Engine/Transmission Mount Drain Hole Procedure
ENGINE/TRANSMISSION MOUNT DRAIN HOLE PROCEDURERequired Tools and Materials
^ Drill
^ 6 mm (1/4 in) drill bit
^ 6 mm (1/4 in) diameter rubber hose
^ 25 mm (1 in) width tape
^ Center Punch
1. Turn the steering wheel to the full left turn position to provide access to the engine and transmission mounts. Raise and support the vehicle.
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
3. Locate the left transmission mount, right front engine mount, and right rear engine mount.
Notice:
The aluminum body of the mount has a 5 mm (13/64 in) thick wall. Drilling more than 8 mm (5/16 in) into the body of the aluminum mount will damage the internal rubber parts of the mount. Damaged mounts must be replaced. Refer to SI for engine and transmission mount replacement procedures if a mount is damaged. To avoid damaging the engine or transmission mount, follow the instructions below.
4. Mount Preparation Instructions
^ Do NOT remove the engine or transmission mounts from the vehicle.
^ Clean loose dirt from the mount before drilling the drain hole.
^ The drain hole must be 25 mm (1 in) above the mount base (1). Apply a piece of 1-inch tape (2) above the mount base. The edge of the tape must touch the mount base. The tape will serve as the centerline height guide (3).
^ Use a center punch (2) to mark the centerline height for the drain hole.
^ Make a drill bit stop (1). The drill bit stop (1) should leave no more than 8 mm (5/16 in) of the drill bit exposed. Use a piece 1/4 in rubber hose or equivalent to make the drill bit stop (1).
^ Use a 6 mm (1/4 in) drill bit to drain the drain hole. Ensure the drill bit stop (1) is on the drill bit before drilling the hole.
^ Do NOT exceed the 8 mm (5/16 in) drain hole depth specification.
Important:
Drill the drain hole as close to the 12 o'clock position as possible. Use the 11-1 o'clock position as a reference for the acceptance area for the drain hole. The front of the vehicle (e.g., engine compartment or front grill) is the 12 o'clock position for the mount.
5. Create a drain hole for the left transmission mount. Refer to the Mount Preparation Instructions before drilling the drain hole.
6. Create a drain hole for the right front engine mount. Refer to the Mount Preparation Instructions before drilling the drain hole.
Important:
Drill the drain hole as close to the 5 o'clock position as possible. Use the 4-7 o'clock position as a reference for the acceptance area for the drain hole. The front of the vehicle (e.g., engine compartment or front grill) is the 12 o'clock position for the mount.
7. Create a drain hole (1) for the right rear engine mount. Refer to the Mount Preparation Instructions before drilling the drain hole.
8. Inspect the flexible pipe section (2) of the exhaust system for proper alignment.
^ A properly aligned flexible pipe will NOT have a noticeable sag in the flexible pipe section (2) of the exhaust system. The flanges (1) will also be level. Refer to the illustration for an example of a properly installed flexible pipe section. If the flexible pipe section (2) of the exhaust system is aligned properly, lower the vehicle. No further action is required.
^ An improperly aligned flexible pipe section (2) will have a noticeable sag in the flexible pipe section (2). The flanges (1) will also NOT be level. Refer to the illustration for an example of an improperly installed flexible pipe section (2). If the flexible pipe section (2) is not aligned properly, proceed to step 2.
9. Loosen the exhaust flexible pipe to muffler nuts (1).
10. Align the flexible pipe section of exhaust system. Use the flanges (1) located on the outboard side of the flexible pipe to determine if the flexible pipe section (2) of the exhaust system is level and aligned properly also, note the position of the flexible pipe section (2). A properly installed flexible pipe section (2) will NOT have a noticeable sag
11. Once the flexible pipe section (2) of the exhaust system is properly aligned, install and tighten the flexible pipe-to-muffler nuts (1).
Tighten
Tighten the flexible pipe-to muffler nuts to 50 Nm (37 lb ft).
12. Lower the vehicle.
