I ran across an old Prestone Flush kit I picked up eons ago, and now wonder which hose I should be installing it on. Counter to the kit's instructions, both hoses coming from the firewall "appear" to go to my Grand Prix's water pump. There is a plastic T/garden hose adapter I am supposed to insert into one of these hoses.
The question is... which one should get the adapter?
