W201 Heater Core R and R
My 87 190D 2.5 NA has a leaky heater core after I replaced PO's Prestone with Zerex. I am gonna replace it, but I need to know what else I should replace (other than Vaccum Pots) while I have the dash apart. BTW Anyone does this lately? Any other tips would be great! Thanks! Clip

Many times the W201 chassis has coolant leaks from the heater valve that appear to come from the heater core.
Heater core job is about a complete days job on that car.. ALWAYS replace the feedback potientiometer & the vacuum element for the blend air door..top of heater case.. feedback pot will require adjustment. Also the fresh air vacuum element at the bottom of the box should be replaced. DOUBT if the anti-freeze change has any effect on leakage..
