I just replaced EVERY coolant hose on my 95. The top radiator hose I replaced in October since it blew out on my during autocross. And that hose had been replaced sometime in the past. All the other hoses were original. I replaced the bottom radiator hose about a month later (preventative maintenance). Then three weeks ago I replaced every coolant hose that was left. I bought the standard hoses from Rockauto. Then I replaced the hoses that were attached to the aluminum lines off the coolant fill tank.

A head up.....buy the heater control valve if you are going to replace the hoses to the heater. It is plastic and will probably break when you put it back in. I found one at Autozone...about $10.00.
