The radiator in your Nissan Frontier 1998-2015, Nissan Leaf 2011-2017, Nissan Pathfinder 1996-2006, or Nissan Xterra 2001-2015 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. But the radiator isn't just one complete part. It's made up of many parts, including the Nissan 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, road debris, or other incidents while driving. The Radiator Insulator can handle the wide temperature range around the engine and help to keep your Nissan radiator firmly attached to its designated location.

Your Radiator Insulator can get old and break after a while as it is constantly working to dampen vibrations when your Nissan engine is running. Insulators can fall apart after so many years, crack from engine heat, or break if you're in a front-end collision. If you start seeing coolant leaks or hearing clunk-clunk sounds when traveling over bumps, these symptoms could mean it's time to examine the radiator and look to install a replacement Radiator Insulator.

It’s possible to replace a Radiator Insulator on your own, but it usually requires some tough navigation around your engine parts. We recommend leaving the installation of new radiator insulators to authorized technicians. Should you decide to take matters into your own hands, check that your Nissan engine is off and has sufficiently cooled off. The radiator can get extremely hot! Then, consult your Nissan owner’s manual for specific instructions tailored to your vehicle.

Extend the service life of your radiator by repairing a worn out or missing Radiator Insulator ASAP. 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.
