How Does the PCV System Work, and What Maintenance is Recommended for PCV Hose and PCV Valve on Hyundai Sonata?

The Positive Crankcase Ventilation (PCV) system leads blow-by gases and crankcase vapors into the intake manifold allowing them to mix with intake air then to be sucked into the combustion chamber and burned together air/fuel mixture. This system fresh air from the air filter housing is channeled through hoses into the crankcase, where the fresh air gets to mix with the blow-by gases before the intake vacuum sucks it through the PCV valve and into the intake manifold. High intake manifold vacuum under idle and part-throttle helps draw blow-by gases and crankcase emulsion vapor via the PCV valve and through the crankcase ventilation hose into the intake manifold while at the same time drawing fresh air through the air intake duct or air filter housing into the crankcase. While, there is no specific timing for checking free the PCV valve or the hoses, the system slowly becomes less efficient because of oily sludge deposits and crankcase pressure build-up, which leading to symptoms like leaking engine seals. PCV hoses should be checked during such maintenance activities as the change of the oil filter, air filter, fuel filter, or spark plug; where dirty, the hoses should be washed; where cracked or deteriorated, the hoses should be renewed. On all models, the PCV valve is fastened to the valve cover; it should also be checked and replaced, when needed.

Hyundai Sonata PCV Hose

The Hyundai Sonata PCV Hose is a simple rubber tube that allows crankcase vapors to flow to the intake so the engine can reburn them, controlling emissions and fuel economy. A spring-loaded valve is arranged inside each modern PCV system. This valve opens and closes as per manifold vacuum. Then, a PCV Hose connects this valve to the crankcase so pressure can escape harmlessly rather than forcing oil past gaskets. There are two location-specific styles of the hose molded to contour around nearby components and avoid exposure to heat as the hose might snake along either the driver or passenger side of the engine bay depending on the model year. Pieces with a direct fit replicate the original bends and diameter specified by Hyundai, whereas universal tubing may require trimming and can sag when heated. A cracked PCV Hose creates unmetered air that upsets the air fuel ratio. Therefore, it results in rough idle, higher oil consumption, and extra tailpipe pollutants. Timely replacement maintains a Hyundai Sonata's smooth running. To replace the hose, simply open the hood of your car, unclip the clamps, slip the new PCV Hose onto the valve and oil-pan tube, and secure it to factory brackets, avoiding hot manifolds. Changing the air filter is an easy job, and many owners swap out the inexpensive PCV Hose at the same time as preventive maintenance to delay Sonata issues for a few years.

If you are looking for affordable high-quality OEM Hyundai Sonata PCV Hose, then you have come to the prime place. Our website provides a large amount of genuine Hyundai Sonata PCV Hose at unbeatable prices. All our parts come backed with the manufacturer's warranty.
