I have a 1976 Datsun 280z, I've had it since I was 16 I'm 25 now and it's a great car. I've been all over the western United States from Los Angeles to Vancouver, b.c. Canada. I live in california, Oregon, and Washington and my z has been there with me every step of the way.
Now I have a problem. My z starts, runs great until it gets hot. It dies out once it gets over heated. I got a new aluminum radiator that I thought would keep it cooler but it doesn't seem to. The weird thing is after the z cools down it starts up like a champ. Oh yeah outside its 102 degrees. I'm sure that plays a part.
