    Default Sea Foam in Vaccuum Lines

    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.

    2COR517, when you pour the Seafoam down the throttle body how much do you put in? Do you keep the engine revved up some so it won't die? Do you have to change plugs soon after? All these years I've never heard of Seafoam, seems like it's overtaking the WORLD now!

    It is the 2004 tahoe with the 5.3 Vortec engine. I have no pic's of it. Anyone with one please chime in. I am going to take a look at the single hose. I do believe it is the right one.

    doesnt the tahoe have hydraboost? if it does then boost is multiplied by the use of the power steering pump not vacuum and the master cylinder should sit on this fixture that has i think two steel lines running out of it and into yoru p.s system
