Ford Excursion heating problem
Hi all,
Truck is a 2004 6.8L V10
I am new to working on my truck myself besides a basic oil change. I have a seasoned friend helping me once I get all the parts to walk me through the ropes on installation.
I ran into a problem with a check engine light and a overheating issue after pulling a 21ft snowmobile trailer (empty weight of about 3k and was empty at the time) . We have ran a scanner and found that to start I will need an new radiator with: water pump, thermostat (code: P1299) . I will also be changing the spark plugs and coils as well (codes: P0300, P0306, P0307). We also got a code P0316 which says there is a misfire with the fuel injector at the first 1k revolution. We believe that just changing the Spark plugs and coils will solve this problem.
This is the part list I'm looking at getting for starters:
Spark plugs and Coils
Water pump
Thermostat Site says it will work with my excursion
Radiator With the sites recommended coolant mix.
Any advice is appreciated to get it running again,
Nicholas

The coils should only be either Motorcraft or Denso coils.
The spark plugs should only be Motorcraft or Autolite plugs.
If you use anything else, it may run but you'll have issues with misfires and/or the truck won't perform its best.
Dump 4 cans (Yes 4) of Berryman B12 in half a tank of fuel and drive it like you stole it.
I'd recommend getting the parts off RockAuto as they will have the Motorcraft parts. If you buy off Amazon or EBay, you may end up with a knockoff part.
Thermostat: RT-1195
Coils: Denso 673-6000
Plugs; Autolite APP103 or Autolite XP103 or Motorcraft SP479X
Fan Clutch: YB3082
Water pump: Gates 42079 or Melling MWP510
Coolant: Ford Premium Gold aka Zerex G-05
This should take care of your cooling system issues.

honestly, only buy 1-2 coil packs (COP). They are either good...or bad. There is no grey area. And they aren't cheap, so don't fire the parts cannon unnecessarily.
Do a tune-up using only Ford Motorcraft parts as Tor mentioned. Ensure you change the boots/springs as well and liberally use dialectric grease on the boots where they seal to the head. this is a major leakpoint for water and future issues due to shorting. dialectric grease seals it up.
for the coil packs, if you suspect a miss/bad COP; run a live monitor. Most code readers can do this. Scanguage, Torque, etc. You need to watch cylinder data and monitor misfires live. This is pretty much the only way to see if a COP is bad beside swap/watch. Replace the COP as needed AFTER verifying it's actually bad. Verify the misfire goes away. Unfortunately the OBD2 system isn't fully compliant on the X. It's a dumbed down version from what most modern vehicles have due to their classification as Medium Duty vehicles. Only CA models have the full OBD2 ability enabled.
