So Fix it

Bleeding the Clutch on 2003 F 150

Ford equipped the 2003 F-150 trucks that have the optional standard transmission package with a hydraulic clutch system. The clutch system consists of a master cylinder, slave cylinder and a hydraulic clutch line. Depressing the clutch pedal actuates the clutch master cylinder, which pressurizes the hydraulic line and slave cylinder, similar to how a hydraulic brake system works. Air bubbles suspended in the hydraulic fluid will lead to a spongy feel at the clutch pedal and could cause clutch drag and gear grind as the transmission is put into gear. Bleed air from the clutch with the engine cold.

Instructions

1

Place the vehicle in neutral and set the parking brake.

2

Open the hood and locate the clutch master cylinder on the right side of the engine compartment against the firewall. Wipe dirt or debris from the clutch master cylinder reservoir cap, using a clean shop rag

3

Remove the reservoir cap and diaphragm. Fill the clutch master cylinder reservoir up to the Full mark with brake fluid.

4

Depress and release the clutch pedal through the full range of travel several times.

5

Locate the bleeder screw on the drivers side of the transmission, just above where the clutch hydraulic line enters the transmission. Remove the rubber bleeder screw cover.

6

Attach a 1/4-inch inside diameter clear vinyl hose to the bleeder screw. Pour a small amount of new brake fluid into a clear container. Submerge the free end of the hose in the brake fluid to prevent drawing air back into the system.

7

Have a helper fully depress and release the clutch pedal five times, then hold the clutch pedal down.

8

Loosen the bleeder screw, using a wrench, and observe the fluid escaping through the hose. Tighten the bleeder screw once fluid flow has stopped.

9

Repeat steps 7 and 8 as necessary until no air is visible in the escaping fluid stream. Occasionally check and top off the fluid level in the reservoir to prevent introducing air into the system. Do not allow the reservoir to run dry.

10

Tighten the bleeder screw securely, using a wrench. Remove the clear vinyl hose. Install the rubber bleeder screw cover.

11

Have your helper slowly pump the clutch pedal through the full range of travel several times and check the bleeder screw for leaks.

12

Depress the clutch pedal halfway and release it twice, then depress and release the clutch pedal through the full range of travel three times.

13

Check and top off the fluid level in the reservoir with brake fluid. Install the reservoir diaphragm and cap.

14

Start the vehicle and check for proper operation of the clutch before operating the F-150 in traffic.
