In Progress. This will be all the information that I put in about Why, tools required, parts/fluids required, etc.
Main information page with why this DIY is needed, some important notes, previous steps required, parts required, and tools required.
Why: These steps are required prior to doing anything other than basic maintenance because there is no room to reach most things otherwise.
- This DIY was done with pictures from four different cars (B6 S4, B7 S4, and two B7 RS4s) so I will try to label the pictures whenever I feel that it is appropriate.
- Also this DIY is broken down into three different sections for a reason. For example, certain repairs require just removing the front bumper as other repairs require removing the front bumper and loosening the core support into service position. Few repairs and/or modifications require fully removing the core support but it is important to put this in because of repairs like replacing the AC compressor.
Previous steps required:
- If you plan on fully removing the core support then you need to have the AC system refrigerant evacuated with the proper equipment by someone that is qualified/certified to work with automotive AC systems PRIOR TO doing any other steps. The AC refrigerant is harmful to the environment and it can hurt you if you just loosen a line and release it that way.
For example, I purchased an AC machine for this because I finally have been doing enough work to require it. My machine looks like this:
It hooks up to the AC service ports in the below picture.
- Jacking up the front end and supporting the front of the car on jack stands.
- Removing the belly pan, if there is one. http://audirevolution.net/forum/index.php?topic=2922.0
- Remove the front headlights - This is B6 specific - http://audirevolution.net/forum/index.php?topic=2972.0
- Drain the coolant. This step is required only if you are going to fully remove the core support. http://audirevolution.net/forum/index.php?topic=2941.0
- Washer solvent/fluid - This is required anytime that you remove the front bumper because it is very common to leak a bunch all over the place.
- Coolant - If drained to fully remove the core support.
- Power Steering fluid - If the core support is fully removed.
- Engine oil - RS4 specific - If the core support is fully removed.
Will update later
