Disconnect the breather hose from the hard line on the right side of the inlet

Disconnecting the breather hose from the hard line on the right side of the inlet is a crucial step in removing the intake manifold of your 2005 WRX. This process can be challenging due to the complex arrangement of lines and hoses in the Subaru boxer engine.

To begin, locate the breather hose from the passenger side valve cover. This hose needs to be disconnected from the hard line on the right side of the inlet. It is advisable to loosen the turbo inlet clamp before attempting to disconnect the breather hose.

You will need specific tools for this task, such as a 3/8th socket set, including 8, 10, 12, and 14mm sockets, a 3/8th ratchet, extensions, and an assortment of pliers of various lengths for clamps and hose removal. Hose removal pliers or a set of fuel line disconnects can be particularly helpful for this step.

Once you have the necessary tools, carefully disconnect the breather hose from the hard line. Take your time and be gentle to avoid any damage to the hose or the surrounding components. Ensure that all associated hoses and wiring connected to the engine and manifold are also disconnected to prevent any issues.

Remove the turbo clamp

To remove the turbo clamp on a 2005 WRX, you will need to follow a series of steps to ensure a safe and effective removal process. Here is a detailed guide to assist you:

Firstly, it is important to gather the necessary tools and materials. You will need a range of socket sizes, including 8mm, 10mm, 12mm, 14mm, and potentially others, depending on the specific model and variations. It is also recommended to have a pry bar, jack, and jack stands if your car is lowered.

Now, let's begin the process:

  • Open the hood and remove the intercooler. Undo the BPV (if applicable) using the appropriate socket size.
  • Remove the clamps from the turbo inlet and intercooler pipe. This will involve breaking loose the bolts and then removing them.
  • Disconnect the vacuum lines from the actuator.
  • Detach the coolant line from the upper coolant tank that leads to the turbo.
  • Remove the oil feed banjo bolt, which is typically located on top, and be mindful of the washers.
  • Locate the mount bracket on the passenger/right side of the turbo and remove it.
  • Move to the left side of the turbo (driver side) and remove the coolant feed lines. Again, be mindful of the washers to avoid any mess.
  • With these steps completed, you should now have access to the turbo clamp. Remove any remaining bolts or clamps securing the turbo clamp in place.
  • Carefully wiggle or pry the turbo clamp loose, and slowly remove it from the turbocharger.

It is important to note that this is a general guide, and there may be slight variations depending on your specific model and modifications. Always refer to a trusted mechanic or a detailed model-specific guide if you encounter any challenges or uncertainties during the process.

Disconnect the brake booster vacuum hose

Disconnecting the brake booster vacuum hose on a 2005 WRX requires careful attention to detail, but it is a task that can be completed with the right tools and knowledge. Here is a step-by-step guide to help you through the process:

Firstly, it is important to relieve the pressure in the brake system before attempting any disconnections. To do this, pump the brake pedal several times to release the vacuum in the booster. This step will make it significantly easier to disconnect the hose and reduce the risk of any spillage or damage.

Now, locate the brake booster vacuum hose near the driver's side hardlines. You will need to remove the feed, return, and evap lines from these hardlines to access the vacuum hose connection. It is important to work carefully in this area, ensuring that you do not cause any accidental damage to surrounding components.

The vacuum hose is connected to the brake booster via a plastic connector with sharp barbs and a one-time-use factory clamp. Due to the presence of these barbs, it is not advisable to try and disconnect the hose itself from the connector. Instead, focus on carefully removing the connector from the booster. Using a set of hose removal pliers or fuel line disconnect tools, you can safely detach the connector without causing damage to the hose or the booster.

Once the connector is free, you can now fully disconnect the brake booster vacuum hose. Take your time with this step, as any sharp movements could lead to spillage or damage to nearby components. With the hose disconnected, you can proceed with servicing or replacing the brake booster as required.

Remember to work carefully and refer to a qualified mechanic if you are unsure about any aspect of the process. Working on brake systems can be complex, and it is always better to be safe and seek professional advice if needed.

Undo the fuel line clamps and hoses

To undo the fuel line clamps and hoses on a 2005 WRX, you will need to gather the right tools and follow a careful process to ensure you don't damage any parts.

First, make sure you have the necessary tools on hand. You will likely need a variety of sockets and ratchets, pliers of different lengths, and possibly fuel line disconnect tools or hose removal pliers. These tools will help you reach the various clamps and hoses and make the process easier.

Next, locate the fuel lines and clamps. The fuel lines on a WRX can be found running from the engine to the manifold. There will be a feed line, a return line, and an evap line on the driver's side. The clamps are what secure these fuel lines in place.

Now, it's time to start undoing the clamps and hoses. One method is to use a pair of side cutters. Grab one side of the clamp with the cutters and twist outward to uncrimp it. Do the same on the other side, and it should be loose enough to slide around. Be very careful not to damage the fuel lines themselves. Alternatively, you can use vice grips or expanding circlip pliers to clamp onto the tab and spin, breaking the clamp in a twist. This method may leave a sharp, ragged end, so caution is advised.

If you're looking for a more straightforward approach and have the necessary tools, consider using a fuel line disconnect tool or hose removal pliers. These tools are designed to simplify the process of removing fuel lines and can save you time and effort. Simply follow the instructions for the specific tool you are using, being careful not to damage any surrounding components.

Remember to take your time and work carefully. Fuel lines and hoses are crucial components of your vehicle, and any damage or improper installation can lead to leaks and other issues. Always refer to reliable sources or seek professional assistance if you're unsure about any steps in the process.

Use a fuel line tool to unclip them from the hardlines

Using a fuel line tool is the easiest way to unclip the fuel lines from the hardlines of your 05 WRX. This is a safer method than attempting to use a screwdriver and pliers, which could result in fuel leakage.

You can purchase a fuel line disconnect tool set online from sites such as Amazon, eBay, or Summit. These are available in metal or plastic, and in a variety of materials including plastic, aluminium, and steel. Metal tools are generally recommended over plastic as they are stronger and more durable. You can also buy these tools from auto parts stores, and they are very affordable.

If you are unable to get a hold of a fuel line tool, there are some DIY methods you can try. One method involves using a small metal clamp. You can cut off the screw portion of the clamp, wrap it around the fuel line, and push it into the connector with your fingers and a screwdriver. Another method is to cut a white BiC pen sleeve into a 1/2-3/4" long cylinder, slice it open, slip it over the line, and use pliers to press it into the fitting.

However, it is important to note that these DIY methods may not be as effective as using a proper fuel line tool and could potentially damage your car.
