I've been reading and watching some YouTube vids on flushing the system. I see reference to newer vehicles that it does no good to flush them due to the condenser construction. I have a 1996 Ranger which is now 21yrs old, does anyone know if this applies to this vehicle? If so would this also apply to the evaporator? My compressor went bad and I'm sure the system has metal particles throughout the system.

Well if it can't be flushed then it will need to be replaced, so I would try to flush it.

The point of flushing is to remove all the oil from inside the components of the system, the oil is needed to lube the compressor and the oil coats the inside of the system and dirt/metal debris sticks to the oil, flushing fluid cleans off the oil and with it the debris

Good article here: http://www.teamec.be/cms_files/Flush...eaning(EN).pdf

The Orifice tube/filter usually protects evaporator from debris, this filter needs to be changed

Orifice tube should be between 9 and 10 in the diagram

 

Thanks Ron for the reply and links. I decided to buy a condenser. The compressor kit comes with a new orifice tube so yes that will be changed. The only two items I will flush now will be one hose and the evaporator everything else will be new.
