Heres a little trick for you guys with older trucks...the little 90 degree rubber nipple that attaches vacuum to the heater control valve gets old and worn out, it does not fit as snug as it used to. Snip off 1/8" of the rubber.....then re apply. It fits snug again
Before putting the upper plenum on (UIM) on these 4.0 you have to install the AC line, it routes around the back of the engine
the AC line and compressor always get new O rings
The AC high pressure switch wires from the 3.0 harness do not reach the 4.0 AC line, so I stripped back the factory conduit and made enough length without cutting anything
scored a fender badge at the JY
EGR tube was cleaned and installed a new EGR gasket/O ring
Time to install the UIM, new O rings are needed. Use a pick to pull the old dry ones out, clean the areas with Q tips and apply new O rings with a slight coating of vaseline
Intake is on
time for plug wires, I LOVE packard wires, sold under many diff names
Time to clean the MAS, holy crud. This one was really nasty....it came from the 98 ranger that had an engine full of water.... I use carb cleaner and spray the crap out of the sensor wires. I had to use a Q tip to carefully remove some dirt this time. Normally I try not to touch the sensor wires at all
Coming together!!
We ditched the single core 3.0 radiator in favor of this 5.0 dual core from an exploder.
Ready for a battery and fluids!
Fingers crossed!!
