This procedure covers the removal, cleaning, and replacement of battery terminals on a 2011-2014 Ford F-150 with 5.0L V8 Coyote engine, including proper torque specifications for terminal and ground connections.

Warnings

Tools required

Parts

• Battery terminals (positive and negative) × 2 — Use OEM specification or quality aftermarket
• Battery terminal grease or anti-corrosion spray × 1 — Dielectric grease or battery terminal protectant

Preparation

1. Park vehicle on level surface and turn off ignition
2. Ensure all electrical accessories are off
3. Open hood and locate battery in right side of engine compartment
4. Note radio presets and record any trouble codes if desired
5. Inspect battery and terminals for damage or excessive corrosion

Procedure

1. 1

   Disconnect negative battery terminal
   Using a 8mm wrench or socket, loosen the bolt on the negative (-) battery terminal (black cable). Remove the terminal from the battery post and position the cable away from the battery to prevent accidental contact.

   Battery Terminal Bolts6 Nm (4 lb-ft)
2. 2

   Disconnect positive battery terminal
   Using a 8mm wrench or socket, loosen the bolt on the positive (+) battery terminal (red cable). Remove the terminal from the battery post. Be careful not to let the terminal contact any metal surfaces.

   Battery Terminal Bolts6 Nm (4 lb-ft)
3. 3

   Remove ground cable connections if replacing terminals
   If replacing the negative terminal assembly, locate the ground cable connection points at the engine block and body. Use a 13mm socket to remove the ground cable bolts. Note the exact routing and connection points for reinstallation.

   Ground Cable Bolt17 Nm (13 lb-ft)

   Ground Strap Bolts12 Nm (9 lb-ft)
4. 4

   Inspect and clean battery posts
   Inspect battery posts for damage or excessive corrosion. Clean the battery posts using a wire brush or battery post cleaner tool, removing all corrosion and buildup. For heavy corrosion, apply baking soda and water solution, then rinse and dry thoroughly.
   ⚠Neutralize any battery acid with baking soda solution before cleaning to prevent skin contact
5. 5

   Remove old terminals and prepare cables
   Cut away old terminals from the cables if they are corroded or damaged. Strip cable ends to expose clean copper wire (approximately 1/2 inch). If terminals are reusable, clean the interior contact surfaces thoroughly with a wire brush.
   ℹ️Ensure cable strands are not frayed or damaged; replace entire cable if wire is compromised
6. 6

   Install new terminals on cables
   Insert the cleaned cable ends into the new terminals. Ensure the cable is fully seated in the terminal. Tighten the terminal bolt to secure the cable, ensuring a solid mechanical and electrical connection.

7. 7

   Reinstall ground cable connections
   Reconnect the ground cable to the engine block and body ground points in the exact locations noted during removal. Ensure contact surfaces are clean and free of paint or corrosion. Tighten ground cable bolt and ground strap bolts to specification.
   ⚠Proper ground connections are critical for vehicle electrical system operation

8. 8

   Connect positive battery terminal
   Place the positive (+) terminal (red cable) onto the positive battery post. Ensure the terminal is seated completely onto the post. Tighten the terminal bolt to specification. Do not overtighten as this can damage the terminal or battery post.

   Battery Terminal Bolts6 Nm (4 lb-ft)
9. 9

   Connect negative battery terminal
   Place the negative (-) terminal (black cable) onto the negative battery post. Ensure the terminal is seated completely onto the post. Tighten the terminal bolt to specification. Do not overtighten.
   ℹ️Small spark when connecting negative terminal is normal due to system capacitance

10. 10

    Apply terminal protection
    Apply a thin coat of dielectric grease or battery terminal protection spray to the terminals and battery posts to prevent future corrosion. Wipe away any excess.
    ℹ️Do not use excessive grease as this can attract dirt and debris

Reassembly

1. Verify all terminal connections are tight and secure
2. Ensure no tools or debris remain in engine compartment
3. Check that ground cables are properly routed and secured

Verification

• Turn ignition to ON position and verify dashboard lights illuminate properly
• Start engine and verify normal operation
• Check for proper charging system operation (battery voltage should be 13.5-14.5V with engine running)
• Test electrical accessories (lights, radio, windows) for proper function
• Reset clock and radio presets as needed
• Inspect terminals after first drive for any signs of looseness or heating
