steam coming from vents and anti-freeze on floor tell me I need a core...anyone replace the core on 1986 e-150 before?...I have a compuer box in the way...how do I get to it?....how pricy is replacement?...thanks
After you disconnect the battery, drain the radiator a little to get the level below the core. Remove the hoses from the core. On the inside, you should find 5 mounting screws around the box. Remove them.
Then remove the assembly. Remove the case seal from the face of the case & remove the retainer. Slide the core & seal from the case.
That is all there is to it!!
Now reverse the procedure. Leave the highest hose loose as you refill the radiator, to bleed the system.
You should be good as new!!!!!!
