2018-2020 Mitsubishi Eclipse Cross Radiator Support: A Collision Repair Guide
Learn how to identify damage, choose the right replacement parts, and understand the complexities of this critical structural repair.
- This part is almost exclusively replaced due to collision damage; it does not fail from normal use.
- The radiator support is a multi-piece assembly, not a single part. Verify which components are included when purchasing.
- Fitment is critical for panel alignment. A used OEM part is strongly recommended over a new aftermarket part to ensure proper fit.
- Replacement is a complex job for a professional body shop, often requiring spot welding and dismantling the entire front of the vehicle.
- This part only fits 2018-2020 models. The 2022+ facelifted Eclipse Cross uses a different front-end structure.
Symptoms of a Damaged Radiator Support
Because the radiator support is a structural component, it does not fail from normal wear and tear. Damage is almost always the result of a front-end collision or significant impact. Symptoms are typically visual and straightforward.
- Misaligned Body Panels: The most common symptom is a front end that looks 'off'. You may notice uneven gaps between the hood and fenders, or that the headlights are no longer sitting flush and symmetrical.
- Hood Latching Issues: If the hood is difficult to close, won't latch securely, or pops open unexpectedly, it could be due to a bent radiator support that has moved the hood latch out of alignment.
- Visible Damage: After any front-end impact, visually inspect the support for cracks, bends, or broken welds. 🎬 Watch this video on repairing a damaged radiator support. The support is often made of a combination of steel and plastic components, all of which can be damaged.
- Cooling System Problems: While less direct, a damaged support can cause the radiator or A/C condenser to shift. This can put stress on hoses, leading to coolant leaks, or cause vibrations that damage the radiator itself over time, potentially leading to overheating. 🎬 Watch how to replace a damaged Mitsubishi radiator.
Warning: A damaged radiator support compromises the structural integrity of the front of your vehicle. It can affect crash performance and the security of components like the hood and bumper. Driving with a significantly damaged support is not recommended.
Buying a Used 2018-2020 Eclipse Cross Radiator Support
For collision repair, a quality used OEM radiator support is often the best value. It provides the exact fitment and material quality of a new factory part without the high cost. Aftermarket parts can have issues with fit, requiring modification that adds labor costs and can compromise structural integrity.
Inspection Checklist for a Used Part:
- Check for Cracks and Bends: Lay the support on a flat surface to check for any twisting or warping. Carefully inspect all corners and mounting points for hairline cracks, especially where it bolts to the vehicle's frame.
- Verify All Mounting Points: Ensure all tabs, brackets, and holes for the headlights, radiator, condenser, and bumper are intact and not broken off. Small plastic tabs are especially fragile.
- Look for Signs of Past Repairs: Avoid any parts that show signs of being previously repaired. Look for evidence of welding, body filler, or fresh paint in localized areas, which indicates it was salvaged from a wreck and repaired, not just removed.
- Confirm Part Completeness: The Eclipse Cross radiator support is an assembly of several pieces, including an upper tie bar, a lower tie bar, and side brackets. Confirm with the seller which pieces are included to ensure you get everything you need for your repair.
Pro Tip: When buying used, it's best to source the entire radiator support assembly from a single donor vehicle. This ensures all the interconnected pieces will align correctly.
Compatibility: Pre-Facelift Models Only
This radiator support assembly fits only the pre-facelift 2018, 2019, and 2020 Mitsubishi Eclipse Cross models. Mitsubishi performed a significant facelift for the 2022 model year, which included a completely redesigned front end. Parts for 2022 and newer models are not compatible. Dealer parts diagrams confirm that these components fit vehicles produced up to December 30, 2020.
Known Issues, Recalls, and Service Bulletins
As of mid-2026, there are no specific recalls or Technical Service Bulletins (TSBs) from Mitsubishi or the NHTSA related to the radiator support structure on the 2018-2020 Eclipse Cross. Recalls for this vehicle have focused on software for the Forward Collision Mitigation (FCM) and other electronic systems. Any issues with the radiator support would be related to collision damage, not a manufacturing defect.
Cost Comparison: New vs. Used vs. Aftermarket
The radiator support is a multi-piece assembly. Prices below reflect the approximate cost for the main structural components combined.
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM | $350 - $500+ | Purchased from a Mitsubishi dealer. This is for the main components; small clips and hardware are extra. |
| New Aftermarket | $150 - $250 | Available from various online retailers. Fitment can be inconsistent, potentially requiring modification. |
| Used OEM | $200 - $350 | Best balance of cost and quality. Sourced from a recycled vehicle. Price depends on condition and included components. |
OEM Part Numbers and Components
The radiator support is not a single part number but an assembly. Key OEM components for the 2018-2020 models include:
- Lower Tie Bar: 5256C062
- Left (Driver Side) Bracket: 5256C109
- Right (Passenger Side) Bracket: 5256C110

Note that other part numbers exist for various brackets and clips. Always verify compatibility with the seller using your vehicle's VIN.
Frequently Asked Questions (FAQ)
Is the radiator support a bolt-on or weld-in part?
The radiator support on most modern vehicles, including the Eclipse Cross, is a combination of bolt-on and weld-on sections. While some main brackets may bolt to the frame rails, replacing the full assembly correctly often requires drilling out factory spot welds and welding the new support in place. This is not a simple bolt-off, bolt-on job.
🎬 See this step-by-step radiator support replacement walkthrough.Can I drive my car with a damaged radiator support?
It is strongly discouraged. A damaged support compromises the structural integrity of the front end, can cause other components to shift or fail, and may make the vehicle unsafe in another collision. The hood latch may also be compromised, creating a risk of the hood opening while driving.
Will a cheap aftermarket radiator support work?
While it may be cheaper, aftermarket structural parts are notorious for poor fitment. This can lead to misaligned headlights, uneven panel gaps, and increased labor time for your body shop to make it fit. For structural integrity and proper panel alignment, a new or used OEM part is highly recommended.
Why are there so many different part numbers for the radiator support?
The radiator support is an assembly of multiple individual parts sold separately by the manufacturer, such as the lower tie bar and side brackets. This is why you will see several part numbers associated with it. When buying used, it's important to clarify which of these components are included.
