DJHogdogger where are the fins? Is that gonna be right in front by the radiator? My truck is doing the same thing although it is not a diesel.
Yea

I don't know what they are called. They just look like fins to me. Thats girl talk for what ever those things are in front of the radiator. We always washed them out with water but a whole lot of junk came out when he used dawn soap. Maybe it was a coincidence but the a/c started working fine after he did that and its beens over a year now and still going.
