A malfunctioning purge valve damages the entire EVAP system, produces abundant vapors without any combustion, and releases toxic hydrocarbons from the tailpipe of a Ford F150.
Moreover, a worn-out valve affects the surrounding components of the engine. In addition, the truck idles roughly, and the drivers fail to start it on the first ignition.
How do you Change a Purge Valve on Ford F150? You can change a purge valve on a Ford F150 by removing the battery’s negative terminal and identifying the valve location near exhaust manifolds. Now, disconnect the vacuum lines and remove purge lines by pushing colored tabs inward. Then, hold the tabs with fingers, pull, and remove the purge valve with an 8mm socket. Now, adjust a new valve in an open spot, move it back and forth and fix bolts with a socket. Next, reinstall the hose connector, tabs, and vacuum line.
A failing valve displays the worst engine performance, the EVAP becomes weak, and acceleration decreases.
A notification light turns on while the valve stops in one state. In such conditions, replacement is a wise decision because it resolves all problems immediately.
What is the method to change a Purge Valve on Ford F150?
I have explained a step-wise guide to change the valve without any challenge.
It is the quickest method and takes around 15 to 25 minutes. On average, it can cost you approximately $200 to $250.
Disconnect the battery
The constant electric power is dangerous during such replacement procedures. In such conditions, turn off the ignition of your Ford F150.
Then, access the negative terminal of your engine battery. You can use a wrench of appropriate size, adjust it on the nut and rotate it anti-clockwise.
Then, hold the connector, pull it outwards, and remove it. You should make sure there is no electric supply in the engine and battery.
Identify the valve
Generally, you can locate the purge valve near the exhaust manifolds and other emission components. But, identify the exact location through the manual instructions.
In addition, follow the drive well on the drive side. It is better to check its presence near the brake booster.
Also, approach the master cylinder of the engine on your pickup truck. It exists on the rear side of this cylinder and connects with other gadgets.
Disconnect vacuum line and connectors
The vacuum hose is also known as lines and tubes. They are flexible due to their built-in design. Also, they work as a route among the exhaust manifold and other engine components.
They are a connecting passage for the control, storage, and maintenance of emitted vapors. These tubes are beneath the engine of your Ford F150.
Access the vacuum line and remove it from the lower side. Then, identify the electrical connector of the purge valve. It exists on the right corner of the connecting gadget.
Hold it manually and rotate anti-clockwise. Finally, keep the removed parts aside for future use according to their condition.
Remove purge lines & tabs
Approach the evaporation and emission control lines and remove them. These are the passage that stores vapors inside the combustion unit.
Also, the purge lines do not allow the removal of vapors in the atmosphere. The entire system contains green and white connecting points.
Moreover, they have connecting fittings, and you can remove them manually. In such conditions, remove the colored fittings by pushing the tabs inward.
You should adjust two to three fingers on them and pull them gradually. However, they are powerful fitting connections and require complex removal techniques.
But, take preventive measures during such procedures because negligence can break the tabs. These are fragile components that require extra care and control.
Also, slow and side-by-side movements result in the removal of these connectors.
Remove the purge valve
The EVAP components and mounting brackets removal make the procedure quick.
It is better to keep the gadget intact because the removal of broken parts is more challenging.
Access the two screws on either side of the purge valve. Also, use an 8mm socket and adjust it on the screws.
Now rotate the socket anti-clockwise and lose them. Hold manually and pull until a complete removal.
Install a new purge valve
The installation is opposite to the removal method. You should find an appropriate valve with a stable shape and connecting points.
Also, clean the installation spot for maximum stability and insertion. Moreover, hold the new valve upside down. Then, adjust it in the open section and move it back and forth.
You can install two bolts on either side of the valve and secure it firmly. Then, use a socket, adjust it on the bolts and fix them electrically.
Now, add the connector of the fuel hose and adjust it in the mounting tabs.
Now, slowly push with fingers and fix with hands. Then, adjust the colored purge lines and stabilize the connection.
Furthermore, reinstall the vacuum lines back in the system.
Then, combine the electrical connectors with the central electric system. Moreover, keep it near the braking system and master cylinder.
In addition, connect the negative terminal of your truck battery. Tighten the nuts with a wrench in a clockwise direction. Turn on the ignition and check the performance of the valve.
Why should you change a Purge Valve on a Ford F150?
A damaged and malfunctioning purge valve indicates its replacement. Leaving the item without significant changes leads to complex technical faults.
Rough idling of pickup truck
A broken canister valve results in the rough idling of a Ford F150. In addition, unresolved conditions result in frequent truck stalling.
It deprives engine efficiency of a stable state. Also, frequent vacuum leakage leads to such problems.
However, it requires immediate repairing, but frequent idling demands the replacement of the purge valve. Moreover, the leakage level determines the speed of idling.
Insufficient engine performance
The engine performance decreases due to a damaged valve. It cannot produce enough energy for appropriate acceleration.
Also, the gas pedal does not respond adequately.
In such circumstances, you cannot access the standard speed conditions of a Ford F150.
Moreover, the engine can stop while showing a notification in the cabin section.
In addition, the ineffective valve requires immediate replacement.
It ensures high engine performance with maximum speed conditions and smooth driving.
The engine light appears and indicates different problems. For example, a worn-out purge valve leads to fuel tank leakage in your Ford F150.
It can empty the tank and provide emergency notifications. However, the vapors cannot go back to the burning centers.
As a result, the system collects information that goes back into the engine control unit. The replacement of such broken valves prevents excessive fuel loss.
The purge valve handles, controls, and stabilizes the number of vapors in the EVAP system. But, it breaks due to wearing, excessive use, and accumulation of corrosion.
As a result, the level of vapors becomes uncontrollable, and the combustion center cannot accommodate them.
The toxic hydrocarbon moves out through the tailpipe. In such circumstances, you cannot troubleshoot the emission procedures.
Moreover, change the broken item with a high-quality and stable valve. Then, perform the emission testing and record vapor production.
Difficulty in start and acceleration
A smooth start and stable acceleration are prime functions of an F150 truck. But, excessive fuel leakage and abundant vapors affect the valve adversely.
External air enters the engine and mixes with fuel. The entire combustion procedure destroys, and you cannot start your truck on the first ignition.
Moreover, excessive fuel and air mixing in the cylindrical chambers of an engine damages the whole machinery. The vehicle does not start at all after such mechanical issues.
A few people start their truck despite the damaged canister valve. As a result, the ride becomes unstable, and you can never enjoy a smooth journey.
How long does a purge valve last on a Ford F150?
These purge valves are durable and last the life of a pickup truck.
But, they require maintenance and control conditions that prevent them from unnecessary damage.
They wear out due to excessive use, inappropriate handling, and pressurized conditions.
Moreover, they get stuck in a closed or open state. As a result, the vapors cannot move through the combusting compartments.
