2013-2016 Gen3's - Tutorial for Coolant Reservoir Overflow Hose Replacement - They can get BRITTLE!

224 Views 0 Replies 1 Participant Last post by  rahrena8690
Featuring a 2013 1.6L EcoBoost, this tutorial shows the following:
  • Removing the splash shield
  • Removing wipers and cowl
  • Removing engine cover
  • Removing air box and duct
  • Disconnecting old overflow hose
  • Installing new overflow hose

This hose is mostly a hard plastic line- at the attachment points near the reservoir and the radiator, my ~10 year old line was still strong and pliable, but near the engine where it wraps around to tie into the back, the heat exposure had made it super brittle. While going in to replace an existing coolant leak, this hose just cracked apart. The updated part shown for the 1.6L actually has more rubber tubing length near the engine to resolve this long term issue going forward. I believe the listed P/N's for the 2.0L and the 2.5L are still the original short length of rubber hose right where it sharply bends around to meet the engine fitting.

Note: The connection point at the back of the engine can be a pain- it's a pretty aggressive fitment of the hose stretched over the metal fitting on the block and after a decade, it may be tough to get off, especially facing away from you. Did my best to show what you're looking at and what I had to do to get mine off at least.

Good luck and hope this helps!
