Personally I wouldn't put any sealers in since you are fixing the leaking freeze plugs anyways. If you have to use some I would only useThe stuff from Barrs Leak. Not the brown liquid with the large pellets but the small plastic tube with a fine silver powder.

You need a quick disconnect tool for it. I got a set at AutoZone for like 19.99 with several different sizes. It was either 3/8 or 5/16" if I remember correctly.
Good to hear.

There's a difference between coolant and corrosion protection. The rad can be full to the top with coolant but corrosion protection in the coolant can be zero. The corrosion protection is what keeps holes from forming which in turn keeps coolant from leaking out.
Any brands that do their job for corrosion. Should I do this to the 07 charger too?

It looks like that kit is missing some. There should be at least 5 same-size brass ones, and some other assorted ones that I think are for the cylinder head and behind the engine. I wouldn't worry about those unless they are in bad shape and leaking. I just replaced the 5 that were accessible under the manifolds. Since you're primarily concerned with the one that's leaking, I'm sure you'd be fine just using those 4 brass ones to get the ones that you can.
I used a pry bar and a hammer to actually knock the existing plugs into the engine block, and then needle nose pliers to extract them.
It's pretty easy. 15mm for the belt--loose the idler pulley center bolt a bit, and then there's an adjuster bolt above it to loosen it. For power steering, IIRC there were some 13mm bolts and possibly a 15? There's one hiding behind that bolts it to the engine block. Remove your E-fan so that you can get your socket in the holes in the power steering pulley once you remove the belt.

How the heck does the belt and power steering come off. I'm losing my mind

Yeah I did. What a pita this project was. I want to thank you and everyone here at cherokee forums for all your help with my 98 jeep cherokee 4.0 freeze plugs. I hope the future cherokee owners take note and sign up here. I don't know what I'd do without the help I'd probably lose my mind. Thank you 100%
