126 chassis heater core job
 

Hi I have a 1987 420 sel. I have coolant leaking inside the car from under the dash. How hard is it to replace the heater core? Do I remove the dash? How many hours?The shop manual dosent show anything about it.Help!!

I just mine on a 1989 190e and it took a little over 6 hours. I did have to take the dash out which was alot easier than I expected but very time consuming. You should try and do it soon becuase mine had a very minor leak and then one day it blew up on my leg in traffic. (Definatley not the safest setup I have seen) Good luck.
