STEP-BY-STEP ROUTING INSTRUCTIONS

Accurate belt routing is imperative to ensure the correct rotation direction of each accessory and to maintain proper belt tension. Deviations from the specified belt routing path can lead to system failure or premature component wear. Always reference the visual diagram provided and the following steps for precise installation. For diagnosing a failing serpentine belt, refer to our comprehensive guide on accessory drive system diagnostics.
Before You Begin:
Before attempting to route a new serpentine belt, ensure the engine is off and cool. Locate the automatic belt tensioner. For the 2013 Dodge Avenger 2.4L, this tensioner typically features a square recess (often 3/8″ or 1/2″) designed for a breaker bar or specific tensioner tool. Apply counter-clockwise pressure to rotate the tensioner arm and release the belt tension. This will allow removal of the old belt and installation of the new one.
Routing Sequence (Refer to Diagram for Pulley Identification):
1. Crankshaft Pulley (P1): Begin by routing the belt around the crankshaft pulley. This is the largest pulley at the bottom, directly connected to the engine’s output. Ensure the ribbed side of the belt sits correctly within the grooves.
2. A/C Compressor Pulley (P2): From the crankshaft, guide the ribbed side of the belt underneath the A/C compressor pulley. This component is typically located low on the passenger side of the engine compartment.
3. Idler Pulley (P3 – Lower): Proceed from the A/C compressor, routing the ribbed side of the belt over the top of the lower idler pulley. This pulley is smooth and serves to guide the belt and provide proper wrap angles around other accessories.
4. Alternator Pulley (P4): Next, route the ribbed side of the belt over the top of the alternator pulley. The alternator is generally located high on the driver’s side of the engine compartment. Ensure a secure fit in the grooves.
5. Power Steering Pump Pulley (P5 – if equipped/visible on 2.4L): If your 2.4L model includes a hydraulic power steering pump (some models may be electric, thus omitting this pulley), route the ribbed side of the belt underneath this pulley. Verify the presence of this component against your specific vehicle configuration. For 2013 2.4L Avengers, electric power steering is common, so this pulley may be absent. If so, skip this step.
6. Idler Pulley (P6 – Upper): Route the ribbed side of the belt over the top of the upper idler pulley. Similar to the lower idler, this smooth pulley aids in guiding the belt.
7. Belt Tensioner Pulley (P7): The final step involves routing the belt around the automatic belt tensioner pulley. With tension released (breaker bar applied), route the ribbed side of the belt underneath the tensioner pulley. This is often the last pulley to be routed as it allows for the slack needed to install the belt.
8. Release Tensioner: Once the belt is fully seated on all other pulleys, slowly release the pressure on your breaker bar or tensioner tool. The belt tensioner will automatically apply the correct tension to the serpentine belt.
9. Final Inspection: Before starting the engine, meticulously inspect the entire belt routing path. Confirm that the belt is perfectly seated in all pulley grooves, with no ribs misplaced or sections of the belt hanging loose. Check for proper alignment.
Never attempt to route the belt or work near rotating engine components while the engine is running or hot. Always disconnect the negative battery terminal before significant mechanical work to prevent accidental starts or electrical shorts. Ensure hands and clothing are clear of the belt and pulleys before starting the engine for the first time after installation.
TENSION & ADJUSTMENT NOTES

The 2013 Dodge Avenger 2.4L engine utilizes an automatic belt tensioner, eliminating the need for manual adjustment. This critical component maintains constant tension on the serpentine belt throughout its operational lifespan, compensating for belt stretch and minor variations. Understanding the function of the automatic belt tensioner is crucial; explore our article on tensioner replacement procedures for further insight.
Checking Tension:
While the tensioner is automatic, its proper function is vital. You cannot “adjust” the tension, but you can assess if the tensioner itself is failing.
1. Visual Inspection: Observe the tensioner’s movement. It should maintain a steady position with minimal vibration when the engine is running. Look for excessive oscillation or a tensioner arm that appears to be at either the extreme end of its travel range.
2. Alignment: Ensure the tensioner pulley is perfectly aligned with the other pulleys. Misalignment can indicate a worn tensioner bearing or a bent tensioner arm, leading to rapid belt wear and noise.
3. Belt Slack: With the engine off, apply firm pressure to the longest free span of the belt. There should be minimal deflection. Excessive slack, particularly accompanied by chirping or squealing noises upon startup or accessory load, suggests a failing tensioner.
4. Tensioner Indicator (if present): Some automatic tensioners feature an indicator mark on the tensioner body that aligns with a mark on the tensioner arm, indicating the operational range. Consult your service manual for your specific tensioner type. If the arm is outside this range, the belt tensioner or the belt itself may require replacement.
Common Tension Issues:
Squealing/Chirping: Often the most noticeable symptom, typically caused by insufficient tension due to a weak tensioner spring or worn tensioner pulley bearing. It can also indicate a glazed belt or contaminated pulley surfaces.
Premature Belt Wear: A tensioner that applies too little tension allows the belt to slip, generating excessive heat and abrasion. Conversely, a tensioner applying too much tension can prematurely wear accessory bearings (alternator, A/C compressor, power steering pump if equipped) due to constant high load.
* Vibration: A failing tensioner can cause unusual vibrations in the accessory drive system, sometimes transmitted into the vehicle cabin.
An automatic belt tensioner should ideally maintain a tension range that allows approximately 1/2 inch of deflection on the longest belt span under moderate thumb pressure. However, reliance on the tensioner’s visual indicator marks (if equipped) and overall operational smoothness is the primary method for evaluating its health. Replace the belt tensioner if it shows signs of excessive play, binding, or failure to maintain adequate belt tension.
FAQ
When should the serpentine belt be replaced on a 2013 Dodge Avenger 2.4L?
Manufacturer recommendations typically suggest inspection of the serpentine belt every 30,000 to 50,000 miles, with replacement every 60,000 to 100,000 miles or as needed. However, environmental factors and driving conditions can accelerate wear. Always perform a visual inspection for cracks, fraying, missing ribs, glazing, or any signs of material degradation. If you suspect issues with specific accessory components, such as the alternator or power steering pump, consult our dedicated troubleshooting resources.
What are the common symptoms of a failing serpentine belt or belt tensioner?
Common indicators include persistent squealing or chirping noises, especially on cold starts, when turning the steering wheel (if hydraulic power steering), or when the A/C is engaged. Other symptoms include visible cracks, fraying, or glazing on the belt surface, a flickering battery light (indicating alternator issues due to belt slip), or loss of power steering assist (if hydraulic). A seized or noisy tensioner pulley or a tensioner arm that is vibrating excessively also points to a problem.
Can I use a serpentine belt with a slightly different length than the OEM specification?
No, it is strongly advised to use a serpentine belt that matches the OEM specified length and rib count precisely. A belt that is too long may exceed the tensioner’s operational range, resulting in insufficient tension and slippage. A belt that is too short may over-compress the tensioner or may not even fit, placing excessive strain on accessory bearings and potentially leading to premature component failure. Adhering to the manufacturer’s belt part number and dimensions is crucial for proper function.
What tools are typically required for replacing the serpentine belt on this model?
For the 2013 Dodge Avenger 2.4L, the primary tool required is a breaker bar or a specific serpentine belt tool with a square drive (commonly 3/8″ or 1/2″) to release the tension on the automatic belt tensioner. Additionally, basic hand tools such as a ratchet and sockets may be needed if any covers or obstacles need to be removed to access the belt. A flashlight or work light is also beneficial for clear visibility of the pulley diagram and routing path.
What is the primary difference between a serpentine belt and a timing belt?
The serpentine belt (also known as the accessory drive belt) drives external accessories such as the alternator, air conditioning compressor, and power steering pump. It is typically visible and runs on the exterior of the engine. The timing belt, in contrast, is an internal engine component that synchronizes the rotation of the crankshaft and camshaft(s), ensuring precise valve timing. Failure of a serpentine belt will disable accessories, but engine operation will generally continue (until the battery dies); failure of a timing belt on an interference engine will typically cause severe internal engine damage. The 2013 Dodge Avenger 2.4L engine uses a timing chain, not a timing belt, for camshaft synchronization, which is a more durable, “lifetime” component that does not require regular replacement like a timing belt.
