Lower rad hose size
Im having trubles with the rad hose size. Im not looking for a part number but just the size. I tryed 1 3/4in and it was too small and 2in is to big. 2in is good for water pump but not rad. Im just using flex hose. I have 2in by 17 in long one wich fits but is to big. I had a 1 3/4 in by 16 1/2 long and it was to small. I have the origanl rad with the pointed up outlet.
