How to Change the Catalytic Converter on a Toyota RAV4

Hi! good morning, now we will made an article about How to Change the Catalytic Converter on a Toyota RAV4

The Toyota RAV4 has two catalytic converters. The front one bolts directly to the manifold at the front of the exhaust system and the second one bolts directly to it. In most cases, the failing converter will be the rear converter. Continue reading and learn how to change the catalytic converter on a toyota rav4.

Converters fail after a while of stalling, internal breakdowns (which are the result of stalling and overheating), and have inlet and outlet pipes that crack or have exhaust leaks. Having to replace them requires a bit of experience or the right directions.

Steps to change the front catalytic converter on a Toyota RAV4

The steps you must take to replace a front catalytic converter on a Toyota RAV4 are as follows:

1. Put the Toyota RAV4 on a car lift and raise it to the end

Place all the tools you need in the tool cart and rotate it close to you where it won’t get in the way of the action at work, but where you can easily access the tools.

To remove the five nuts that go into the manifold, attach the ratchet with a long extension, the swivel and a socket. In some cases, if the nuts are damaged, it may be necessary to replace the socket with a nut extractor.

2. Put on safety glasses and light the torch

Heat the nuts with the torch, being careful not to heat the nuts as well. It’s a tight area you’ll need to know how to handle a torch and adjust the flame level so it’s small enough to get the job done but hot enough to be successful.

When the flame is cherry red, turn off the torch and remove it with the ratchet, extension, swivel, and socket/nut extractor. Continue this procedure for the other four nuts.

3. Cut the bolts

Light the torch and cut the two or three studs (some of the rear converters have one three stud entry and others have two) out of the rear flange. Cut them on the side of the front converter so there is no damage to the rear converter.

When the bolts are torch cut flush with the flange, turn off the torch, put on your safety gloves, and tap the rest of the bolt out of the flange with a punch and hammer. Be ready to get out of the cut path or grab the front converter as it will drop as soon as I get free.

4. Let the system cool down

Install the front converter top with a new gasket on the manifold by threading some new nuts by hand. Tighten them one at a time with the air gun, extension (either short or long), ball joint, and socket until tight.

5. Place the gasket

Insert the gasket at the back of the front converter flange connection and secure it with the hardware (screws, nuts, washers). Gun-tighten the small extension (if necessary), turn and hold the lug nuts in place with a hand wrench. Remove the cart and tools and any debris on the floor, lower the RAV4 and start it up to check for possible exhaust leaks.

Well with these rigorous steps you will be able to change the front catalytic converter of a Toyota RAV4, it just is not an action for beginners. Be careful when doing this procedure.
