[diesel_mercedes] AC Compressor Part Number Delco R4 original

 

This is for W-123's with the 5 cylinder OM617 engine , prolly the same on the OM616 4 cylinder engines too :

Delco # 52390419


It's the new , Delphi item , it's been on my '84 300CD since I bought it and works fine , quiet and no leaks .


I'm about to remove it and replace with a SANDEN unit , I'll prolly use this good R4 compressor on my '84 3--TD as it needs working AC .


If you use this Delco / Delphi P/N , you should be able to find it new for about 1/2 price .


WARNING ~ _DO_NOT_EVER_ buy a ' rebuilt ' Delco R4 AC compressor ! .


NEW ONLY ! .


It comes dry and you'll need to add some PAG oil , the book should tell you how much to add .
