I have a 04 Avalanche and I am trying to use seafoam but the throttle body is the electronic one where i can not manually open it and the truck does not have a brake booster line that I can pour it through

Where else can I put it in intake?

 

Through the PCV valve line on the back of the drivers side valve cover.

 

If you put the key to on (dont start) and press the gas pedal, doesn't the TB open? Maybe not but I thought it would. Have somebody sit in the seat and hold the pedal or use a brick. I may be full of , someone correct me.

 

You can disconnect the brake booster line and pour it in through there and will clean your intake system. That is the way that I did mine.

 

I have heard various stories about sea foam on this forum....I would do some research on here before you dump it

 

The newer trucks dont have a standard brake booster with the vacuum line. It looks like it has a pump or something on it. I didnt believe it till i saw it either.

 

if your truck isn't started and you take off the intake tube you can push the throttle body open with you hand. i wouldn't do it if it was started though
