Is this something I can do myself? I looked around the web and found some information, but it appears that much of the instructions vary wildly from model to model. It generally didn't sound too difficult (I've been doing my own Oil Changes and A/C recharging for over 10 years now...) but there were a LOT of different methods mentioned, from removing the pan to drain it (and change the screen while you've got it off) to draining it out of the main line going to the radiator, to finding the fill and drain plug and doing it that way (which sounds like the most reasonable answer, but didn't look like it did a good job at getting everything out. They also say to refill it through the dip-stick tube?!?!?!?!??! I KNOW I don't have a funnel ANYWHERE near that small!!!! Can anyone point me to a reputable instructional web site? In case it matters, we're dealing with a 1995 Nissan Pathfinder 4WD with the Automatic Trans. but if it goes well I'll also be doing my wife's 2002 Hyundai Elantra 5speed Manual.
