OEM Infiniti Radiators

Filter

The radiator is a critical part of your vehicle's cooling system, helping to regulate engine temperature and prevent overheating. Over time, components like the radiator hose and radiator cap can wear out, leading to leaks that may cause serious engine damage.

How Do You Check for Radiator Leaks in Your Infiniti Q50?

Checking for leaks in your Infiniti Q50's radiator is simple. Start by inspecting the radiator itself for visible cracks or corrosion. Next, check the radiator hose for signs of wear, such as cracks or bulging, as these can lead to coolant leaks. Finally, ensure the radiator cap is secure and free from damage—if it's loose or cracked, it can cause pressure loss and overheating. If you notice low coolant levels, puddles under your car, or an overheating engine, it's time for a closer look.

What Should You Do If You Find a Radiator Leak?

If you suspect a leak, addressing it quickly can prevent engine damage. Small leaks in the radiator hose or radiator cap may be fixed with replacements, while larger issues may require a new radiator. Running your Q50 with a compromised cooling system can lead to severe overheating, so acting fast is key.
