five Report post Posted March 10, 2020 One more comment on a coolant filter. I called Freightliner prior to having my coolant changed. They said no coolant filter, they don't use them. Much to my surprise, when we were draining the coolant, we found a coolant filter that was virtually totally plugged with crud, sludge and similar 'stuff.' So what happened was that DD put the filter on at the factory and Freightliner did not know it. Share this post Link to post Share on other sites
manholt Report post Posted March 10, 2020 FIVE, be happy that DD & Factory did. One reason I don't like or want Freightliner...they experiment on your dime! All that crud would have been going into the DD500! Replacement cost? Share this post Link to post Share on other sites
jleamont Report post Posted March 10, 2020 Funny, we had a bunch of DD13's at work that didn't come with a filter, recalled them back, installed filter, put it right on the frame next to the passenger side tire (no body said they were smart) 3 years later, recalled them again and pulled them off, after we had several leak from getting punched with road debris. I asked why? we made a mistake....which time?? no response. Share this post Link to post Share on other sites
