So far so good, I removed the fan housing, the alternator and then had full access to the oil cooler. Worked very well, I was into the cooler in just over an hour, If I knew what I was doing I think it would have been a shorter amount of time. Now the seals are installed, and I replaced the motor mount while I was in there and I have re-assembled everything to putting the pulley back on the alternator, damn key, what a pain in the butt. After that the tin and I am done. So it can be done inside the van quite easily. I did not have to remove the heater boxes either.
