A Detailed Guide to the Radiator for the 2016-2024 Nissan Murano
Understand the signs of a failing radiator and learn how to choose the right replacement for your Murano.
- The radiator is critical for both engine and CVT transmission cooling in the Murano.
- Symptoms include overheating, visible coolant leaks (blue/green fluid), and a constantly low coolant level.
- High-quality aftermarket brands like Denso offer OEM-level performance for a much lower price than dealer parts.
- Always replace the radiator cap, thermostat, and consider replacing hoses at the same time for a complete repair.
Is Your Murano's Radiator Failing?
A failing radiator can lead to serious engine damage if ignored. The most common reasons for failure on the 2016-2024 Murano are cracks in the plastic side tanks, leaks from the seams where the plastic meets the aluminum core, or internal clogs from old coolant. Watch for these key symptoms:
- Engine Overheating: The temperature gauge on your dashboard climbing into the red is the most obvious sign.
- Visible Coolant Leaks: You may see puddles of sweet-smelling green or blue fluid under the front of your vehicle. Leaks often start small and can be seen as white or colored crusty residue on the radiator itself.
- Low Coolant Light: A frequent need to top off your coolant reservoir indicates a leak somewhere in the system.
- A/C Issues: In some cases, a faulty cooling fan control unit can cause both overheating and warm air from the A/C, especially in slow traffic. 🎬 Watch: Diagnosing overheating caused by faulty cooling fan units.
Known Issues, Recalls, and Service Bulletins
While there are no specific recalls for the radiator on the 2016-2024 Nissan Murano, it's important to be aware of related issues. The cooling system is tied to the transmission, and Nissan has issued Technical Service Bulletins (TSBs) for other models that highlight potential issues. For example, TSB NTB15015F mentions that when a CVT is replaced, debris can contaminate the system, and it is critical to flush or replace the radiator and external cooler to protect the new transmission. This shows how vital a clean, functioning radiator is for your Murano's transmission health.
Choosing the Right Aftermarket Radiator
When replacing your Murano's radiator, you don't have to buy the expensive dealership part. High-quality aftermarket options can provide the same performance for a fraction of the cost. Here’s a breakdown of the available brands:
- OEM-Equivalent Brands (Denso): Denso is a well-respected manufacturer that often supplies original parts to Nissan. Choosing a Denso aftermarket radiator is the closest you can get to OEM quality and fit without the OEM price. They are known for their reliability and are a top choice for many mechanics.
- Quality Aftermarket (CSF Radiator, Spectra): Brands like CSF have a strong reputation for producing quality radiators that meet or exceed original specifications. Spectra is a widely available brand, though online reviews are mixed; some users report good experiences while others have faced issues with leaks or fitment after a couple of years.
- Budget-Friendly Options (Global Parts): These radiators are the most affordable but may not have the same long-term durability or precise fit as more established brands. They can be a viable option if budget is the primary concern.
Pro Tip: Check the Transmission Cooler Fittings
The 2016-2024 Murano radiator includes a cooler for the CVT transmission fluid. When you receive your new aftermarket radiator, double-check that it comes with the correct fittings for the transmission lines to ensure a leak-free installation.

Frequently Asked Questions
Should I replace my radiator hoses and thermostat at the same time?
Yes, it is highly recommended. The cooling system is already drained and disassembled, making it the perfect time to replace these inexpensive but critical wear items. Old hoses can become brittle and fail, and a faulty thermostat can cause overheating.
What kind of coolant should I use in my 2016-2024 Murano?
Always use the coolant specified by Nissan for your vehicle, which is typically a blue-colored, long-life Asian vehicle coolant. Using the wrong type can cause corrosion and damage to the cooling system. Never mix different colors or types of coolant.
Do I need to replace the radiator cap?
Yes. The radiator cap is a pressure-regulating valve that is crucial for the system to work correctly. A weak or faulty cap can cause coolant to boil over at a lower temperature, leading to overheating. 🎬 See how to troubleshoot a P1217 engine overheat code. It's an inexpensive part that should always be replaced with the radiator.
Can I perform this replacement myself?
If you have moderate mechanical experience and the right tools, a radiator replacement is a feasible DIY project. It requires draining the cooling system, removing several components for access, and disconnecting fluid lines. Using a vacuum-fill tool to refill the coolant is recommended to prevent air pockets in the system.
