Okay, so it only took 3 hours to remove the heater core... but it took 7 to put it back together! All is good with new core, thermostat, housing and Prestone antifreeze! This thing will roast you right out of the cab now!
New core at top. Old core at bottom
My advice: ONLY buy the Motorcraft unit. The TYC was junk and with all the time and effort that it takes to get to it, use ONLY quality parts. The Motorcraft unit was only $20 more than the TYC.
Relocated EATC aspirator connection
I tested the EATC aspirator and it now functions as it is supposed to. I think that now, the EATC will maintain the proper temperature set point!
Out of all the various repairs I have done, the heater core in my '98 Ranger was easily the worst ever. Had to tear half the dash apart, what a pain in the ass. After all that, no way was I putting a bargain part in there!
