- Custom-fitted, custom-designed, and durability-tested for your vehicle
The HVAC Heater Hose in your creates a secure way for hot, pressurized coolant to move from the engine to the heater core. The flexible, thick material that forms the tube of the HVAC Heater Hose is durable and made to last. It's designed to handle extremely hot liquid flowing through the hose, and can withstand gunk, muck, and excessive heat or cold on its outer hose. It's also designed to absorb vibrations caused by the engine.
However, the frequent flow of hot coolant can wear on the material on the HVAC Heater Hose and make the inside of the hose fall apart or fracture. Despite being small, these cracks can create coolant leaks and cause damage to the cooling system in your engine. The HVAC Heater Hose may also stiffen and break as it ages, causing splitting or tears. Noticable signs of a heater hose in need of replacement include overheating, leaking coolant, or problems with the heater core.
If you're ready to replace a compromised or old HVAC Heater Hose on your Nissan Frontier, Nissan Pathfinder, or Nissan Xterra, ensure you purchase one that fits your vehicle. An HVAC Heater Hose has different length sizes depending on what kind of vehicle you drive. Purchasing one that's made for your exact model and year guarantees that the hose length isn't too long, thereby getting in the way of other components, but has enough length to connect to the heater core.
You may be able to replace the hose if you have advanced automotive experience, or you can consult with a professional for help with installation. When it's time to install, first you'll want to put a drain pan beneath the Nissan to catch coolant in the hose. Additionally, you'll want to ensure that the engine has been turned off a while. Never replace 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 twisting open the drain valve. Then, peel back the rubber seal with a sharp pick, pliers, or a screwdriver before unscrewing the hose from each end. Remove and discard the old HVAC Heater Hose and twist on the new one. Be sure to use a small amount of sealant because a large amount can end up clogging the tube. Finally, refill your coolant.
One note for DIYers, Nissan cooling systems may be tough 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 sound of water falling right behind your dashboard, or a number of other issues. If you're not an experienced technician, you may want to bring your Nissan to the professionals.
