Re: Overheating...

Check that the cooling fans are rotating correctly ie; pulling air 
into the radiater. Check that the fans are securely attached to the 
motor shaft. Check that there is no blockage of the grill in front of 
the radiater. I remember someone posted that they had a license plate 
there and after removing it the car ran cooler. Upgrade the circuit 
breaker for the cooling fans. If you have the older otterstadt switch 
installation where it is on top change it to the newer version where 
it is on the bottom. If you cut the pipe you only need a new hose. Do 
not overfill the header bottle, if you do you will constanly dump 
coolant. Add a coolant recovery bottle. If you suspect a combustion 
leak there is a test you can have done on the coolant for the presence 
of combustion gases. If the car was severly overheated in the past it 
is possible you blew out a head gasket but it is't common on the 
Delorean unless you really cook it. It is also possible you have a bad 
or sticking thermostat, slipping fan belt, kinked hose, and so on. An 
engine way out of time can also cause overheats. Start with the ideas 
in the order I posted as they get more compex and expensive as you go 
down the list. I also recommend Fanzilla but it won't correct an 
overheating problem. If you don't know when the coolant was last 
changed flush and refill with fresh 50-50 soft water and anti-freeze. 
Pressure test for leaks. If you have ANY you will constantly pull air 
into the system and the auto bleeder can't keep up. 15 psi for 15 min!
