how Seafoam 2008 grand cherokee hemi

I been reading but not finding exactly where to put it. I should put 1/3 can in oil, gas and brake booster? Where is the brake booster at? Is it the tube that says brake booster that is behind the steering wheel?

Thanks for you time.

My vehicle: 2008 grand cherokee limited 5.7 4x4 113340 miles.

That's the vacuum line connecting/supplying your booster. It's says to put it in the 'brake booster' ? Or 'brake master cylinder' ?

It says to put it in a vacuum line, I read that the brake booster is the most popular?

Brake fluid is the ONLY thing you put in your master cylinder. Period!

Yes, the engine must be running.

On mine there is a small capped off port just behind the TB that I hook a short hose to and run it in through there. The idea is to make sure you feed all cylinders.

If you want it in all cylinders shouldn't you pit it through the intake?

the vacuum is ported into the intake so ^^^^^^^^^^^ you are correct. the brake booster is common and usually a rather large hose. thats why they recommend it.

No real reason to not just put it in the gas tank -it mixes and cleans in the mixture just fine in my experience.

Running it through the fuel alone will really only clean the fuel system. Running it through the intake will much more aggressively clean the intake ports, valves and combustion chambers to rid them of carbon buildup.

I've had good success getting cats to perform better with a couple good seafoam treatments as well.

Make sure you change the oil/filter within about 50 miles of putting it in the oil.

Usually day after Seafoam is what I do. You don't wanna run all the churned up dirty oil for too long.

What problem are you trying to solve?
If you want to clean the injectors and intake valves put a bottle of Techron in the tank.

I did it yesterday, everything went fine. I put it in the vacuum, oil, and gas. I also got the intake cleaner and used that to. It did clean the intake but it is still dirty. Thanks for all you help.
