Also, when was the last time that you changed your diff fluid ...and how many miles on your Supra?

It has roughly 65k on it and I have no idea when the last time it was changed. I purchased the car not too long ago but the dealership that I bought it from has no idea. Is there a diagram anywhere that can show me a location of the differential cooler? I'm probably in the next week or so I'll probably take it to Toyota for all the oil changes etc. I just don't want to walk in there blind and have them run me for a loop. I'm pretty mechanically inclined but I just need to know if this is totally out of my league. I will check for any electrical connections only if I know where I'm looking. I appreciate all the help that your giving me.
