The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
A technician may comment of coolant loss in the water pump area, usually at PDI. The leak may be more prevalent with cold ambient temperatures.
Recommendation/Instructions:
Confirm coolant leak at water pump to block interface.
Run vehicle to operating temperature and let cool; repeat this procedure 2 times. Inspect area for leakage.
• a. If the suspected leak has stopped no further action is needed. Return vehicle to service.
• b. If the concern is still present continue to step #3.
Caution: HOT COOLANT COULD SPRAY IF CAP IS FULLY REMOVED.
Carefully Loosen coolant cap to relieve pressure, tighten cap after pressure relief.
Loosen the four bolts (two on front of engine, two on rear of pump) on the water pump (approx 360°) but do not fully remove.
Torque the bolts to 25nm +/- 4nm (18.5 FT/LB +/- 3 ft. lbs) in the following sequence.
• 1. Top bolt on front of engine.
• 2. Lower bolt on rear of water pump.
• 3. Lower bolt on front of engine.
• 4. Upper bolt on rear of water pump.
Note: A crows foot may be used (where required) to ensure the torque value is met.
Top coolant in surge tank to cold full mark.
Clean and ensure all residual evidence of leaks is removed from top and lower section of water pump.
Pressure check and run vehicle to operating temperature to check for coolant leak at water pump to block joint. Let vehicle cool and heat cycle 2 additional times.
• a. If the suspected leak has stopped no further action is needed. Return vehicle to service.
• b. If a leak is still present from the o-ring area after the re-torque of the water pump, the water pump o-ring will need to be replaced. Make sure to follow the sequential torque procedure listed above when replacing the o-ring.

#09-08-50-007: Toe Kick Panel of Front Seat Cushion Cover Loose or Hanging Unsecured (Reattach with Tie Straps) - (Mar 24, 2009)
Subject: Toe Kick Panel of Front Seat Cushion Cover Loose or Hanging Unsecured (Reattach with Tie Straps)
Models: 2006-2009 Chevrolet HHR
--------------------------------------------------------------------------------
Condition
Some customers may comment that the toe kick panel of the driver or passenger front seat cushion cover is loose or hanging unsecured.
Cause
This condition may be caused by the J-channel clips, which retain the toe kick panel to the seat cushion frame, releasing from the frame. The retention strength of the clip may not be sufficient enough to keep it securely retained.
Correction
Important: The toe kick panel of the front seat cushion cover may be one of two designs. Visually verify which design the seat cover has. If the toe kick panel is the "strap and hook" design (shown above), and exhibits damage, the seat cushion cover would have to be replaced. The following repair is specific to toe kick panels with the J-channel design.
Important: If the above condition is noted on a front seat cushion cover with J-channels, repair following the steps below. DO NOT replace the front seat cushion cover.
Drill holes through the toe kick panel J-channels (one each side) and re-secure the panel with tie straps using the following steps:
Slide the seat fully forward.
Disengage the toe kick cover panel from the seat cushion frame, and flip the panel over to expose the J-channels (1).
Drill a 6.35 mm (1/4 in) diameter hole through the J-channel and fabric on each side. Ensure that the hole is centered in the J-channel as shown above.
Tip
Once installed and trimmed, the tie strap length is much shorter than the starting 355 mm (14 in) length. A shorter tie strap can be used, however the longer tie strap may be easier to get in position while working under the seat.
Insert a tie strap, obtained locally, into each hole in the toe kick panel. Approximate size of the tie strap should be 4.75 mm (0.187 in) width and 355 mm (14 in) length.
Reposition the toe kick panel and secure the two tie straps to the underside of the seat cushion.
Important: The seat cushion above has been removed for illustration purposes.
5.1. Slide each tie strap under the suspension wire of the seat cushion as shown above. Tighten the tie straps, ensuring that the toe kick panel fabric is straight and taut.
5.2. Clip off the excess strap with wire snips.

#PIP4611: Misfire Smoking And/Or No Heat With Loss Of Coolant - (Mar 25, 2009)
Subject: Misfire, Smoking and/or No Heat With Loss of Coolant
Models: 2009 Chevrolet Malibu and HHR
2009 Pontiac G6 and Solstice
2009 Saturn Aura and Sky
Equipped With 4 Cylinder Ecotec Engine RPO's LE5 and LE9
--------------------------------------------------------------------------------
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
On rare occasions, a low coolant light may be experienced due to a low coolant level. However, no visible leaks will be present upon inspection. A brief engine misfire and DTC P0300 or P0304 may also be experienced immediately after the engine is started. If the coolant level is low enough, a loss of heat from the HVAC may be experienced and DTCs P0117 or P0128 may be stored.
Recommendation/Instructions:
If this concern is experienced with no sign of an external leak, perform each step of the SI diagnostics for "Loss of Coolant" and repair as necessary. If there is no problem found after following the diagnostics, pressurize the cooling system again and allow the engine to hot soak for up to 2 hours. If the pressure decays, remove the #4 spark plug and use a bore scope to inspect the top of the piston for any sign of coolant. If a bore scope is not available, place the piston at bottom dead center and inspect the visible area of the piston top through the spark plug hole using a pen light. If there is any sign of coolant on the top of the piston, remove the cylinder head and inspect the face for damage in the area around the #4 cylinder fire ring. If damage is found replace the cylinder head. See illustration callout #1 below for location/example of damage.

#09-06-01-004: Clicking/Ticking Sound/Noise Heard from Rear of Engine (Install Sound Isolation Cover Over High Pressure Fuel Pump) - (Apr 1, 2009)
Subject: Clicking/Ticking Sound/Noise Heard From Rear of Engine (Install Sound Isolation Cover Over High Pressure Fuel Pump)
Models: 2008-2009 Chevrolet Cobalt, Cobalt SS, HHR, HHR SS
2007-2009 Pontiac Solstice GXP
2007-2009 Saturn SKY Redline
2007-2009 Opel GT
2007-2009 Daewoo G2X
Equipped with 2.0L Engine (VIN X -- RPO LNF)
--------------------------------------------------------------------------------
Condition
Some customers may comment on a ticking sound from the rear of the engine. Upon investigation, the technician may find the sound coming from the high pressure fuel pump and/or the injectors.
Cause
The 2.0L turbo engine (VIN X - RPO LNF) uses a direct injection fuel system that operates at very high fuel pressures. A direct injection fuel system produces a rapid, clicking/ticking sound that can be heard from the engine compartment. The sound is more evident when outside around the vehicle or when the hood is open. The sound is more noticeable during idle, and is more frequent during a cold start but lessens once the engine is warm. The rapid ticking noise on cold start up is the fuel pump (located on the rear of the cylinder head) building up high fuel pressure. When the engine warm-up is completed, the high pressure fuel pump will continue to tick at a lower rate of approximately one tick per second during idle. The clicking sound is the fuel injectors pulsing on and off under higher fuel pressures. These sounds are the results of a normal direct injection fuel system operating properly.
Correction
Install a sound isolation cover over the high pressure fuel pump following the procedure below. This will make the sound coming from the high pressure fuel pump less noticeable, but it will not completely eliminate it.
Important: DO NOT attempt to replace any parts for this kind of clicking or ticking concern.
Verify the noise is coming from the high pressure fuel pump.
Remove the air inlet grille panel. Refer to Air Inlet Grille Panel Replacement in SI.

Equipped with 2.0L Engine (VIN X -- RPO LNF)
--------------------------------------------------------------------------------
Condition
Some customers may comment on a ticking sound from the rear of the engine. Upon investigation, the technician may find the sound coming from the high pressure fuel pump and/or the injectors.
Cause
The 2.0L turbo engine (VIN X - RPO LNF) uses a direct injection fuel system that operates at very high fuel pressures. A direct injection fuel system produces a rapid, clicking/ticking sound that can be heard from the engine compartment. The sound is more evident when outside around the vehicle or when the hood is open. The sound is more noticeable during idle, and is more frequent during a cold start but lessens once the engine is warm. The rapid ticking noise on cold start up is the fuel pump (located on the rear of the cylinder head) building up high fuel pressure. When the engine warm-up is completed, the high pressure fuel pump will continue to tick at a lower rate of approximately one tick per second during idle. The clicking sound is the fuel injectors pulsing on and off under higher fuel pressures. These sounds are the results of a normal direct injection fuel system operating properly.
Correction
Install a sound isolation cover over the high pressure fuel pump following the procedure below. This will make the sound coming from the high pressure fuel pump less noticeable, but it will not completely eliminate it.
Important: DO NOT attempt to replace any parts for this kind of clicking or ticking concern.
Verify the noise is coming from the high pressure fuel pump.
Remove the air inlet grille panel. Refer to Air Inlet Grille Panel Replacement in SI.
Disconnect the engine wiring harness electrical connector from the high pressure fuel pump.
Remove the engine wiring harness from the high pressure fuel pump cover bracket.
Remove the high pressure fuel pump cover bolts (1).
Remove the high pressure fuel pump cover bracket.
Remove the old design cover and install the new high pressure fuel pump insulator, GM P/N 12628069.
Position the high pressure fuel pump cover bracket. Install the high pressure fuel pump cover bolts.
Tighten
Tighten the bolts to 10 N·m (89 lb in).
Connect the engine wiring harness electrical connector to the high pressure fuel pump.
Attach the engine wiring harness to the fuel pump cover bracket using a zip tie.
Install the air inlet grille panel. Refer to Air Inlet Grille Panel Replacement in SI.

This bulletin is being revised to add the 2006 model year for Cobalt, Pursuit, G6, and HHR. Please discard Corporate Bulletin Number 07-07-30-005B (Section 07-Transmission/Transaxle).
--------------------------------------------------------------------------------
Condition
Some customers may comment on the illumination of the Malfunction Indicator Lamp (MIL) or the Service Engine Soon (SES) light, the power door locks, cruise control, shift interlock, retractable hardtop being inoperative and engine speed revs limited to 4,000 RPM in first gear after a cold start or cold soak with temperatures between 0° to 10°C (32°F to 50°F).
Customers with hybrid vehicles may also comment on the following conditions:
-- Hybrid Autostop, regen or boost inoperative
Cause
These conditions may be caused by the TCM setting a false DTC P1818 (Transmission Fluid Pressure (TFP) Valve Position Switch Indicates Drive without Drive Ratio).
Correction
Verify the conditions and reprogram the transmission control module (TCM) with the new updated calibration using the procedure below.
Check for DTCs.
Clear DTC P1818.
Start the engine.
Apply the brake pedal.
Place the transmission in reverse.
With a Tech 2®, monitor the transmission fluid pressure (TFP) switch parameter.
• If the TFP parameter indicates Reverse, reprogram the TCM with the updated calibration.
• If the TFP parameter indicates Park/Neutral, refer to DTC P1818 in SI for further diagnosis.
Important: Confirm the newest calibration includes the "false P1818 fix".
An updated TCM calibration is now available to address this concern. This calibration, or any that follow, is designed to address this concern. Reprogram the TCM with the software now available in the TIS2WEB using the Service Programming System (SPS).
If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided. As always, make sure your Tech 2® Diagnostic Scan Tool is updated with the latest software version.
Clear any codes and verify the condition has been fixed.
