Hi In my opinion 220 and higher is way too much. Even with the A/C on in hot weather the temperature should not reach 220. My first DeLorean was an auto (runs hotter because of trans cooler and higher rpm for given speed) has never got even close to 220 all in hot Florida. It usually stayed around the quarter mark and only rose to just below 220 when stopped. Then the cooling fans switched on and the temperature dropped down. It wasn't like that at first. It was running closer to 220 all the time until I replaced the radiator. I installed an brand new OEM radiator and never worried about overheating again. My current car is starting to develop the same problem and I guess I will look into getting a new radiator soon. Maybe you should change yours as well since everything else is good. This is cheap insurance... Good luck Tom Niemczewski vin 6149 (in Poland!) Google earth: 52°25'17.30"N 21° 1'58.00"E tomciodmc@xxxxxxxxxxxxxx www.deloreana.com > So here's my question?
