Procedures A and B
Procedure AUse this procedure if there is sufficient clearance to insert the drain hose past the brake pipes. If clearance is restricted, go to Procedure B.
ENDEAVOR FWD
1. Open the engine hood.
2. Raise the vehicle on a hoist. Locate the existing HVAC drain outlet in the dash crossmember (circled).
NOTE:
The drain outlet is offset from the hole opening. It is low in the opening and slightly toward the driver's side of the vehicle (inset photo).
a. Remove the bolt from the power steering hose bracket and gently move the hose toward the driver's side of the vehicle.
b. Unclip the lower two brake lines from the white retaining clip.
WARNING
Take care to not damage the retaining clip or kink the brake pipes when unclipping or reinstalling them. Replace retaining clips if broken.
3. Cut one end of the guide tube at a 45° angle.
4. Apply liquid soap to the short section of the drain hose.
5. Install the drain hose as follows:
a. Slide the drain hose over the guide tube.
b. Insert the guide tube into the drain outlet with the point at the driver's side of the vehicle.
6. Slide the drain hose along the guide tube (short side first) through the hole in the bulkhead until it makes contact with the drain outlet.
7. Once the drain hose is aligned with the drain outlet straighten it and rotate in a clockwise direction while applying light pressure to the hose until it is fully seated.
You may need to rotate it more than once before it is fully seated.
8. Pull on the hose with light pressure to confirm it is properly installed.
9. Remove the guide tube.
10. Re-secure the brake lines in the white clip.
11. Re-secure the power steering hose bracket. Torque the bolt to 12 +/- 2Nm (106 +/- in-lb).

Procedure B
Use this procedure only if there is insufficient brake pipe clearance to insert the drain hose.
1. Remove the HVAC case and evaporator and replace the heater drain grommet (p/n 7801A300). Refer to Group 55 Heating, Air Conditioning & Ventilation in the applicable service manual for removal and installation instructions.
2. Install a cabin air filter (p/n MZ312931) into the blower motor housing (if one is not already installed). Follow the installation instructions included with each filter. Installation instructions are also available on the MDL from the "parts" page by selecting "parts information, then "Technical Resources," then "Accessory Installation Instructions."
NOTE:
Future replacement of cabin air filters (as any other filter) is considered maintenance and is at customer expense.
