kit is not available for a new TL, it may be sold or leased with the understanding that it must be returned for campaign completion at a later date. If a repair kit is not available for a used TL, it should be fitted with a current P/S feed hose before it is sold or leased. Like the new TLs, used TLs fitted with a current P/S feed hose must be returned for campaign completion at a later date. To see if a vehicle is affected by this campaign, do a VIN status inquiry before selling or leasing it.
CORRECTIVE ACTION
Install a power steering feed hose kit.

REPAIR PROCEDURE
1. Remove the engine compartment covers shown below.
2. Drain the P/S fluid:
NOTE:
Take care not to spill any fluid. Wipe off any spilled fluid immediately.
^ Refer to page 17-13 of the 07-08 TL Service Manual, or
^ Online, enter keywords STEERING FLUID, and select Power Steering Fluid Check/Replacement from the list.
3. Check the condition of the drained fluid:
^ If the fluid is contaminated, dark, or discolored, discard it; do not reuse it.
^ If the fluid is clear with no contamination, save it in a covered container. It will be reused in step 46.
4. Reinstall the return hose on the P/S reservoir. If the hose clamp on the return hose is damaged, replace it.
5. Remove the two bolts from the under-hood fusel relay box, then detach the fuse/relay box from the strut brace bracket.
6. Remove the two bolts from the throttle cable bracket, then detach the clip from the strut brace.
7. Remove the strut brace:
^ Remove the harness clamp.
^ Remove the two bolts. Remove the six nuts.
8. Disconnect the P/S feed hose from the steering gearbox by loosening its flare nut.
NOTE:
To prevent fluid from dripping, place several shop towels under the feed hose connection, and wrap a towel around the exposed joint end.
9. Remove the end of the P/S feed hose from the P/S pump.
NOTE:
To prevent fluid from dripping, wrap a towel around the exposed end of the hose.
10. Replace the P/S pump inlet joint 0-ring:
^ Remove the inlet joint from the pump (one bolt).
^ Remove the 0-ring from the inlet joint.
^ Lubricate a new 0-ring with clean P/S fluid, then install it on the end of the joint.
^ Reinstall the inlet joint, and torque its bolt to 11 Nm (8 lb.ft).
11. Remove the feed hose bracket from the valve cover (one bolt).
12. Disconnect the P/S pressure switch connector, then remove the pressure switch from the feed hose.
NOTE:
To prevent fluid from dripping, stuff the end of a clean shop towel into the feed hose coupler.
13. Remove the 0-ring from the P/S pressure switch and install a new one, lubricated with clean P/S fluid.
14. Install the original P/S pressure switch on the new feed hose. Tighten the switch to 12 Nm (8.8 lb.ft).
*15. Remove feed hose holder B from the steering gearbox mounting bracket, located on the passenger side (one bolt).*
16. Remove the rear engine mount stop (two nuts), then remove the rear engine mount stop bolt. The stop bolt will not be reused.
17. M/T models only: Remove the two bolts securing the shift cable bracket.
18. Lay the new feed hose next to the original feed hose in the engine compartment. Line up the hoses as closely as possible.
NOTE:
When lining up the feed hoses, do not bend or scratch the painted metal line section of the new hose. Even a scratch on the paint could cause future P/S line corrosion.
19. Raise the vehicle on a lift, and make sure it's securely supported.
20. Remove the engine under cover (two bolts and four clips).
21. Remove exhaust pipe A:
^ Remove the rubber exhaust hanger from the subframe.
^ Remove exhaust pipe A along with the three way catalytic converter (TWC) (nine self-locking nuts). The nuts will not be reused.
^ Support exhaust pipe B with a stand.
2007-08 TL is shown. Earlier models are similar.
22. Remove the exhaust heat shield.
*23. Remove the feed line holder from the front suspension subframe, located on the driver's side (one bolt). Remove the holder from both the feed and return lines, and discard (it will not be reused).*
24. Remove the vacuum line bracket from the rear engine mount (one bolt).
25. Remove the heat shield bolt from the front of the rear engine mount. The bolt is next to the secondary 02 sensor (bank 1, sensor 2).
