Power Steering Hose Fracture

1. 1Fault

   • Leak
   • Smoke or fire
   • Under extreme steering maneuvers, such as turning the steering wheel fully left or right while braking, the hose may fracture and leak fluid; power steering assist would be lost and steering effort would increase.
   • On vehicles with hydro-boost power brakes it could also result in loss of power brake assist and increased braking effort; if the fluid sprays onto hot engine parts, an engine compartment fire could occur.
   • With the Hydroboost braking system, braking assist will be limited to the reserve power assist system; the braking systems on vehicles without Hydroboost are unaffected.
   ↓→

2. 2Finding the cause

   • Power Steering Line: broken

   Possible causes

   • The high pressure power-steering hose was manufactured with an incorrect compound, making it susceptible to high pressure failure at the elevated fluid temperatures and pressures that can occur during simultaneous braking and steering inputs.

   Steps to confirm (in the document’s order)

   1. Inspect and record the date code on the power steering pressure line; it is printed on the hose and repeated approximately every 6 inches (150 mm).
   2. Vehicles with the hydro-boost system have two hoses to inspect, others only one; the conduit may have to be removed to read the date code.
   3. The suspect date codes are 07135F-2 and 07145F-2; if the hose carries one of them, it must be replaced.
   ↓→

3. 3Correction

   • Power Steering Line: replaced

   Repair

   1. If the date code is not one of the listed codes, replace the conduit if applicable; no further action is required.
   2. For Silverado/Tahoe/Sierra/Yukon/Escalade, hose replacement follows SI documents 756552 (Non Hydro-Boost Pressure line), 651043 (Power Steering Pump to Hydro-Boost Pressure line) and 651019 (Hydro-Boost to Steering Gear Pressure Line).

   Parts

   • Less than 10% of the involved vehicles will require hose replacement; if parts are required, the appropriate hose(s) are ordered from GMSPO.

   Caution

   • This bulletin is a revision to address hoses used to service 1991-2006 vehicles; dealers who ordered these hoses for service are identified in the attachment to the administrative message.
   • Vehicle eligibility should be confirmed through GMVIS before beginning recall repairs; not all vehicles within the breakpoints may be involved.

   1. Inspect the oil pan and engine covers for leakage due to over-tightened, damaged or out of place gaskets.
   2. Verify that the dipstick tube is fully seated in the block.
   3. Let the vehicle sit for at least 15 minutes after the engine has been shut off before reading the oil level.
   4. Verify that the positive crankcase ventilation (PCV) system is operating properly; blockages, restrictions or damage to it can increase oil use.
   5. Do not test oil economy until the vehicle has accumulated at least 6400 km (4000 mi).

   Repair

   • If the final evaluation shows the engine uses more than 0.946 liter (1 qt) in 3200 km (2000 mi), follow the published symptom diagnostics in the appropriate Service Manual.

   Caution

   • The accepted rate of oil consumption for these engines is 0.946 liter (1 qt) in 3200 km (2000 mi).
   • This rate does not apply to vehicles driven aggressively, at high RPM, at high speeds, or (for trucks) loaded; oil consumption under these conditions will be more.

   ↓→

3. 3Correction

   • Intake Valve: cleaned

   Repair

   1. If there is no valve damage and no cam follower out of place, perform the cleaning procedure to free sticking valves and remove carbon from the valves and pistons.
   2. If valves are damaged or cam followers are out of place, make the engine mechanical repairs first and then perform the cleaning procedure to prevent a return.
   3. Fill Cleaner Kit J-35800-A with about 650 ml (22 oz, 2 cans) of Air Intake, Combustion Chamber Cleaner and set the air pressure at the tool to 260 kPa (40 psi).
   4. With GDS 2 or a scan tool, command engine idle to 2000 rpm so the engine does not stall.
   5. With the engine at operating temperature in a well-ventilated area, slowly and carefully induce the cleaner into the engine, taking about 3 minutes.

Water or Ethylene Glycol in Transmission Fluid

1. 1Fault

   • Vibration or shudder
   • Water or ethylene glycol in ATF changes the friction of the clutches, frequently causing shudder during engagement or gear changes, especially during torque converter clutch engagement.
   ↓→

2. 2Finding the cause

   Steps to confirm (in the document’s order)

   1. An indication of water in the ATF: ATF blowing out of the transmission vent tube.
   2. The ATF may appear cloudy or, with extreme contamination, look like a strawberry milkshake.
   3. There may be visible water in the oil pan or a milky white substance inside the pan area.
   4. Spacer plate gaskets appear swollen or wrinkled in areas where they are not compressed.
   5. If water is found in the ATF and its source is not identified, or a leaking in-radiator transmission oil cooler is suspected, a simple and quick test kit that detects ethylene glycol in ATF is available.

Tire Radial Force Variation (RFV) Service Bulletin

1. 1Fault

   • Vibration or shudder
   • The most common ride concern involving tire radial force variation is shake on smooth roads at highway speed, 105-115 km/h (65-70 mph).
   ↓→

2. 2Finding the cause

   Possible causes

   • Tire related smooth road highway speed shake can be caused by three conditions: imbalance, out of round and tire force variation.

   Steps to confirm (in the document’s order)

   1. With the vehicle raised, center the wheels on the hub by loosening all wheel nuts and hand-tightening them while shaking the wheel, then torque to specification with a torque wrench, not a torque stick.
   2. If light brake application increases the pulsation felt in the steering wheel, go to the brake-induced pulsation diagnosis in the Brakes section of the service manual.
   3. A reading of 35 to 50 Hz typically indicates a first order propshaft vibration.
   4. Generally a reading between 10 and 20 Hz indicates a tire/wheel vibration.
   5. If vibration continues after 10 minutes of driving above 72 km/h (45 mph), temporary tire flat-spotting can be ruled out.

   2 more points
   ↓→

3. 3Correction

   Repair

   • If the radial runout of a tire/wheel assembly is more than 0.040 in (1.02 mm), match mount the tire to the wheel to get below 0.040 in (1.02 mm).

   Caution

   • On the balancer always center the wheel by the pilot bore; never use the hub-cap bore, since it is not a precision machined surface.
