Like all other vehicle parts, your water pipe gets worn out over time. Even if it's made from the toughest materials that have good resistance from corrosion, replacing it after a certain period of time is inevitable. Here are the steps on how to change your water pipe.
Difficulty level: Moderate
Tools that you'll need:
- Mallet or hammer
- Penetrating oil
- Nut drivers
- Throttle body cleaner
- Thin scraper
Step 1: Open the hood of your car. Take off the intake tube by loosening the screws and pulling off the hose.
Step 2: Unbolt the throttle body, and remove it.
Step 3: Disconnect the hose holding the intake manifold and the idle control valve together. Simply twist it for it to come off.
Step 4: Undo the nuts attaching the upper intake manifold to the lower manifold. Carefully lift up the manifold to remove it.
Step 5: Remove the thermostat housing. You may also remove the oil filter housing if you want to have better access to the pipe, but it's really not necessary.
Step 6: Disconnect the two electric connections on the side of a small black plastic box. Remove the nuts holding this box.
Step 7: Unscrew the water pipe bolts. The back-end bolt can be found behind the hose connection.
Step 8: Clean the water pipe, and scrape off the old gasket.
Step 9: Remove the water pipe. Use the bracket and leverage to pry it off.
Step 10: Install the new water pipe by centering the inlet onto the block. Make sure that the pipe is not lopsided. Once you have it on right, push the pipe in as hard as you can. You may also gently tap it in using a mallet until you hear a plunk sound.
Tip and warning
- In removing the intake manifold, make sure that you are lifting it up evenly on all sides or else it might get stuck on some bolts.
- Be careful of the bottom part of the intake. It's really sharp.
