The HVAC Heater Hose in your provides a path for heated, pressurized coolant to move from engine to heater core. The flexible, thick material used to make a HVAC Heater Hose is tough and made to last. It's engineered to hold hot coolant inside its tube, and can stand up to grime, muck, and extreme heat or cold on its outer hose. It's also designed to remain securely in place, despite engine vibrations.

Despite its durability, the frequent flow of hot liquid can degrade the rubber material on the HVAC Heater Hose and create weak spots in the inner lining, causing it to disintegrate or break. When the inner lining cracks it can lead to a coolant leak and cause damage to the engine's cooling system. The HVAC Heater Hose may also stiffen and break with age, creating small splits or cracks. Telltale signs of a heater hose in need of replacement include an overheated engine, coolant leaks, or heater core issues.

If you need to replace a compromised or worn out HVAC Heater Hose on your INFINITI JX35 or INFINITI QX60, shop for one that's the correct fit. An HVAC Heater Hose varies in length depending on what kind of vehicle you drive. Finding one that's the right size for your vehicle ensures it's not overly long, and therefore obtrusive, but still long 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 may want to hire an experienced professional for installation. Prior to beginning, place a drain pan under your INFINITI to catch coolant in the hose. Additionally, you'll want to ensure that the engine has rested a while. Do not replace the heater hose if your engine is still hot.

Here are general HVAC Heater Hose installation steps — make sure to consult your manual for detailed instructions. Start by draining the coolant by opening up the drain valve. Then, peel back the rubber seal with a sharp pick, pliers, or a screwdriver and twist off the hose from both ends. Take the old HVAC Heater Hose and discard, then to install a new hose. Make sure to add a little bit of sealant when installing, because too much can create clogging issues. As the last step, simply make sure to refill your coolant.

One note for DIYers, INFINITI cooling systems may be tough to get all of the air out once you've drained the coolant. The trouble with air pockets in the cooling system is that it could create overheating, a sound of water falling right behind your dashboard, or several other problems. If you're not an advanced mechanic, you may want to bring your INFINITI to the professionals.
