my 03 2500 4x4 has a leak from the cooler that is located between the ac unit and the radiator. I could put an aftermarket cooler in it's place but I choose for now to replace the factory unit. problem is i can't find the factory cooler. The dealer wants to take it apart to tell me which one it is, no thanks. The truck is an 03 the build date according to the vin states it was built in December of 02, it is a 47re trans. does anyone know where to find a factory cooler? the cooler has 2 hard lines that come off the end turn down then turn under the bottom of the trans and go to rubber then back to hard line to the cooler on the back of the block. thanks for any help

 

looked around and found that this cooler tends to leak after about 100,000 can some one recommend a good after market cooler?
