I just bought this 2016 flex 3.5NA car for my wife. It just rolled 100k and I wanted to stay on the PM side of things. I know the water pump and timing chains are issues with these engines. I was contemplating doing it myself. I am mechanically inclined and feel confident doing the job. I’m asking anything important I should know. The OEM a timing set is on national back order so I’m looking at the Melling Professional set, then OEM water pump unless someone suggests a solid alternative. I’m not sure what I need for seals and gaskets. I understand the crank bolt should be replaced as well. What about antifreeze? I’m not sure what’s in it currently. What should go back in it?
And of course I’d like to hear thoughts on this job. The car is low mileage, the timing set isn’t making any noise but I figured if I’m in there why not. Or should I wait til the pump starts seeping which I know it can fail internally as well which would be catastrophic.
Also this will be posted over on GJ forum if anyone sees it doubly posted, I like an array of feedback.
