2018 Ford Edge 2.0L EcoBoost Timing Chain Replacement Guide (Not a Timing Belt)
Step-by-step instructions with required tools, parts list, TTY bolt notes, and timing verification tips for 2016, 2017, 2018
š§ Edge - Timing Chain Replacement
Your Edgeās 2.0L EcoBoost does not use a timing beltāit uses a timing chain. Replacing the chain is a big job because the front cover has to come off, the engine must be correctly ātimed,ā and several fasteners are torque-to-yield (one-time-use).
Difficulty Level: Advanced | Estimated Time: 10-14 hours
ā ļø Safety & Precautions
- ā ļø Let the engine cool completely before you start (hot coolant/parts burn).
- ā ļø Disconnect the negative battery cable to prevent accidental starts and short circuits.
- ā ļø Support the engine from above before removing the right-side engine mount (the engine can drop/shift).
- ā ļø Many fasteners are torque-to-yield (TTY) (tighten + additional angle). TTY bolts should be replaced, not reused.
- ā ļø If the engine timing is set incorrectly, severe engine damage can occur.

š Before You Begin
- Park on level ground, set the parking brake, and use wheel chocks.
- Disconnect the negative battery cable using a 10mm socket.
- Raise the front of your Edge with a floor jack and support it securely on jack stands.
- Remove the right-front wheel using a 19mm socket and remove the right inner fender liner using a trim clip remover.
- Plan to replace one-time-use bolts (TTY). If unsure, replace them.
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Drain coolant and (optionally) engine oil
- Place a drain pan under the radiator drain.
- Open the drain and remove the coolant reservoir cap to speed draining.
- If youāll be opening the front cover, plan on an oil change afterward (oil can be contaminated). Use a drain pan and the correct socket for the drain plug.
Step 2: Remove the intake ducting and upper engine components
- Remove the air intake duct/airbox as needed using a socket set (8mm-10mm).
- Unplug and unclip harnesses that are routed across the valve cover using a pick set carefully.
- Remove the ignition coil electrical connectors and coils using a 10mm socket.
Step 3: Remove the valve cover
- Remove valve cover fasteners using a socket set.
- Lift the valve cover off. Use a plastic scraper to remove old gasket material without gouging aluminum.
Step 4: Support the engine and remove the right engine mount
- Install the engine support bar (specialty) across the fenders and attach to the engine lift point(s).
- Remove the mount and bracket fasteners using a socket set and breaker bar.
- Reinstallation note: many mount fasteners are TTY. Torque to Ford spec using a torque wrench + torque angle gauge.
Step 5: Remove the serpentine belt
- Rotate the belt tensioner with a serpentine belt tool (specialty) and slip the belt off.
- Take a photo of belt routing before removal. Your phone photo saves headaches.
Step 6: Remove the crankshaft pulley (harmonic balancer)
- Remove the crank pulley bolt using a breaker bar and appropriate socket from your metric socket set.
- Use a harmonic balancer puller kit (specialty) to remove the pulley.
- Important: The crank bolt is typically TTY. Replace it and tighten with a torque wrench + torque angle gauge to Ford spec.
Step 7: Remove the front cover
- Remove the front cover bolts using a socket set.
- Carefully separate the cover. Use a plastic scraperādo not pry aggressively on sealing surfaces.
- Clean mating surfaces using brake cleaner and shop rags.
Step 8: Set the engine to Top Dead Center and lock the timing
- Rotate the engine by hand at the crank using a socket set and 1/2" drive ratchet until timing marks align.
- Install the Ford 2.0L EcoBoost timing tool kit (cam/crank locking tools) (specialty).
- Definition: A locking tool holds the cam/crank in place so timing canāt slip.
Step 9: Remove the timing chain tensioner and guides
- Remove the tensioner fasteners using a socket set.
- Remove the guides using a socket set.
- Keep bolts organized by location. Cardboard ābolt mapā helps.
Step 10: Remove and install the timing chain
- Remove the old chain and compare it to the new one.
- Install the new chain aligning colored links (if present) to the cam/crank timing marks.
- Reinstall guides and tensioner using a socket set.
- Torque to Ford spec using a torque wrench for guides/tensioner fasteners.
Step 11: Verify timing before closing
- Remove locking tools, then rotate the engine by hand two full revolutions using a socket set and 1/2" drive ratchet.
- Reinstall locking tools and confirm timing marks realign.
- If marks donāt align, stop and correct it before reassembly.
Step 12: Reinstall the front cover and crank seal
- Install a new front crank seal as required by your kit. Use the correct installer from your timing tool kit (specialty) if included.
- Apply RTV silicone sealant only at Ford-specified joints (typically cover-to-head/block junctions).
- Install the front cover and bolts using a socket set.
- Torque to Ford spec using a torque wrench in an even pattern.
Step 13: Reinstall crank pulley, belt, mount, and valve cover
- Install the crank pulley and a new crank bolt using a torque wrench and torque angle gauge (specialty): Torque to Ford spec.
- Reinstall the serpentine belt using the serpentine belt tool (specialty).
- Reinstall the right engine mount using a socket set: Torque to Ford spec (TTY/angle where specified).
- Install the valve cover with a new gasket using a torque wrench: Torque to Ford spec (do not overtighten).
Step 14: Refill fluids and reassemble remaining parts
- Refill coolant to the correct level.
- If drained, refill engine oil and install a new filter using the appropriate tools from your socket set.
- Reinstall the fender liner, wheel (use a torque wrench on lug nuts), and lower the vehicle.
ā After Repair
- Start the engine and let it idle. Listen for abnormal rattling from the timing cover area.
- Check for oil leaks at the front cover and crank seal area.
- Top off coolant after the thermostat opens and the level stabilizes.
- If you get a check engine light, stop and scan for codesāincorrect timing or a missed connector can trigger it.
