Tried posting on rx7club and didnt get much help so i figured i would come here. Well i just had a new koyo n flow radiator installed, and got the car back a week or so ago. The first 25 minutes or so the car runs perfect, then my water temps go up to around 100-109celcius the idle drops to like 600 and it almost stalls (stalled a few times). Also my coolant light comes on everytime i go to drive it, i continuously have to top it off and i see no coolant anywhere. Let me know what you guys think... - Eric
