Seafoam 2004 Pontiac Grand Prix GTP (supercharged)
Odometer reading at the time of this procedure was just over 88k. On GM's 3800 s/c V6 you DO NOT suck Seafoam through the brake Boost vac hose. SF may damage the Teflon coated s/c rotors. Instead, discount the vacuum line directly beneath he s/c snout. Once you remove the tube/line you'll see a metal fitting going into the engine. Just attach another tube to it so that you can have the running engine drink the SF.
How To Seafoam Your Vehicle
2 Can of Seafoam & 1 Can of Deep Creep - 1 can goes into your fuel tank and half of the other one goes into your oil and the other half goes through the brake Booster line. The Deep Creep is sprayed through the throttle body. Let the vehicle sit 15-20 mins. and start up and watch the smoke show. If you have no smoke your vehicle didn't have any carbon build up to clean off.
