The radiator inside your Nissan is an essential auto part. While your engine is working to keep your vehicle running smoothly, your radiator keeps your vehicle cool. This prevents your Nissan from overheating or experiencing engine failure. Your Nissan radiator is made up of many supporting parts, including the Radiator Insulator.

There's usually a Radiator Insulator on each side of an engine radiator. Each is made of a durable material so that they absorb vibrations and shocks when you run into bumps, rough roads, or other on-the-road issues. A Radiator Insulator can withstand varying temperatures under your hood and support your Nissan radiator's positioning.

The Radiator Insulator can weaken out after miles and miles of wear as it is constantly working to dampen vibrations when your Nissan engine is running. Insulators can begin to fall apart after so many years, crack from engine heat, or break if you're in a front-end collision. If you notice coolant leaks or hear clunking noises when driving over bumps, you might want to examine the radiator and look to install a replacement Radiator Insulator.

Replacing a Radiator Insulator on your own is not impossible, but it usually requires some tough maneuvering around the many parts under your vehicle’s hood. We suggest letting a professional Nissan technician install replacement radiator insulators. If you do choose to tackle the repair on your own, ensure that your Nissan is completely turned off and has had adequate time to cool down. Radiators get very, very hot! Then, read your Nissan manual for instructions tailored to your Nissan Rogue 2008-2020 or Nissan Rogue Sport 2017-2020.

Support your radiator performance by addressing a worn out or missing Radiator Insulator as soon as possible. There are different insulator sizes for different vehicles, so make sure you buy one that fits your vehicle. Help your Nissan perform its best with fine-tuned manufacturer-made products from Nissan Parts engineered for your model and year.
