HVAC Heater Hose.

• Carries hot, pressurized coolant from the engine to the heater core
• Replacement is best done by a professional or those with advanced auto experience
• Custom-fitted, custom-designed, and durability-tested for your vehicle

Your INFINITI's HVAC Heater Hose provides a path for heated, pressurized coolant to move from the engine to the heater core. The strong rubber used to make a HVAC Heater Hose is heat-resistant and reliable. It's designed to handle high temperature liquid within the hose, and can stand up to grime, debris, and extreme heat or cold on its outer hose. Additionally, it's engineered to absorb vibrations caused by the engine.

Despite its durability, the repeated contact with hot coolant can wear on the rubber material on the HVAC Heater Hose and cause the inner lining to deteriorate or crack. These holes can leak coolant and cause damage to the cooling system in your engine. The HVAC Heater Hose can also become brittle as it ages, causing splitting or larger breaks. Telltale signs of a heater hose in need of replacement include your engine overheating, leaking coolant, or heater core issues.

If you're ready to replace a compromised or old HVAC Heater Hose on your INFINITI G35, make sure to buy one that's the correct fit. An HVAC Heater Hose varies in length depending on your make and model. 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 plug into the heater core from the engine.

Thinking about replacing the hose on your own? You may be able to install the heater hose yourself if you have advanced automotive experience, or you can consult with a professional for help. Before you get started, place a drain pan under your INFINITI to catch coolant in the hose. Another tip before you begin: make sure the engine has rested a while. For safety reasons, avoid installing a heater hose while the engine is 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 opening up the drain valve. Then loosen the rubber seal with pliers, a screwdriver, or a sharp pick before unscrewing the hose from the engine and heater core. Take the old HVAC Heater Hose and discard, then twist on the new one. Make sure to add a little bit of sealant on the new hose because a large amount can end up clogging the tube. Lastly, refill the coolant.

One note for DIYers, INFINITI cooling systems may be hard to get all of the air out once the coolant has been drained. It's vital to avoid having air pockets in the cooling system as 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 don't have advanced experience, consider leaving the INFINITI hose replacement to an expert.
