EGR Valve Cleaning - 2001 Isuzu Rodeo
This video illustrates the method I used to remove, clean, and replace the
EGR valve on my 2001 Isuzu Rodeo. I was having problems with the check
engine light coming on, and each time the code was related to insufficient
flow from the EGR valve. Once I cleaned the valve, the check engine light
went off within the first half hour of driving afterward and stayed off for
a couple of months. It eventually came back on, so I decided to repeat the
cleaning process, except that time I also cleaned the EGR tube that feeds
into the intake. That solved the problem, and the check engine light has
not come on since (about 6 months to date). This process can be seen here:
I am obviously not a professional mechanic. I am just someone that likes
to try to take on small repairs myself, and I have been greatly aided by
other helpful videos on YouTube. My goal in posting these videos is to try
to return the favor and help someone that may have encountered one of the
same problems that I have. I'm sure there are better, more efficient ways
to do things, and I am certainly open to constructive criticism. However,
I hope that in some way my videos will be helpful.
Thank you for watching!
