2021-2025 Acura TLX Radiator Support: A Guide to the 2.0L and 3.0L Type S Differences
This essential guide covers the critical differences between the radiator supports for the 2.0L and 3.0L Type S engines, including part numbers, inspection tips, and replacement costs.
- The most critical factor is engine compatibility: Part 60400-TGV-A00ZZ is for the 2.0L engine ONLY and will not fit the 3.0L V6 Type S.
- Failure is always due to collision damage; symptoms are visual, such as misaligned panels and a hood that won't latch.
- When buying used, inspect carefully for cracks, bends, and signs of previous repair. A straight, undamaged OEM used part is often a better value than a new aftermarket part.
- Replacement is a complex, labor-intensive job (4-6 hours) that requires removing the entire front bumper and cooling system.
Symptoms of a Damaged Radiator Support
Unlike a mechanical part, a radiator support doesn't wear out over time. Failure is almost always the result of a front-end collision or a significant impact from underneath, like hitting a large piece of road debris. The symptoms are usually visible and related to the damage.
- Misaligned Body Panels: The most common symptom is a poor fit of the front-end parts. You may notice uneven gaps between the hood and fenders, or the front bumper cover may appear crooked.
- Hood Latch and Headlight Issues: Difficulty latching or unlatching the hood is a strong indicator of a bent or broken support. Your headlights might also seem aimed incorrectly or sit unevenly in their openings.
- Visible Cracks or Bending: A visual inspection may reveal obvious cracks, bends, or warping in the steel structure of the support itself. Look for damage around the mounting points for the radiator and headlights.
- Cooling System Problems: If the support is pushed back, it can damage the radiator or A/C condenser, leading to coolant or refrigerant leaks. In severe cases, a shifted radiator can reduce airflow, causing the engine to overheat.
Warning: A damaged radiator support can compromise the structural integrity of your vehicle's front end and the performance of its safety systems in a future collision. It should be inspected and replaced if damage is found.
Known Issues, Recalls, and TSBs
As of mid-2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Acura related to defects or premature failure of the radiator support itself on the 2021-2025 TLX. Failures are exclusively linked to physical damage.
However, the 2021-2025 TLX has been subject to several other recalls that owners should be aware of:
- Fuel Injection Software (Type S): A recall was issued for certain 2021-2025 TLX Type-S models for a software error that could cause an engine stall.
- Brake Pedal Pin: A recall affects 2021-2025 TLX models where the brake pedal pivot pin may not have been secured properly, potentially allowing the pedal to shift out of position.
- Fuel Tank Weld: Some 2021-2023 TLX vehicles were recalled for an improper weld on the fuel tank, which could result in a fuel leak.
- Passenger Airbag Sensor: A recall was issued for the front passenger seat weight sensor, which could crack and fail to disable the airbag for a small occupant as intended.
It is always a good practice to check for open recalls using your vehicle's VIN on the NHTSA website.
The Ultimate Guide to Buying a Used 2021-2025 TLX Radiator Support
Because this part is only damaged in collisions, the market for used radiator supports is strong. A recycled OEM part can offer the same fit and performance as a new one for a fraction of the price. However, careful inspection is critical.
Key Compatibility Check
Critical Warning: The radiator support for the 2.0L engine is NOT interchangeable with the one for the 3.0L V6 Type S. They have different part numbers and are designed for different cooling system layouts and mounting points.
- 2.0L Engine Models: Use part number 60400-TGV-A00ZZ.
- 3.0L V6 Type S Models: Use part number 60400-TGZ-A02ZZ.
Always verify the part number and the engine of the donor vehicle before purchasing.
Physical Inspection Checklist
When buying a used radiator support, bring a straight edge and a flashlight. Here’s what to look for:
- Check for Cracks: Pay close attention to the corners and mounting points, especially where the headlights and radiator bolt on. Stress cracks can form from an impact even if the part looks straight.
- Look for Bends and Warping: Place a straight edge along all the flat surfaces of the support. Any significant gaps indicate the part is bent, which will cause major alignment issues with your hood, fenders, and headlights.
- Inspect All Mounting Tabs: Ensure all plastic clips, tabs, and metal mounting holes are intact and not broken off or elongated. A missing tab can cause rattles or a loose fit for attached components.
- Examine for Previous Repairs: Be wary of parts that show signs of repair. Look for evidence of welding, body filler (Bondo), or fresh paint that doesn't match the original black e-coat. A repaired support will not have the same structural integrity as an original one.
- Verify the Part Number: If possible, locate the original part number sticker or stamping on the part to confirm it matches 60400-TGV-A00ZZ for the 2.0L model.
Why Used OEM is Often Better Than New Aftermarket
For a structural part like this, a good-quality, undamaged used OEM part is often a better choice than a cheap new aftermarket one. OEM parts are made to exact factory specifications for material thickness, strength, and fit. While high-quality CAPA-certified aftermarket parts exist, they can sometimes vary in quality and fitment, potentially leading to installation headaches and alignment problems. A straight, verified OEM part from a reputable recycler is a known quantity.
Cost Breakdown
The cost to replace the radiator support can vary significantly based on the parts used and labor rates. This is a labor-intensive job.
| Item | Estimated Cost | Notes |
|---|---|---|
| New OEM Part | $255 - $385 | Price from Acura dealerships. MSRP is around $382, but discounts are common. |
| New Aftermarket (CAPA Certified) | $250 - $400+ | Prices vary widely by brand and supplier. Ensures a certain level of quality and fit. |
| Used OEM Part | $175 - $300 | A common price from an auto recycler. Offers the best value if the part is inspected carefully. |
| Shop Labor | $500 - $800 | Estimated at 4-6 hours. This job requires removing the front bumper, headlights, and entire cooling package (radiator, condenser). |
| Total Professional Replacement (with Used OEM Part) | $675 - $1,100 | This is the most common and cost-effective repair scenario. |
Replacement Overview & Difficulty
Replacing the radiator support on a 2021-2025 Acura TLX is a complex job best left to experienced DIY mechanics or a professional body shop. The part itself is bolted in, not welded, which simplifies the process slightly.
Difficulty Rating: 4 out of 5 (Difficult)
The general steps include:
- Disconnecting the battery.
- Removing the front bumper cover and grille assembly.
- Removing the headlights.
- Draining the engine coolant and disconnecting the radiator hoses.
- Evacuating the A/C system (requires special equipment) and disconnecting the condenser lines.
- Unbolting and removing the entire cooling module (radiator, condenser, fans).
- Unbolting the old radiator support from the vehicle's frame rails.
- Installing the new support and reassembling everything in reverse order.
- Refilling the coolant and recharging the A/C system.
Pro Tip: Before fully tightening the new support, loosely attach the fenders, headlights, and hood to check for proper alignment. Make small adjustments to the support's position as needed to ensure all panel gaps are even.
Frequently Asked Questions (FAQ)
Is this part the same as a radiator core support?
Yes, the terms "front body panel," "radiator support," "radiator core support," and "front bulkhead" are all used to describe the same structural component at the front of the vehicle.
Will a radiator support from a TLX Type S fit my base 2.0L model?
No, it will not fit. The 2.0L and 3.0L Type S models use different radiator supports with unique part numbers and mounting points to accommodate their different engine and cooling system packages. You must use the correct part for your specific engine.
Can a cracked or bent radiator support be repaired?
It is strongly recommended to replace a damaged radiator support rather than repair it. Because it is a critical structural component that affects safety and panel alignment, attempting to straighten or weld it can compromise its integrity. A replacement (new or a quality used part) is the correct fix.
Does the radiator support need to be painted?
No. New and used OEM radiator supports typically come with a protective black electro-coat (e-coat) finish from the factory. This is sufficient for corrosion protection, and the part is not visible once the bumper and other panels are installed, so color-matching is not necessary.
