Cruisin'
Out in the shop, building something cool!
Its time to flush the coolant in my 81 for the first time (for me, hopefully not for the truck
). I've read the FAQ in the 80 section regarding this procedure, but of course this is for the gasser. Any suggestions on doing this for the diesel, and most importantly, where is the coolant drain on the engine itself? I've searched, but I have not found 
I plan to drain the coolant while hot, then fill everything with fresh water to flush the system, then drain again and refill with coolant and de-ionized water.
That's my plan, now fellow mudders, please do what you do best and educate me!
