Your INFINITI's Hvac Heater Hose allows high temperature, pressurized coolant to move from engine to heater core. The rubber material that forms the tube of the Hvac Heater Hose is heat-resistant and reliable. It's designed to handle high temperature liquid flowing through the hose, and can handle sludge, muck, and extreme heat or cold on its outer hose. It can also remain securely in place, despite engine vibrations.

While it's designed to withstand extreme conditions, the frequent flow of hot coolant can wear on the rubber material on the Hvac Heater Hose and create weak spots in the inner lining, causing it to disintegrate or crack. When the inner lining cracks it can lead to a coolant leak and cause damage to the cooling system in your engine. The Hvac Heater Hose may also stiffen and break with age, causing splitting or cracks. Noticable signs of a heater hose that's been compromised include your engine overheating, leaking coolant fluids, or problems with the heater core.

If you're looking to replace a compromised or aging Hvac Heater Hose on your INFINITI EX35 2008-2017, INFINITI EX37 2013-2017, INFINITI FX35 2009-2012, INFINITI FX37 2013, INFINITI FX50 2009-2013, INFINITI M37 2011-2019, INFINITI M56 2011-2019, INFINITI Q50 2014-2019, INFINITI Q70 2011-2019, or INFINITI QX70 2014-2017, check that you're buying one that is the right size. A Hvac Heater Hose varies in length depending on what kind of vehicle you drive. Finding one that's the right size for your vehicle guarantees that the hose length isn't too long, and blocking other components, but has enough length to be inserted into your vehicle's heater core.

You may be able to replace the heater hose yourself if you're familiar with more technical auto repairs, or you can contact your local service shop for installation. place a drain pan underneath the INFINITI to catch any remaining coolant within the hose. Additionally, you'll want to ensure that the engine has been turned off a while. For safety reasons, avoid installing a heater hose if your engine is still hot.

To get started, follow these general Hvac Heater Hose replacement steps (consult your owner's manual for complete details). Start by draining the coolant by unfastening the drain valve. Then loosen the rubber seal with pliers, a screwdriver, or a sharp pick before you unscrew the tube from the engine and heater core. Twist on the new one. Add a small amount of sealant as too much can clog the hose. Finally, refill your coolant.

One note for DIYers, INFINITI cooling systems may be hard to get all of the air out after draining the coolant. It's vital to avoid having air pockets in the cooling system as it could lead to an overheated engine, a noticeable waterfall noise in the back of your dashboard, or a number of other issues. If you don't have advanced experience, think about bringing your INFINITI to a professional.
