Just learned the heater hose on 2007 - 2014 5.4's is a pricey item. There are 2 hose/plastic connectors above the top right hand side of the engine. One line has a plastic "T" while the other has a plastic 30 degree splitter. It's normally the plastic "T" that fails. The entire unit, both hoses and such runs $150+. It also requires a plumbing disconnector to remove if you follow factory rules. I did a work around with a 3/4" plastic "T" from isle 3 of the auto parts store for $5. The slip connectors can be removed with side cutters saving $50 for the special unit they suggest from FoMoCo. This is s common problem after 5 yrs and 100k. "Happy Trails...., To You..."
