marklmiller20 Report post Posted October 18, 2023 Can I use air to blow out water lines to winterize my 2018 RT Adventurous or must I use antifreeze fluid (which leaves aftertaste in the spring). Share this post Link to post Share on other sites
aztec7fan Report post Posted October 18, 2023 You will hear advice on both sides of the compressed air/antifreeze topic. I'm on the antifreeze side, since i sleep better at night when i see that pink stuff come out of each faucet. I never have noticed an aftertaste once i flush the system in the spring.
