Acura Integra Radiator Replacement Guide for 2023-2024 Models
Keep your Integra's 1.5L turbo engine cool by understanding when and why you might need to replace your radiator.
- The modern Integra was released in 2023; this guide does not apply to older vehicles.
- No major recalls or TSBs exist for radiator failure on the 2023-2024 Integra, indicating good reliability.
- For modified or aggressively driven cars, a full-aluminum performance radiator from a brand like CSF is a recommended upgrade over the OEM plastic/aluminum design.
- Thicker performance radiators may not fit with some aftermarket cold air intakes, so verify clearance before buying.
Correcting the Model Years: 2023-2024 Acura Integra
First, it's important to clarify that the modern Acura Integra was reintroduced to the North American market for the 2023 model year. This guide applies specifically to the 2023, 2024, and newer Integra models, not any vehicles from 2018-2022. These cars share a platform with the 2022+ Honda Civic Si, so information about that vehicle's cooling system is also relevant.
Symptoms of a Failing Radiator
A faulty radiator can't be ignored. Driving with a bad one risks severe engine damage. Look out for these common signs:
🎬 Watch this video to learn more about radiator failure symptoms.- Engine Overheating: The most obvious sign. If the temperature gauge on your dashboard climbs into the red, especially in traffic, your radiator may not be working correctly.
- Coolant Leaks: Finding puddles of bright green, pink, or yellow fluid under the front of your car is a clear sign of a leak. The plastic end tanks on the radiator can become brittle and crack over time.
- Low Coolant Light: A constantly low coolant level, requiring frequent top-offs, points to a leak somewhere in the system.
- Visible Damage or Corrosion: Bent fins from road debris or rust-colored stains on the radiator core indicate a problem.
- Discolored Coolant: If the coolant in your overflow tank looks rusty or sludgy, it can mean internal corrosion is clogging the radiator.
Known Issues, Recalls, and Service Bulletins
As of early 2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Acura or the NHTSA related to radiator failure on the 2023-2024 Integra. The cooling system has proven reliable in its early years. However, some owners of the high-performance Type S model have reported failures of the coolant expansion tank, which is a separate part. Other recalls for these model years have focused on issues like the steering gearbox and driver's seat frame, not the cooling system.
Choosing the Right Aftermarket Radiator: OEM vs. Performance
When replacing the radiator on your Integra, you have a choice between a standard replacement and a performance upgrade.
Radiator Types
| Radiator Type | Construction | Best For |
|---|---|---|
| OEM-Style Aftermarket | Plastic end tanks with an aluminum core | Daily driving and direct, budget-friendly replacement. Quality is similar to the original factory part. |
| Performance (e.g., CSF, Koyorad) | Fully TIG-welded aluminum construction, often with a thicker, 2-row core. | Modified vehicles, track use, or spirited driving. Offers improved cooling efficiency and durability under high heat. |
Pro Tip: For a turbocharged car like the Integra, keeping temperatures in check is key to engine longevity. An all-aluminum performance radiator from a brand like CSF is a worthwhile upgrade if you have modified your car or engage in frequent spirited driving. CSF radiators for this platform feature a larger 2-row core and exclusive "B-Tube" technology for better heat transfer.

Frequently Asked Questions (FAQ)
Is it hard to replace the radiator on a 2023-2024 Integra?
Replacement is moderately difficult. It requires removing the front bumper and draining the cooling system. Access to some mounting bolts can be tight. It is feasible for a DIYer with some experience, but a professional shop can typically complete the job in 2-3 hours.
Do I need a special radiator for a manual or CVT transmission?
No. For the 1.5L Integra, the factory-style radiators do not include an integrated transmission oil cooler, so the same part fits both automatic (CVT) and manual transmission models.
Will an aftermarket performance radiator fit with my cold air intake?
Maybe not. Performance radiators from brands like Koyo and CSF are significantly thicker than the stock unit. This can cause clearance issues with larger aftermarket high-volume air intakes. Always check for compatibility before purchasing.
What else should I replace with the radiator?
It's a good practice to replace the upper and lower radiator hoses at the same time. Also, you will need to refill the system with new Honda/Acura Type 2 blue coolant.
