I just thought of buying the factory stuff to do it how hard is it to do ???

 

Not hard or needed can go 200k easy. But if you want to drain it and put in a good 5 year coolant any make will work!

 

wouldnt hurt i work at dodge dealer so been usin 5 year coolant and never had problem benefit it was free.dropped the coolant out of rad once a year in fathers 05.overkill but wat tha hell it was free.rad takes approx 3-4 gallons.
