Ok
It is messy and a pita...
I replaced both lines, the one from the block and the one to the radiator. You don't have to remove the radiator, but you do the ps pump.
Start from underneath and remove the two bolts that hold the end to the block.
Obviously drain all the oil first

let it hang. If I remember, there was one other bolt holding the line to that dealie...I fought it for 2 hours trying to get the bolt out. After lots of cussing and screaming, went to 4 hardware stores to find wobble extensions. Took the two longest ones and a socket, came in from the front and it lined right up and had the bolts out as quickly as I could turn the ratchet. You will first bang and get pissy trying to pull the lines out. Turn them counterclockwise and they will come right out. Can't think of anything else, other than there are two gaskets for the block side, couple little o gaskets, and don't forget any of them. I think both lines cost under $100 and I now have a leak free Typhoon. If ya have any other questions, let me know, it is still somewhat fresh in my mind, and if you are patient, unlike me it can be done in under an hour.
