🔧 Renegade - Timing Chain Replacement

Your Renegade’s 2.4L engine uses a timing chain, not a timing belt. If the chain, guides, or tensioner are worn, you can get rattling at startup, cam/crank correlation codes, or poor running—replacement is a major front-of-engine tear-down.

Difficulty Level: Advanced | Estimated Time: 6-10 hours

Assumption: Stock 2.4L Tigershark timing chain set replacement.

⚠️ Safety & Precautions

• ⚠️ Support the vehicle with jack stands on solid, level ground.
• ⚠️ Disconnect the negative battery cable to prevent accidental cranking.
• ⚠️ Let the engine cool fully before draining coolant.
• ⚠️ Do not rotate the crankshaft with the chain removed; valve timing can be lost.
• ⚠️ Use an engine support bar before removing the passenger-side engine mount.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Disconnect the battery using a 10mm socket on the negative terminal.
• Plan for a clean work area—dirt in the timing cover area can cause leaks.
• Have your timing locking tools ready (these hold the cams/crank in place so timing can’t slip).

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise the vehicle and access the crank pulley area

• Use a floor jack rated 3-ton minimum to lift the front and set it on jack stands rated 3-ton minimum.
• Remove the right-front wheel using a 19mm socket.
• Remove the right inner splash shield fasteners using a trim clip removal tool and 8mm socket.

Step 2: Drain fluids

• Place a drain pan 10-quart under the radiator drain and drain coolant.
• Drain engine oil using a 13mm socket (oil pan drain plug), then remove the oil filter.
• Clean spills now to avoid slipping.

Step 3: Remove the serpentine belt

• Rotate the belt tensioner using a serpentine belt tool 3/8-inch drive and slip the belt off.
• If the belt shows cracks/glazing, replace it during reassembly.

Step 4: Support the engine and remove the passenger-side engine mount

• Install the engine support bar and take the weight of the engine.
• Remove the mount and bracket hardware using socket set metric 15mm-18mm and E-Torx socket set E10-E18 as equipped.
• Torque to OEM specification from the service manual during reassembly (mount bolts are safety-critical).

Step 5: Remove the crankshaft pulley (harmonic balancer)

• Remove the crank bolt using a breaker bar 1/2-inch drive and appropriate socket set metric.
• Use a harmonic balancer puller kit to pull the pulley off evenly.
• Never pry against the timing cover sealing surface.

Step 6: Remove the front timing cover

• Remove cover fasteners using socket set metric 8mm-13mm and E-Torx socket set E10-E18.
• Carefully separate the cover; use a gasket scraper plastic only if needed.
• Clean mating surfaces using brake cleaner and shop rags.

Step 7: Set cylinder #1 to TDC and lock timing

• Rotate the engine by hand at the crank using a socket set metric and breaker bar 1/2-inch drive until the timing marks align at TDC.
• Install the timing tool kit camshaft and crankshaft locking (specialty) (locking tools physically hold the shafts so timing can’t move).
• Do not rely on paint marks alone.

Step 8: Remove the tensioner, guides, and timing chain

• Remove the chain tensioner using the correct socket set metric.
• Remove chain guides using socket set metric 10mm-13mm.
• Remove the timing chain and note routing and timing marks.

Step 9: Install new guides, chain, and tensioner

• Install new guides using socket set metric; Torque to OEM specification from the service manual.
• Install the new chain, aligning the colored links to the sprocket timing marks (follow the kit instructions exactly).
• Install the new tensioner using socket set metric; Torque to OEM specification from the service manual.
• Release/activate the tensioner per the tensioner design (some are pinned and then released).

Step 10: Verify timing by hand-rotating the engine

• Remove locking tools only when the procedure allows, then rotate the crankshaft two full turns by hand using a breaker bar 1/2-inch drive.
• Re-check that timing marks realign correctly at TDC.
• If marks do not align, stop and correct timing before reassembly.

Step 11: Reinstall the front timing cover

• Install a new crank seal and timing cover gasket as applicable.
• Apply RTV silicone gasket maker only at OEM seam/joint points (typically where castings meet).
• Install the cover fasteners using torque wrench 3/8-inch drive; Torque to OEM specification from the service manual.

Step 12: Reinstall crank pulley, mount, belt, and shields

• Install the crank pulley and crank bolt using a torque wrench 1/2-inch drive; Torque to OEM specification from the service manual.
• Reinstall the engine mount/bracket using E-Torx socket set and socket set metric; Torque to OEM specification from the service manual.
• Install the serpentine belt using the serpentine belt tool 3/8-inch drive.
• Reinstall splash shield with 8mm socket and wheel with 19mm socket.

Step 13: Refill fluids and reconnect the battery

• Refill engine oil using a funnel and install a new oil filter.
• Refill coolant using a funnel.
• Reconnect the battery negative terminal using a 10mm socket.

✅ After Repair

• Start the engine and listen for abnormal rattles; a brief initial tensioner fill noise can be normal.
• Check for oil leaks at the timing cover and crank seal area.
• Bring the engine to operating temperature and recheck coolant level after it cools.
• If a check engine light appears, scan for codes—cam/crank correlation codes mean timing is still off.
