    Did this to my truck and the wife's Ford Fusion last weekend what a difference. I put some in the Vacuum lines and in the tanks on both cars and it has made a significant difference. Her car was starting to start hard and it has completely cleared up. I also noticed today at O'riely's auto parts today that they had buy 2 get one free. Not a bad deal.

    I have an 04 Tahoe with the 5.3 Vortec engine. How do you Seafoam this? I use the brake booster hose on my other vehicles but cannot find it on this vehicle.

    I pull the air snorkel off and dump it right down the throttle body.

    What's the purpose of this Seafoam stuff? What does it do?

    it's suppose to clean up your fuel system & any carbon build. here's a link to the actual site:

    after hearing peoples testimonies about seafoam on youtube and on forums that i'm on, i figured i'd give it a try. i was very much impressed with the results. my cherokee idle smoother and runs like a champ even more.

    Thanks! I'll check it out. Sounds like something the Tahoe would like.

    For the tahoe, there is a big black container that has your brake fluid in it with the tubing going down, there will be ONE rubber hose going to the back of your intake manifold, disconnect it and put a funnel on the end, start the engine, and slowly pour the seafoam in. It may stall, but thats fine start it back up and keep pouring slowly.
