What to do after Seafoam?
Thats it.
If you want to do the top end cleaning with the Sea Foam you can read the sticky about it. But you will need two full cans to do it right, 1/3 of a can is nowhere near enough for that process.
Also, if you want better engine protection, throw the K&N air filter in the garbage and get a real filter, AC Delco paper filter. And you also won't have that K&N grease crap getting your MAF dirty and making your engine run gradually worse and worse.

Buy a bottle of some type of radiator flush.
Take your t-stat out and bolt the housing back up.
Drain just the radiator and add the bottle of flush and fill it back up with just water.
Let the engine run for about 30 minutes or drive around like that for a couple days if you can.
Then, with the engine cold, take the pet-**** drain plug all the way out. Not just open it up, take it all the way off so its a larger drain for the old coolant to get out.
Open the radiator fill cap and stick a hose in there. Start the engine and let it run like that making sure the radiator is always full while the coolant is circulating and draining out. Do this until the water runs out clear, maybe 15 minutes.
Put the drain plug back in, put the t-stat back in and fill it up with Dexcool/water. Wait for a couple cycles of the t-stat opening and closing and keep topping it off so you know the system is completely full of coolant.
Done.
