Got my car running. Its not running well for some reason. However after about 20 minutes of driving the temp was rising a bit not high or anything, about the R on normal its a 94 GT. But when I check the upper radiator hose is hard a rock and no water flow. I cant figure why whether its the thermostat not opening or what. If anyone has any idea I would appreciate advice. Nevermind I let it idle for a bit and the thermostat opened up and started flowing, temp goes down to the O in normal when idleing and the R when driving.
