Buy Ford Edge Serpentine Belt Drive Component Kits

A serpentine belt drive component kit (also called a drive belt kit, accessory belt kit, or multi-rib belt kit-and sometimes just "fan belt" kit) bundles the parts that spin the Edge's front-of-engine accessories. These parts move the alternator, air-conditioning compressor, and other add-ons so your battery charges, your A/C blows cold, and everything runs quietly.

Most kits include:

• A new serpentine/drive belt (multi-rib).
• An automatic belt tensioner.
• One or more idler pulleys.
• Mounting hardware (as needed).
  Buying these together helps you fix the whole system at once, not just the belt. Many makers recommend replacing the tensioner and idlers when you replace the belt to prevent noise and early wear. See Dayco's note on system replacement for why this matters. (Dayco tech tip PDF.)

The belt loops around ribbed pulleys and is kept tight by the spring-loaded tensioner. Proper tension prevents slip and noise. Idler pulleys guide the belt so it tracks straight. If any part is worn-belt, tensioner, or pulley-the whole system can squeal, chirp, or fail.

Ford Edge models span many years and engines. Belt routing, pulley count, and even the type of A/C belt can change by engine and model year. Always match parts to your exact VIN and engine code and confirm the belt routing in your owner's manual. You can pull up the maintenance and manual pages on Ford's site: Ford maintenance schedule and the Edge owner's manuals. (Ford Motor Company, Ford Service Content)

Some newer engines use a separate "stretch-fit" belt for the A/C that has no tensioner. It's installed with a special tool and is not reused once removed. If your Edge uses a stretch A/C belt, follow the service steps and use the right installer tool. (Gates Stretch Fit™ tools.)

Modern EPDM belts don't show cracks the way old belts did. Instead, they slowly lose rib material-like tire tread wearing down. Gates advises checking belt condition around 60,000 miles; EPDM belts can often run near 100,000 miles, but wear must be measured, not guessed. (Gates belt inspection tip.) Many consumer guides suggest planning replacement somewhere in the 60,000-100,000-mile range, depending on inspection results and use. (AAA overview.) Dayco also recommends inspecting the belt drive around 60,000 miles. (Dayco serpentine inspection guide.) (Gates, AAA, Dayco)

• Squeal, chirp, or grind from the belt area.
• Battery light on or dim lights (alternator under-driven).
• A/C not cooling well at idle.
• Visible belt glazing or ribs that look "rounded" or "U-shaped" instead of sharp "V" valleys (a sign of EPDM wear). (.)

Replacing just the belt can leave a weak tensioner or idler that ruins the new belt. System replacement (belt + tensioner + idlers) helps restore correct tension and alignment so the new belt lasts and the noise stays away. (Dayco tensioner guidance.)

1. Study the belt routing diagram (under-hood label or your Edge owner's manual).
2. Use a serpentine belt tool or long ratchet to rotate the tensioner and remove the old belt.
3. Spin idlers and accessories by hand and feel for roughness.
4. Replace the tensioner and idlers if noisy, loose, or seized.
5. Route the new belt, leaving the easiest pulley for last.
6. Pull the tensioner, slip the belt on, and verify every rib is seated in every groove.
7. For stretch-fit A/C belts (if equipped), follow the specific tool procedure; these belts don't reuse. (Gates tool page.)

• Serpentine belt tool or long 3/8-in. or 1/2-in. drive ratchet.
• Socket set for tensioner/idler bolts.
• Torque wrench (follow the service manual specs).
• Flashlight and mirror to check belt seating.
• Stretch-belt installer (if your A/C uses a stretch belt).

Start the engine and watch the belt. It should run true with no side-to-side walk and no fluttering tensioner arm. Listen for chirps or squeals. Turn the A/C on and off to confirm quiet operation. If the belt rides off a rib, shut down and reseat it.

If the belt has been soaked with oil or coolant, replace it-fluids damage EPDM. Also, don't use belt dressing on serpentine belts; it can make noise worse and speeds wear. Instead, fix root causes like alignment, worn pulleys, or a weak tensioner. (Dayco: how to fix belt noise.)

For reliable, quiet operation, treat the Edge's accessory drive as a system. Inspect around 60,000 miles, replace worn parts together (belt, tensioner, idlers), avoid belt dressings, and follow the routing and procedures in your owner's manual. Use the linked Ford resources and the technical guides from belt manufacturers to keep your serpentine/drive belt system in top shape.
