Replacing Oil Pan On A 2002 Mazda Protege: Step-By-Step Guide

Changing the oil pan on a 2002 Mazda Protege is a complex and dirty job. The oil pan is a durable part that can last the lifetime of the car, but a sharp impact with a hard surface at high speed can cause it to start leaking. To change the oil pan, the vehicle must be raised and supported on jack stands, and the oil drained. The oil pan is then removed and replaced with a new one, before adding new oil and a filter. The engine is then started and checked for leaks, and the vehicle is lowered.

Jack up the car and place jack stands

Jacking up your car is a crucial step in changing the oil pan of your 2002 Mazda Protege. Here is a detailed, step-by-step guide to help you through the process:

Firstly, locate the jack placement point. For the Mazda Protege, the jack should be placed under the subframe, behind the front passenger wheel. Ensure that you leave enough room for the jack stand to be placed between the jack and the front wheel. This will ensure stability and provide space for you to work comfortably.

Once you have identified the correct placement point, carefully position the jack and begin to raise your car. Raise the car to a height that allows you to comfortably work underneath it. Remember to never work under a car that is only supported by a jack. Always use jack stands to ensure safety and stability.

After raising the car to the desired height, it's time to put the jack stands in place. Place the jack stand between the jack and the front wheel. This will provide a stable and secure support system for your car. Once the jack stand is in position, you can slowly lower the car until the jack stand fully supports the car's weight, and the jack no longer has any load on it. At this point, you can remove the jack. Remember to consult your jack's user manual if you are unsure about how to lower it.

With the car securely supported on the jack stands, you can now proceed with the next steps of changing the oil pan. Remember to exercise caution and ensure that the car is stable and secure throughout the entire process.

Now that your car is securely jacked up and supported on jack stands, you can proceed with draining the oil and removing the oil pan. Remember to place an oil drain pan underneath the oil drain plug to catch the oil as it streams out. Always wear protective gloves and eyewear when working with motor oil, and keep rags or towels nearby to wipe up any spills.

Drain the oil

To drain the oil from your 2002 Mazda Protege, first place a jack under the subframe behind the front passenger wheel. Ensure you leave enough room for the jack stand to be placed between the jack and the front wheel. Use the jack to raise the car so that you can comfortably work under it. Place the jack stand between the jack and the front wheel, then slowly lower the car until the jack stand supports the car.

Now you can begin to drain the oil. Locate the 19mm hex oil drain plug on the passenger side of the car, facing towards the rear. Place an oil drain pan underneath the oil drain plug, ensuring it is positioned to catch the oil as it streams out. Put on protective gloves and eyewear, and keep rags or towels nearby to wipe up any spills.

Use a 19mm box end wrench to turn the oil drain plug counter-clockwise until you can turn it by hand. Finish removing the plug with your hand. The oil will begin streaming out of the oil pan. Watch for any shiny specks in the oil, as these could be metal flakes and may indicate a serious problem with your engine. Once the oil has slowed to a drip, wipe the area around the drain hole with a clean rag or towel.

Place the oil drain plug back over the hole and turn it clockwise by hand as far as possible. Finish tightening the plug with the 19mm box end wrench until it is snug, but be careful not to over-tighten as you may strip the threads or crack the oil pan.

Remove the oil pan

To remove the oil pan from a 2002 Mazda Protege, follow these steps:

Firstly, ensure the car is raised and supported on jack stands. It is important that the car is secure and will not slip or fall, as this could cause serious injury or death. Place the jack under the subframe behind the front passenger wheel, leaving enough room for the jack stand. Use the jack to raise the car, then place the jack stand between the jack and front wheel. Now, slowly lower the car until the jack stand supports the weight of the car.

Next, drain the oil. Locate the oil drain plug, which is on the passenger side of the car, facing the rear. Place an oil drain pan underneath the plug to catch the oil, then, wearing protective gloves and eyewear, use a 19mm box end wrench to turn the plug counter-clockwise. Once loose, finish removing the plug with your hand. Oil will begin streaming out. Once the oil has drained, wipe the area with a clean rag or towel.

Now, you can remove the oil pan. Remove the oil pan mounting bolts, then screw in an oil pan bolt in a weld nut hole to make a small gap between the oil pan upper block and the oil pan. Finally, remove the oil pan using a separator tool.

With the oil pan removed, you can now replace the gasket, clean the interface, and install a new oil pan.

Install the new oil pan

To install the new oil pan, first, make sure the oil pan is compatible with your Mazda Protege model. There are two types of oil pans used in the Mazda Protege, one with a main bearing support plate (MBSP) and one without.

If your oil pan has an MBSP, you will need to remove the transmission to access two hidden bolts. Apply liquid sealants to the MBSP and oil pan, ensuring a tight seal.

For both types of oil pans, follow these steps:

• Disconnect the negative battery cable.
• Drain the engine oil.
• Remove the front pipe.
• Remove the oil pan mounting bolts.
• Use a separator tool to create a small gap between the oil pan upper block and the oil pan, and remove the old oil pan.
• Install the new oil pan by following the removal steps in reverse. Ensure that the oil pan is not bent and that the bolt-up surface is clean.
• Start the engine and inspect for any oil leaks.

It is important to note that repairing or replacing an oil pan can be a complicated and dirty job, and there are specific recommended procedures in the shop manual for this vehicle. It is always recommended to consult a professional mechanic if you are unsure about any part of the process.

Check for leaks

After you've replaced the oil pan on your 2002 Mazda Protege, it's important to check for leaks. Here's a detailed, step-by-step guide on how to do this:

Firstly, make sure you've reconnected the negative battery cable and refilled the engine with the correct amount of fresh oil. Carefully remove the jack stands and lower the vehicle. Reconnect the negative battery cable and start your engine.

Now, it's time to check for leaks. Keep in mind that oil leaks can occur from many places in the engine, so you'll need to do some troubleshooting to determine the source of the leak. Start by locating the oil pan and examining it for any signs of oil dripping or pooling. Double-check that nothing above the pan, such as valve cover gaskets or the timing cover, is dripping down and making it appear that the pan is leaking.

If you don't spot any leaks from the oil pan, the next step is to check the oil level. Allow the engine to cool down for at least an hour, then re-check the oil level with the dipstick. If the oil level is more than half an inch above the top hole of the dipstick, you will need to drain some oil. If the oil level is below the bottom hole of the dipstick, you will need to add more oil.

If you suspect that the oil pan is leaking, there are a few additional steps you can take to confirm the source of the leak. Clean the entire oily area with brake parts cleaner and allow it to dry. Then, spray white foot powder or equivalent all over the suspected leak area. Start the engine and stay clear of moving and hot parts. The leak should become apparent rather quickly.

It's important to note that you should never get underneath a car unless it is safely and properly supported. Always use jack stands and safe jacking procedures when working under your vehicle. Additionally, always wear safety glasses and protective gloves when working with engine oil.
