The Hvac Heater Hose in your INFINITI provides a path for heated, pressurized coolant to travel to the vehicle's heater core from the engine. The flexible, thick material used to make a Hvac Heater Hose is tough and made to last. It's designed to handle hot coolant within the hose, and can stand up to grime, dirt, and drastic temperatures on the exterior. It can also absorb vibrations caused by the engine.

However, the repeated contact with high-temperature coolant can wear down the rubber on your Hvac Heater Hose and create weak spots in the inner lining, causing it to disintegrate or crack. These holes can leak coolant and damage your engine cooling system. The Hvac Heater Hose may also stiffen and break due to aging, causing splitting or cracks. Telltale signs of a heater hose in need of replacement include overheating, coolant leaks, or heater core issues.

A Hvac Heater Hose can vary in length depending on what kind of vehicle you drive. Purchasing one that's made for your exact model and year guarantees that the hose length isn't too long, and therefore obtrusive, but has enough length 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're familiar with more technical auto repairs, or you can contact your local service shop Before replacing the heater hose, you'll want to put a drain pan beneath the INFINITI to catch any remaining coolant within the hose. Another tip before you begin: make sure the engine has been turned off a while. For safety reasons, avoid installing a heater hose with a hot engine.

Here are general Hvac Heater Hose installation steps — make sure to consult your manual for detailed instructions. First, drain the coolant by twisting open the drain valve. Then undo the rubber seal by using a screwdriver, pliers, or a sharp pick and twist off the hose from the engine and heater core. Remove the old Hvac Heater Hose and install the new one. Make sure to add a little bit of sealant as too much can clog the hose. Finally, add coolant.

An important thing to remember for home mechanics: 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 create overheating, a noticeable waterfall noise in the back of your dashboard, or a host of other problems. If you're not an advanced mechanic, think about bringing your INFINITI to the experts.
