Dorman part #47065 is the pack of replacement elbows you will want. (There'* another lower down).
Pull the strut tower bar (if equipped)
Drain off about half of the coolant
Remove overflow container from strut tower.
Remove the alternator
Remove the alternator bracket/tensioner assembly. There is one bolt that you won't be able to see at the back of the bracket.
(elbows are facing backwards in this pic)
Pull out the old pieces of the coolant elbows (bypass) and wipe out the holes where they go. Lube the new o-rings with oil or something and line up the elbows in the tensioner bracket. Put the bracket back in place and bolt it back in. Put alternator back on, coolant bottle, connect power, fill with coolant and you are all set.
This job pays about .5 and shouldn't be that bad for a mechanic.
