Detailed layout and routing guide for 2013 Dodge Journey 36 engine accessory belts

Follow the specific serpentine layout to ensure optimal tension and functionality of the front-end components powered by the V6 powertrain. Accurate placement around the alternator, water pump, power steering pump, and tensioner pulley is crucial to prevent slippage or premature wear.
Referencing the correct routing path will help maintain consistent performance and avoid unnecessary repairs caused by misaligned paths or improper pulley engagement. Each loop must be positioned to maximize belt life and component efficiency.
Utilize manufacturer-recommended routing schematics when replacing or inspecting the accessory drive loop. This will guarantee that all driven parts receive proper mechanical support, ensuring smooth operation under various load conditions.
Engine Serpentine Routing and Component Layout
To correctly install or inspect the accessory drive loop on this mid-size SUV with a V6 engine, follow the routing path below to ensure proper tension and function.
- The serpentine starts at the crankshaft pulley, which powers all auxiliary components.
- From there, it wraps around the alternator pulley to generate electrical charge.
- Next, it passes over the idler pulley, maintaining tension and alignment.
- The belt continues around the water pump pulley, essential for coolant circulation.
- Afterwards, it loops around the air conditioning compressor for climate control.
- Finally, it encircles the power steering pump pulley before returning to the crankshaft.
For accurate installation or replacement, consult the engine bay decal or a reliable repair manual specific to the vehicle’s engine code to confirm pulley positions and belt length. Use a belt tension gauge or the automatic tensioner adjustment method where applicable to maintain optimal belt tension and prevent slippage.
Routing Path for the Serpentine System

Begin the routing at the crankshaft pulley, ensuring the continuous loop wraps smoothly around the alternator pulley next. From there, guide the loop over the water pump pulley, followed by the tensioner to maintain proper tension and prevent slippage. Continue the path around the power steering pulley before looping over the idler pulley, which helps keep alignment precise. Finally, complete the circuit by returning the loop to the crankshaft pulley, verifying all grooves align with their corresponding pulleys for optimal performance.
Use the factory service manual’s routing chart for reference, but always confirm physical pulley orientation before installation. Misrouting can cause premature wear or accessory failure. When installing the serpentine system, apply tension via the automatic tensioner arm to maintain consistent pressure throughout the circuit. Double-check the routing visually to avoid contact with moving parts or sharp edges that could degrade the material.
Identifying Tensioner and Pulley Locations

Locate the automatic tensioner near the engine’s front center, typically mounted on a pivot arm with a spring mechanism to maintain optimal drive strap pressure. It is distinguishable by a smooth, round pulley that presses against the looped drive loop to regulate slack.
Accessory rollers, or idler wheels, are positioned along the routing path to guide and support the serpentine loop. These components usually appear as smaller, free-spinning discs without any direct drive function but crucial for maintaining proper alignment.
The crankshaft pulley serves as the main driving force at the base of the engine block, often the largest grooved wheel connected directly to the motor’s crankshaft. It powers the entire system by transmitting rotational energy through the loop.
Locate the alternator pulley on the upper section of the engine bay; it is connected to the alternator housing and usually smaller than the crankshaft wheel. The power steering and air conditioning compressor pulleys are positioned along the sides, identifiable by their proximity to respective pump units.
Consult service manuals or vehicle-specific repair guides for exact component placements, as slight variations may occur depending on engine configuration or optional equipment.
Steps to Replace the Serpentine Belt Correctly
Begin by disconnecting the negative terminal of the battery to ensure safety during the procedure. Locate the tensioner pulley and use a suitable wrench or serpentine tool to relieve tension by rotating it in the specified direction.
Once the tension is released, carefully slide the worn drive loop off the pulleys, noting its routing for correct installation of the new component. Inspect all related pulleys for wear or damage, including cracks, glazing, or misalignment, and replace any faulty parts before proceeding.
Position the new continuous loop over the crankshaft pulley first, then continue routing it around the remaining pulleys following the original path. Reapply tension by slowly releasing the tensioner, ensuring the new band seats properly without slack or twisting.
Verify correct alignment on all pulley grooves and confirm that the tensioner maintains appropriate pressure. Reconnect the battery and start the engine to observe proper operation and listen for unusual noises, indicating secure installation and smooth function.
