I'm replacing the EGR valve on my truck. Do I have to replace the tube as well? Or can I just clean the inside of it? If so, what would be a good cleaning solution?

Thanks

Hello,

You can clean the EGR tube. Depending on the amount of buildup you can use a stiff bristle tube brush and any cleaning solvent to do that task. Most parts cleaners will work just fine. Typically, you can get those from your local parts store they come in a spray bottle.

As long you can get the solvent inside the tube and use the brush to clean it out it will work.

Here is a helpful video on how to test the EGR valve:

Please let me know if you have any questions.
Thank you.

Great advice, SQ Appreciate it. Another question. In order for me to disconnect the tube from the exhaust, do I have to take the manifold out? Hope not.
Thanks again.

Removing the EGR tube from the exhaust does not require removing the manifold. That nut usually gets rusted so it could be a little challenging to get out but using some penetrating spray should help loosen it up.

I have attached the torque specifications below.

Outstanding. Another one, if you don't mind. How do you check the EGR solenoid?
Thanks a million, SQM.

First you want to make sure that you have power to the solenoid. You can use a multimeter to check for power at the harness. You should have 12V with the key to the on position.

As for testing the solenoid, you can apply 12V power to the pins of the solenoid. If it is good, it will make a clicking sound. Bad solenoid typically does not make any sound.
