The HVAC Heater Hose in your Nissan allows high temperature, pressurized coolant to flow from the engine to the heater core. The flexible, thick material that makes the HVAC Heater Hose is heat-resistant and made to last. It can withstand having high temperature liquid flowing through the hose, and can stand up to grime, dirt, and excessive heat or cold on its outer hose. It's also designed to remain securely in place, despite engine vibrations.
However, the frequent flow of high-temperature coolant can wear down the material on the HVAC Heater Hose and cause the inner lining to deteriorate or break. These holes can leak coolant and damage your engine cooling system. The HVAC Heater Hose may also stiffen and break as it ages, creating small splits or larger breaks. Common symptoms of a heater hose in need of replacement include an overheated engine, coolant leaks, or issues with your heater core.
If you're ready to replace a damaged or old HVAC Heater Hose on your Nissan Frontier or Nissan Xterra, shop for one that fits correctly. An HVAC Heater Hose has different length sizes depending on what kind of vehicle you drive. Finding one that's the right size for your vehicle ensures the hose is not too long, and blocking other components, but can still reach far enough to connect to the heater core.
You may swap out your heater hose if you're familiar with more technical auto repairs, or you can consult with a professional for installation. Before you begin, you'll want to put a drain pan underneath the Nissan to catch coolant in the hose. Additionally, you'll want to ensure that the engine has rested a while. For safety reasons, avoid installing a heater hose while the engine is hot.
Here are general HVAC Heater Hose installation steps — make sure to consult your manual for detailed instructions. Start by draining the coolant by unfastening the drain valve. Then undo the rubber seal by using a screwdriver, pliers, or a sharp pick before unscrewing the hose from both ends. Remove the old HVAC Heater Hose and screw on the new hose. Add a small amount of sealant as too much can clog the hose. As the last step, simply make sure to add coolant.
One note for DIYers, Nissan cooling systems may be hard to get all of the air out after draining the coolant. If there are air pockets in the cooling system, it could lead to an overheated engine, a waterfall sound behind the dashboard, or a host of other problems. If you don't have advanced experience, consider leaving the Nissan hose replacement to the experts.
