Replacing '14 engine. Never done it before
5.0 v8 2014.
coolant started boiling and smoking, had oil in it. Oil had coolant in it.
Quotes for repairs were- head gaskets for $2k, rebuild for $6k and full replace for $10k-$16k.
going to give replacing it myself a shot. have worked on cars, but nothing major like this.
Got the truck less than a mknth ago from a dealership that won't help me (no warranty, lesson learned). Im a landscaper so i cant wait for the repairs and I certainly cannot afford them.
Open to any advice!!!!!!!!

Welcome to the forum. I’ve replaced engines on several vehicles but not in an F150. So I don’t have any insider advice to give you. But any time I plan to do something I haven’t done before I always search the interwebs for any videos that might be out there.
I’m putting my 13 back in right now. I left AC system in the truck just scooted the whole system forward. Had to unbolt but not remove battery tray to get enough clearance for that. You just have to detach a few wires in the passenger side and the whole wiring harness comes out nicely with the motor. There are a few wires for the alternator and starter connected to studs on the oil pan, so don’t forget those. In general, pull rad first and work front to back and you’ll have plenty of room. Feel free to follow up either way any specific questions. You’ve got a couple days left before it’s all together if you want pictures of anything
Was thinking about subscribing to ALLDATA DIY because I cant find an exact rundown of my exact truck, and am not sure what small details to look out for

Two ways to get better clearance for removal without full cab body lift if you are doing it from the ground (at least for the 3.5L), after setting the front of the frame on jack stands and removing front wheels: 1) disconnect the big front cab-to-frame bolts (likely need new ones after removal!) and the four (two each side) cab-to-frame nuts at the doors (leave the one big
Highly highly recommend downloading the 2011-2014_f-150_service_repair_workshop_manual ... (begin at section 303-01C for the 5.0L - but lots of in-vehicle engine repairs and engine installation before you get to engine 'removal' section on page 2,490!) the step-by-step instructions with
Good luck! Let us know how it goes!

Work carefully and don't put body parts in pinch points or under suspended loads.
If you get tired, aggravated, frustrated, walk away until you can figure things out.
Don't be afraid to ask for help, either here or a friend, when you need to.
