Do I have to

[star4772]

drain the antifreeze to replace the freeze plugs or just do a quick out and in with the new then refill?? What's the best way to do it??

This is up to you. That said, you be the judge...If it is new fresh antifreeze, in and out. If it is old, drain flush, clean then install. I have seen old auto mechanics drive an old leaky plug into the block of a car with the new plug. No evidence. I do not condone this, just said I have seen it done. I have not had to do this particular repair. some one else will chime in with their wisdom and knowledge any time.

It looks to be fresh antifreeze I just did the shim thing till I get new ones that I ordered.

 

Thanks for input.

I've never done one, but I expect very little will run out (assuming the cooling system is full). Just make sure it's cold when you do it, it'll spray you with scalding coolant if it's hot.
