Rv antifreeze

[sea sick again]

Hello I dumped 4 gallons of rv antifreezs in my 5.8 thru my cobra out drive then drained the block and manifolds BUT then some one told me the inside of the motor would rust sooooooo I put the plugs back in and dumped eight gallons in thru the thermostste hose and it still seemed thursty were did it go? Am I good for the winter?

Re: Rv antifreeze

How are you putting the antifreeze in is the big question.

Drain the block,manifolds,risers, and drive.
To put antifreeze in or not has been debated over and over.


This is my way correct or not drain all water start at the top risers,manifolds,block, and large hose to eng water pump.

get a five gallon bucket,old bilge pump,set of muffs.
Put muffs on the drive fire up the pump start eng till anti freeze comes out of block then close those drains. Repet this for manis and risers.

This is a little over the top but it works for me.
Good Luck
