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

The HVAC Heater Hose in your allows high temperature, pressurized coolant to travel to the vehicle's heater core from the engine. The strong rubber that makes the HVAC Heater Hose is durable and long-lasting. It can withstand having high temperature liquid within the hose, and can withstand gunk, debris, and excessive heat or cold on its outer hose. It can also tolerate engine vibrations.

While it's designed to withstand extreme conditions, over time the constant exposure to hot coolant can wear on the rubber on your HVAC Heater Hose and cause the inner lining to deteriorate or crack. These holes can leak coolant and cause damage to the engine's cooling system. The HVAC Heater Hose may also stiffen and break due to aging, causing splitting or larger breaks. Common symptoms of a heater hose that's been compromised include overheating, leaking coolant fluids, or issues with your heater core.

If you're ready to replace a compromised or aging HVAC Heater Hose on your INFINITI EX35, INFINITI EX37, INFINITI FX35, INFINITI G25, INFINITI G35, INFINITI G37, INFINITI G37X, or INFINITI Q40, make sure to buy one that is the right size. An HVAC Heater Hose varies in length depending on what kind of vehicle you drive. Getting the correct size guarantees that the hose length isn't too long, and blocking other components, but still long enough to connect to the heater core.

Thinking about replacing the hose on your own? You may be able to install the heater hose yourself if you have a background in automotive repair, or you can contact your local service shop to install a new hose. Before replacing the heater hose, make sure to have a drain pan beneath the INFINITI to catch any remaining coolant within the hose. You also want to ensure your engine is completely cooled. 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. You'll want to start by draining any remaining coolant by twisting open the drain valve. Then loosen the rubber seal with pliers, a screwdriver, or a sharp pick and twist off the hose from each end. Remove the old HVAC Heater Hose and screw on the new hose. Be sure to use a small amount of sealant when installing, because too much can create clogging issues. As the last step, simply make sure to add coolant.

One note for DIYers, INFINITI cooling systems can be difficult to get all of the air out once the coolant has been drained. If there are air pockets in the cooling system, it could result in the engine overheating, a waterfall sound behind the dashboard, or several other problems. If you don't have advanced experience, you may want to bring your INFINITI to a professional.
