I know.. yet another 5.0/4R70W swap. I've read a good bit of the threads and gleaned enough information to make me comfortable giving it a shot.
This will be me first swap of any motor/trans. I originally intended this for be a 'help me' thread, but after seeing many of the same questions, I figured I'd turn this into more of a 5.0/4R70W for newbies thread. Ie, hopefully I can generate a good part list and provide pictures as I go through it, to hopefully help others also take the leap..
Here is what I am working with:
What I should keep?
What should I strip before I scrap it? I'm going to post it on some of the local for sale sites and maybe toss some of the light/valuable stuff up on ebay.
What are my next steps:
What I need to purchase:
Parts to replace:
I'm planning for this to be a neighborhood cruiser, family ice cream getter.. something I can enjoy driving, and possibly my wife. the original 302 was in good running condition but I would really like EFI on a budget. The Mountaineer was reasonable so I feel i'm off to a good start.
Sorry for all of the open ended questions/ramble. I've tried to compile as much data from all of the threads.. lots of good lessons learned.. exactly why i love this forum. I'm hoping some of the veteran 5.0 swappers can chime in with what they might have done differently, or what a newbie should watch out for?

Here is what I am working with:
- 1974 EB w/ stock 302.. Came with a Flaming River column, Painless Harness, 2" body lift, etc, so I think i already have parts of what i need. I plan to pull the body to strip the frame this summer and install the new powertrain while the body is off.
- 2001 Mercury Mountaineer. 5.0L, with AWD (I believe 4R70W) trans
- 122k miles, 2 owners, was salvaged by insurance due to it being backed into something and damaged rear hatch
- I have started the Mountaineer up and driven it around the block. No white smoke, shifts smooth, what i remember these vehicles driving like
What I should keep?
- Everything physically attached to the engine & trans
- Air intake plumbing, with MAF sensor.
- OBD2 port and inertia switch (with pigtail) from inside the cab.
- Engine harness, transmission harness, and firewall harness
- Throttle cable & pedal
- Fuel line plumbing (likely need new hose since 18yrs old)
- Fuel pump assembly.
- Power steering pressure hose.
- Cruise control module.
- Fuel pump flange from gas tank
What should I strip before I scrap it? I'm going to post it on some of the local for sale sites and maybe toss some of the light/valuable stuff up on ebay.
What are my next steps:
- Pull engine & trans, start cleaning/blasting
- Replace all fluids, plugs, wires, timing chain
- Have EFIGuy reprogram ECU and possible rework harness (need to watch his video again to determine if I can tackle it.
What I need to purchase:
- AA adapter for mating 4r70W to Dana D20. Most popular option is the ZF adapter: Advance Adapters Transfer Case Adapters 50-4303 cut .8" to 1.5" off the tail shaft to make it
- You will need Timken 471950 to keep the ATF from flowing out and filling the D20
- 23gal fuel tank for EFI. Possibly made to fit for Mountaineer Fuel in-tank fuel pump. I ended up using an older NWMP w/ a Tanks Inc PA-2 pump assembly
- Headers for the GT40P heads (Bronco Hut)
- 4R70W crossmember (BCBroncos) - note: depending on the AA adapter, dictates which crossmember you need to use.
- Upgraded gauge w/ added Voltmeter & possibly check engine light?
- Spare ECU to have EFIGuy program (Ebay, PickNPull)
- Radiator. Explorer 5.0 doesn't work, you can use a stock EB radiator, but need new hoses:
- Lower Radiator Hose: 2002 7.3 diesel F350 lower #22690 work with a little trimming
- Lower Radiator Hose: You cut the factory lower hose into 3 pieces. In a nutshell, use either end and throw away the middle.
- Upper Radiator Hose: 1998 4.6 Crown Victoria upper hose #22392
- Upper Radiator Hose: Continental factory upper hose from Summit racing (CEL-60710). The other hoses from Gates, Dayco, and whoever else's are different. You take the hose, put it on backwards, and then you have to put a splice in it so you can rotate it. There is trimming done on both ends to the rad and thermostat housing.
- Fan shroud? WildHorses Aluminum Shroud (looks great, $$)
- Air intake: modify factory box, or use Mass Air Flow Sensor Intake Adapter Plate For 94-95 Mustang 2dr 5.0 V8 (ebay)
- Need shift adapter linkage for aftermarket column: Lokar ACA-1808 Adjustable Column Shift Linkage Kit
- Oil Filter Adapter to remove oil cooler: f1az.6890.b
- ECM box (pull from 2003 escape, pickNpull)
- Twin Sticks for transfer case. Note: you will have to modify the Advance Adapter arm that the twin sticks mount to. You will want the middle clocking position, not the 3rd that this arm is set up for.
- Power Steering adapter fitting:https://leepowersteering.com/produc...-with-seat-ford-pumps-racks-pinions-16mm-to-6
- Heater control valve and hoses. Murray Heater control valve #74628. This valve flows opposite to the Bronco valve, but correct for the Explorer flow. Gates hose #19070 is cut to fit and you use this one hose to do heater
- Napa #NBH36079 - 60mm pulley (if you have front crossmember clearance issues)
- Gates Serp belt #K060825 for AC delete
Parts to replace:
- Motorcraft KM-1935 water pump bypass line
- Motorcraft KH581 - water pump to heater line
- Melling M68 Oil Pump
- Motorcraft RT1139 Thermostat
- Motorcraft RG605 Engine Coolant Thermostat Housing Gasket
- Motorcraft Wr-6034 - plug wire set (maybe too long?)
- Motorcraft dg-530 Ignition coil (2)
- Motorcraft SW1547B Oil Pressure Switch
- Motorcraft SW232 Water Temp Sender
- Motorcraft E7TZ-6268-A Timing Chain - note this varies by year. it took me 2x to find the correct one
- Motorcraft PW-343 Water Pump
