Coolant in Cabin... 89' S10

[Barefoot]

I know the newer generations are hailed as terrible to do. I found a picture walk through to give you an idea but I would say on an 89 it would be easier.

89s are way easier then them
on the 89 s10 w/o a/c they arent all that hard. if u have a/c its still not that hard but takes a lil more time. there are some areas that are a bitch but 90% of it is easy.
