Need a NEW heater core for a 1998 Monaco Windsor Part number I have is E56407. I found one place at $276 surely there is another source for less than that---if not I'll just bite the bullet.
3 more hours and it is out. 5 total. Pretty straight forward but with little more than the Irv pictures it took me awhile because I didn't want to break or mess up anything. That sucker was stuck even after all the bolts were out....there are only 4 as the other 4, which I also removed, hold the metal piece on the back on. Now to order a new one.
