I change the radiator today,after I put the new one( actually not new one, it is a used one) in I did a test drive on the high way, but the coolant temperature goes high after 9 min about 60 miles/hour so I shut the car down and restart again, the Temperture drop to half and when I start drving it, Temperture goes high again and I DON'T have heater, I used to,I have heater before I change the radiator.

I touch the radiator, it's hot so it means the thermosta is good maybe... but the problem is the coolant in the raservior is cold....
