When a Delorean is modified from stock it is very difficult to advise on how to fix. The best advice is to get the manuals and try to return it to stock. You could also have other problems that are causing the overheat like leaks, air, bad head gaskets, etc. I also recomend uprating the circuit breaker and getting a Fanzilla. When running the A/C you override the otterstadt switch so the fans cycle with the compressor. Join the local Delorean club and tap into their expertise.
