Drain and replace power steering fluid in the 1972 Ford F-100 302 V8 power steering system to maintain proper operation and prevent component wear.
Warnings
⚠Power steering fluid is petroleum-based and can damage paint. Clean any spills immediately with soap and water.
⚠Do not turn the steering wheel with the reservoir empty or pump running dry, as this will damage the power steering pump.
ℹ️This procedure uses Type F ATF, which was the original Ford specification. Do not substitute with modern ATF+4 or multi-vehicle fluids without verifying compatibility.

Fluids
- Type F ATF — 2 qt
Preparation
- Park vehicle on level ground and set parking brake.
- Allow engine to cool to ambient temperature if recently driven.
- Raise front of vehicle with jack and support securely on jack stands to allow clearance for steering wheel rotation and access underneath.
- Place drain pan under power steering pump and hoses to catch spilled fluid.
- Have approximately 3-4 quarts of fresh Type F ATF available (2 quarts for fill, extra for flushing).
Procedure
- 1Remove power steering reservoir capLocate the power steering pump with integral reservoir on the driver side of the engine bay. Remove the reservoir cap (which typically incorporates a fluid level dipstick) by twisting or prying it off per the cap type. Wipe the dipstick clean and set aside on a clean shop rag.
- 2Extract old fluid from reservoirUsing a turkey baster or fluid transfer pump, remove as much old fluid as possible from the power steering reservoir. Transfer the old fluid to your drain pan. Continue extracting until the reservoir is as empty as possible through the filler neck.
- 3Disconnect return hoseLocate the low-pressure return hose connection at the power steering pump reservoir. This is typically the lower hose secured with a hose clamp. Loosen the hose clamp using the appropriate tool for the clamp type (flathead screwdriver for worm-gear clamps, or hose-clamp pliers for spring clamps), then carefully twist and pull the return hose off the reservoir nipple. Allow remaining fluid to drain into the pan. Position the hose end into the drain pan.
- 4Flush the systemFill the power steering reservoir with fresh Type F ATF to the FULL COLD mark. Have an assistant slowly turn the steering wheel full lock to lock (all the way left, then all the way right) 4-5 times while you observe old fluid draining from the disconnected return hose. Do NOT start the engine. Add more fresh fluid as the reservoir level drops. Continue until fluid draining from the return hose runs clear and red, not dark or contaminated.
- 5Reconnect return hoseOnce fluid runs clear, push the return hose firmly back onto the reservoir return nipple until fully seated. Slide the hose clamp back into position over the hose connection and tighten securely with a flathead screwdriver. Ensure the clamp is positioned over the hose bead on the nipple.
- 6Fill reservoir to proper levelAdd fresh Type F ATF to the reservoir until the level reaches the FULL COLD mark on the dipstick or reservoir. Do not overfill. Install the dipstick/cap loosely.
- 7Bleed air from systemWith the engine still off and transmission in Park, turn the steering wheel slowly from lock to lock 10-15 times to purge air from the system. Check fluid level after every 5 turns and top off as needed. The level will drop as fluid fills the system and air is displaced.
- 8Start engine and complete bleedingStart the engine and allow it to idle. Turn the steering wheel slowly from lock to lock 3-4 times. Check for leaks at the return hose connection and around the pump. Check the fluid level with the engine running (fluid will appear slightly higher when warm). Top off to the FULL HOT mark if needed. Listen for any whining or groaning noises that indicate air in the system.
- 9Final fluid level checkAllow the engine to run for 2-3 minutes, then turn the steering wheel lock to lock one final time. Shut off the engine. Remove the dipstick and verify fluid level is between FULL COLD and FULL HOT marks. Top off if needed. Securely install the dipstick/cap.
Reassembly
- Lower vehicle from jack stands.
- Dispose of used power steering fluid properly at a recycling center or automotive shop that accepts used petroleum products.
- Wipe down any spilled fluid from engine bay components and undercarriage.
Verification
- Start engine and verify no leaks at return hose connection or pump.
- Turn steering wheel full lock to lock with engine running and verify smooth operation with no whining, groaning, or binding.
- Check fluid level with engine at operating temperature and top off if needed to FULL HOT mark.
- Test drive vehicle and verify power steering assist is operating normally with no noise or stiffness.
- Recheck fluid level after test drive and inspect for leaks.
