Hose and Coolant Flush TSB for smell issue!!!

Please help:
Anyone have access to the full TSB?
I received my car back today from the dealership after they performed the TSB for the smell issue when the heat is on. Well the smell is still there and maybe a little worse, however I'm giving is some time in case its just a residual smell.

After getting it home I opened the hood and noticed metal filings all over the cross member, fuse box etc (see photos)
I was wondering if the TSB specifies any drilling? Looks to me like the tech must have stripped one of the bolts on the thermostat housing and drilled it out to install a nut and bolt!!!

Oh man that sucks! I had/have a feeling the hoses were not the issue; I mentioned that in the other post. I still believe you have a heater core problem.
As for the shavings, I'd march my as back to the dealer and ask them about it, they should have at the very least mentioned it. There is no drilling involved in the hose TSB.

#PIP4988A: Objectionable Underhood Odor From The Coolant - Flush Cooling System And Replace Rubber Hoses - (Feb 7, 2013)
Subject: Objectionable Underhood Odor From The Coolant - Flush Cooling System And Replace Rubber Hoses
Models: 2012-2013 Chevrolet CamaroBuilt Prior to June 15, 2012This PI was superseded to update parts information. Please discard PIP4988.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern Some customers may comment on an objectionable underhood odor that is coming from the engine coolant.
The odor is a by-product in the rubber curing process that continues after the vehicle is produced.
The odor is temporary; noticed early in the life of the vehicle; often in warmer climates and is usually gone completely in the first couple of months after production.
Recommendation/InstructionsIf the condition persists, the system should be flushed and the coolant hoses replaced with the updated part numbers listed below.


If this concern is encountered, follow the procedure below to clean the cooling system:
  1. Completely drain the cooling system by following the SI Cooling System Draining and Filling procedure. If equipped with a block heater, remove it as well. If equipped, also remove the engine block plug shown below. This image has been resized. Click this bar to view the full image. The original image is sized 1239x1183 and weights 24KB.
  2. Remove the thermostat and reassemble without the thermostat in place. Refer to SI procedures for the removal procedure.
  3. Fill the cooling system by following the SI Cooling System Draining and Filling procedure but instead of filling with a 50/50 mix of coolant and water, fill the cooling system with drinkable water and one bottle of GM Heavy Duty Cooling System Cleaner. Avoid spilling the solution on the vehicle's finish. This cleaner is in liquid form and contains a neutralizer. Do not substitute other cleaners.
  4. Drive the vehicle for 40-60 minutes with the heat on high.
  5. Stop the engine and allow it to cool.
  6. Drain the cooling system by following the SI Cooling System Draining and Filling procedure. Also, drain the engine block by removing the engine block plug. If equipped with a block heater, remove it as well.
  7. Fill the cooling system by following the SI Cooling System Draining and Filling procedure but instead of filling with a 50/50 mix of coolant and water, fill the cooling system with clean, drinkable water.
  8. Run the engine for 10 minutes to circulate the water.
  9. Stop the engine and allow it to cool.
  10. Repeat steps 6 through 9.
  11. Drain the cooling system by following the SI Cooling System Draining and Filling procedure. Also, drain the engine block by removing the engine block plug. If equipped with a block heater, remove it as well.
  12. Remove the surge tank. Thoroughly clean it with hot water and install it again.
  13. Fill the cooling system by following the SI Cooling System Draining and Filling procedure but instead of filling with a 50/50 mix of coolant and water, fill the cooling system with plain drinkable water.
  14. Run the engine for 10 minutes to circulate the water.
  15. Stop the engine and allow it to cool.
  16. Drain the cooling system by following the SI Cooling System Draining and Filling procedure. Also, drain the engine block by removing the engine block plug. If equipped with a block heater, remove it as well.
  17. Replace all rubber cooling system hoses following SI procedures.
  18. Install the thermostat using a new water pump inlet seal. Refer to SI procedures for the installation procedure. Important: Only use Premixed DEX–COOL® or a 50/50 mix of DEX–COOL and clean, drinkable water when refilling the cooling system.
  19. Fill the cooling system by following the SI Cooling System Draining and Filling procedure.
  20. Test drive the vehicle, allow to cool and double check the coolant level to complete the repair.

nyrfan Thanks for the feedback.
If you look at the picture of the thermostat housing you'll see the nut and bolt. I believe they must have had a problem with the bolt into the water pump housing. What really gets me is that they could have blown away the metal shavings and I have not been any wiser.

It looks like the original bolt was replaced with a nut and bolt. The threads in the water pump housing probably stripped out and they drilled through to put the longer bolt in with the nut.
