You need to relieve the fuel system's pressure

To relieve the fuel system's pressure on a 2005 PT Cruiser, follow these steps:

Firstly, remove the fuel cap and open the hood of the car. Remove the cover on the air filter housing and then remove the fuel pump relay from the fuse box. This is located behind and below the filter housing.

Now, start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.

At this point, you can raise the car's rear end and support it on jack stands. Unscrew and remove the drain cap on the tank and let the fuel drain into a gas can or a drain pan that can hold 16 gallons.

The next step is to disconnect the fuel vapour hose and then loosen the hose clamp for the fuel filler neck hose. Use a screwdriver to disconnect the hose from the fuel fill pipe.

Finally, raise a transmission jack under the tank to support it. If you only have a floor jack, place a piece of plywood on it to prevent damage to the tank.

Disconnect the negative battery cable

Disconnecting the negative battery cable is one of the first steps to take when changing the fuel filter on a 2005 PT Cruiser. Here is a detailed, step-by-step guide on how to do this:

Firstly, open the hood of your PT Cruiser and locate the negative battery cable. It is essential to identify the negative cable, as disconnecting the positive cable could result in electrical arcing and sparking, which can be dangerous. The negative cable will typically be marked with a minus sign or the letters "NEG" or "N". It will also usually be black, while the positive cable is often red. Once you have located and identified the negative battery cable, proceed to the next step.

Before you begin, ensure you have the appropriate tools and safety equipment. You will need a wrench or socket set to loosen and remove the battery cable, as well as safety gloves and goggles to protect your hands and eyes. It is also recommended to have a clean, dry cloth handy to wipe up any corrosion or residue that may be present on the battery or cable connectors.

Now, carefully loosen the nut or bolt that secures the negative battery cable to the battery terminal. You can do this by turning the wrench or socket counterclockwise. Be gentle and take your time to avoid any damage to the battery or surrounding components. Once the nut or bolt is loose, carefully remove it by hand and set it aside in a safe place.

At this point, you should be able to carefully lift the negative battery cable away from the battery terminal. Again, take your time and be gentle to avoid any damage. You may need to wiggle the cable gently to detach it from the terminal. Ensure that the cable is completely disconnected from the battery.

Finally, properly dispose of the old battery cable or store it safely if you plan to reuse it. Be sure to handle the cable with care, as it may still be connected to other components of your vehicle. Recycle the old battery cable according to your local regulations, or store it in a dry, safe place if you intend to reuse it.

Remember, working with batteries can be dangerous, so it is essential to follow these steps carefully and take the necessary safety precautions. If you are unsure or uncomfortable at any point, it is best to consult a professional mechanic or seek advice from a trusted source.
