The Hvac Heater Hose in your INFINITI provides a path for heated, pressurized coolant to move from the engine to the heater core. The flexible, thick material used to make a Hvac Heater Hose is heat-resistant and reliable. It's engineered to hold extremely hot liquid within the hose, and can stand up to grime, dirt, and drastic temperatures on its outer hose. It's also designed to remain securely in place, despite engine vibrations.

While it's designed to withstand extreme conditions, the repeated contact with hot liquid can degrade the material on the Hvac Heater Hose and create weak spots in the inner lining, causing it to disintegrate or break. These holes can leak coolant and cause damage to the engine's cooling system. The Hvac Heater Hose can also become brittle with age, causing splitting or larger breaks. Noticable signs of a heater hose in need of replacement include overheating, leaking coolant, or issues with your heater core.

If you're looking to replace a broken or aging Hvac Heater Hose on your INFINITI QX56 2004-2010, make sure to buy one that's made to fit your vehicle. A Hvac Heater Hose has different length sizes from vehicle to vehicle. Getting the correct size guarantees that the hose length isn't too long, thereby getting in the way of other components, but has enough length to plug into the heater core from the engine.

You may swap out the heater hose yourself if you have a background in automotive repair, or you may want to hire an experienced professional for installation. you'll want to put a drain pan underneath the INFINITI to catch coolant in the hose. Another tip before you begin: make sure the engine has been turned off a while. Never replace a heater hose if your engine is still hot.

General Hvac Heater Hose replacement steps are as follows. First, drain the coolant by unfastening the drain valve. Then, peel back the rubber seal with a sharp pick, pliers, or a screwdriver before you unscrew the tube from both ends. Twist on the new one. Add a small amount of sealant when installing, as too much can clog the hose. Finally, refill the coolant.

An important thing to remember for home mechanics: INFINITI 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 create overheating, a sound of water falling right behind your dashboard, or several other problems. If you don't have advanced experience, consider leaving the INFINITI hose replacement to an experienced professional.
