Bump / read on pressure testing your coolant system, and how to. You can make a kit from basic parts from auto part store. And run it out of your hood to the drivers window. You dont want the pressure to go past a certain lb or go up as you hit the fast pedal. If i remember right, mine did not go past 12lbs of pressure after it warmed up while driving, which was still good. Also search for the then "new" full level your reservoir when cold. I believe they made a sticker for it, but i keep mine right where the fluid is almost level.
