The HVAC Heater Hose in your creates a secure way for hot, pressurized coolant to travel from engine to heater core. The rubber material that makes 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, debris, and excessive heat or cold on the exterior surface of the tube. It can also tolerate engine vibrations.

Despite its durability, the repeated contact with hot liquid can degrade the rubber material on the HVAC Heater Hose and make the inside of the hose fall apart or break. When the inner lining cracks it can lead to a coolant leak and hurt the integrity of the engine's cooling system. The HVAC Heater Hose can also become brittle with age, creating small splits or tears. Noticable signs of a heater hose in need of replacement include an overheated engine, leaking coolant, or issues with your heater core.

If you're looking to replace a broken or worn out HVAC Heater Hose on your INFINITI FX35 or INFINITI G35, shop for one that's made to fit your vehicle. 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 it's not overly long, and therefore obtrusive, but can still reach far enough to be inserted into your vehicle's heater core.

Thinking about replacing the hose on your own? You may be able to install the hose if you have a background in automotive repair, or you can consult with a professional for installation. Before you start, you'll want to put a drain pan under your INFINITI to catch any remaining coolant within the hose. You also want to ensure the engine has been turned off a while. For safety reasons, avoid installing a heater hose while the engine is hot.

General HVAC Heater Hose replacement steps are as follows. First, drain the coolant by twisting open the drain valve. Then, peel back the rubber seal with a sharp pick, pliers, or a screwdriver before you unscrew the tube from the engine and heater core. Remove the old HVAC Heater Hose and install the new one. Be sure to use a small amount of sealant as too much can clog the hose. Finally, add coolant.

One note for DIYers, INFINITI cooling systems may be hard 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 result in the engine overheating, a noticeable waterfall noise in the back of your dashboard, or a host of other problems. If you're not an advanced mechanic, you may want to bring your INFINITI to a professional.
