wolfe10 Report post Posted August 16, 2013 SteveCynthia, Welcome to the FMCA Forum. Your chassis maker (Freightliner or Powerglide most likely) choose the coolant and the cooling system. So, check with your chassis maker to find out what coolant you have (and whether it needs testing and use of SCA) and the recommended change interval. They can also tell you if a coolant filter is fit. Brett Share this post Link to post Share on other sites
