2015-2018 Jeep Renegade Radiator Support: Decoding the 'Small Overlap' for Correct Fitment
This guide details how to identify the correct radiator support for your Renegade, diagnose damage, and avoid the common compatibility trap related to tow hooks.
- The most critical factor is compatibility: part number 68441497AA is for models WITHOUT tow hooks and is identified by a 'small overlap' or notch on the lower passenger side.
- A damaged radiator support will cause alignment issues with the hood, fenders, and headlights.
- Due to fitment precision, a verified-undamaged used OEM support is often a better choice than a new, cheap aftermarket part.
- Replacement is a complex, 4+ hour job that requires dismantling the entire front end and handling the A/C and cooling systems.
Symptoms of a Damaged Radiator Support
Since the radiator support is a structural part, signs of failure are almost always visible or related to the alignment of other components. Damage is typically caused by a front-end collision, but can also result from hitting a high curb or large road debris. Here’s what to look for:
- Misaligned Front-End Parts: The most common symptom is poor alignment of body panels. You might notice the gap between the hood and fenders is uneven, the hood is difficult to close or latch, or the headlights and bumper cover appear crooked.
- Visible Cracks or Damage: A visual inspection after removing the front bumper cover may reveal cracks, breaks, or warping in the plastic and steel structure, especially around mounting points.
- Overheating or Cooling Issues: If the support is bent or broken, it can push the radiator into the cooling fan or change its position, reducing airflow. This can lead to the engine running hotter than normal or overheating, especially in traffic.
- Unusual Noises: A loose, cracked, or broken support can cause rattling or clunking sounds from the front of the vehicle, particularly when driving on bumpy roads.
Pro Tip: After any front-end accident, no matter how minor, carefully inspect the radiator support. A bent support can cause long-term issues with panel fitment and may indicate other hidden damage.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
As of early 2026, there are no specific recalls or TSBs from Jeep or the NHTSA for the radiator support structure on the 2015-2018 Renegade. Most issues with this part are the result of physical damage rather than a manufacturing defect.
However, it is worth noting that many Renegade owners from this generation have reported issues with the radiator cooling fan assembly. Symptoms include a loud, failing fan motor or a fan that stops working entirely, which can lead to overheating and A/C problems. 🎬 Watch: How to fix a radiator fan that isn't working. While this is a separate part, it's a common point of failure in the cooling system that buyers should be aware of.
Buying a Used 2015-2018 Renegade Radiator Support
For a structural part like this, a used OEM component is often a better choice than a new aftermarket one due to superior fitment. Aftermarket supports can sometimes have misaligned holes or tabs that complicate installation. Here’s what to check before you buy.
The Critical Compatibility Check: Tow Hook vs. Non-Tow Hook
The most important factor when buying a radiator support for a 2015-2018 Renegade is whether the vehicle is equipped with front tow hooks. The vetted part numbers, 68287721AA and its replacement 68441497AA, are for models WITHOUT tow hooks.
This version is identified by what Mopar calls a "small overlap" on the bottom side. This refers to a small notch cut out on the right (passenger) bottom side of the panel. Before purchasing, compare your existing part to the seller's photos, paying close attention to this lower area to ensure a match.
Warning: Do not assume the parts are interchangeable. Installing a non-tow hook support on a vehicle with tow hooks (or vice-versa) will result in fitment issues with the bumper and other components.
Physical Inspection Checklist:
- Check for Cracks: Carefully inspect the entire part, especially around the headlight mounting areas, radiator mounting tabs, and where it bolts to the frame rails. Pay close attention to corners and joints between the plastic and metal sections.
- Look for Previous Repairs: Avoid any parts that show signs of plastic welding, excessive glue, or body filler (Bondo). These are signs of a previous, likely improper, repair that compromises structural integrity.
- Verify Straightness: Lay the support on a flat surface to check for any warping or twisting. Even a slight bend can make lining up the fenders, hood, and headlights impossible.
- All Tabs and Clips Intact: Ensure all small mounting tabs, clips, and guide holes are present and unbroken. These are crucial for securing wiring harnesses, hoses, and the bumper cover.
Cost Comparison
Prices for a 2015-2018 Jeep Renegade radiator support can vary significantly based on the source.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM (Mopar) | $950 - $1,500 | Highest quality and guaranteed fit, but very expensive. |
| New Aftermarket | $300 - $400 | More affordable, but may have fitment issues requiring modification. |
| Used OEM | $450 - $700 | A good balance of cost and quality, provided it's inspected for damage. |
| Shop Labor for Replacement | $350 - $500 | Labor costs can vary by shop and location. |
Replacement Overview
Replacing the radiator support is a complex job rated as a 4 out of 5 for difficulty. It is feasible for an experienced DIY mechanic but not recommended for beginners. The process involves dismantling the entire front of the vehicle.
- Disconnect the battery.
- Remove the front bumper cover and grille assembly. 🎬 Watch this guide on how to remove the front bumper cover.
- Remove the headlights.
- The A/C system must be evacuated by a professional before disconnecting the condenser lines.
- Drain the engine coolant. 🎬 See a step-by-step walkthrough of the radiator replacement process.
- Disconnect the radiator hoses, cooling fan wiring, and any other attached sensors or components.
- Unbolt and remove the radiator and A/C condenser assembly from the support.
- Unbolt the old radiator support from the vehicle's frame rails.
- Installation is the reverse of removal. The A/C system will need to be professionally recharged afterward.
Frequently Asked Questions (FAQ)
Does a damaged radiator support mean my Jeep's frame is bent?
Not necessarily. The radiator support is designed to absorb some impact and can be damaged without any damage to the main frame rails. However, if the support is severely damaged, the frame rails should be professionally measured to ensure they are still straight.
Can I use the radiator support for models WITH tow hooks on my non-tow hook Renegade?
No, the parts are not directly interchangeable. The lower section of the support is shaped differently to accommodate the tow hook hardware and bumper design. Using the wrong one will cause significant alignment problems.
Is the radiator support made of plastic or metal?
It is a composite part, made from a combination of steel for strength in key areas and high-strength plastic to save weight.
Why are my headlights aimed incorrectly after a minor accident?
This is a classic symptom of a bent radiator support. The upper part of the support holds the headlights in place, and if it's even slightly bent or twisted, it will throw off the headlight alignment.
