Your Nissan’s radiator is an essential auto part. While the motor works hard to keep your Nissan moving, your radiator cools the engine. This system safeguards the engine from overheating and the damage that can follow. Your Nissan radiator is made up of many supporting parts, including the Radiator Insulator.

The outside edges of your radiator likely have a Radiator Insulator on them. Each is made of a durable material so that they absorb vibrations and shocks when you run into bumps, potholes, or other on-the-road issues. The Radiator Insulator can handle the wide temperature range around the engine and help hold your Nissan radiator securely in place.

The Radiator Insulator can weaken out after miles and miles of wear since it's constantly shielding your radiator from vibrations while you're driving. Insulators can degrade with years of use, underhood heat from the engine, or break if the vehicle’s front end is damaged in an incident. 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 angling between all the different under-the-hood parts. We advise leaving the installation of new radiator insulators to authorized technicians. If you do choose to tackle the repair on your own, ensure that your Nissan is completely turned off and has had sufficient time to cool since the radiator can become very hot when in use. Then, turn to your Nissan manual for vehicle-specific information.

Support your radiator performance by addressing a broken or old Radiator Insulator quickly. Radiator insulators can come in many different sizes, so make sure you buy one that fits your vehicle. Protect your Nissan's performance with fine-tuned OEM parts from Nissan Parts crafted just for your model and trim.

This Radiator Insulator, part 215078J001, works with Nissan Maxima 2004-2021, Nissan Quest 2004-2009, or Nissan Rogue 2014-2019. Check the What This Fits tab for additional fitment info.
