Re: Coolant Change

[jtrealty@xxxx]

Make sure to drain as much of the old coolant as possible and dispose 
of properly. Flush the system several times and refill with a 50/50 
mixture of a national brand of ethelyne glycol like Prestone. It 
should say safe for aluminum. The national brands have additive 
packages that prevent corrosion, lubricate the water pump, seal small 
leaks, are anti-foaming, and resist evaporation. While doing this you 
should consider replacing ALL of the hoses. Pressure test with plain 
water before refilling with anti-freeze to verify that there are no 
leaks. The system should hold 15 PSI for at least 15 min. Be sure to 
bleed the air from the radiater and water pump. Do not overfill and 
consider changing the header bottle to a metal one. There is also a 
continuous bleeder kit available. Check and replace both belts and 
maybe also the idler bearings. To make the cooling system completly 
bulletproof upgrade the cooling fan circuit breaker and install a 
Fanzilla. If you have money left over install a new radiater with 
brass end tanks. Since you are interested in prolonging the life of 
you Delorean don't forget to flush the brake and clutch systems with 
DOT 4 Castrol GTLMA brake fluid! Remove the windshield washer bottle 
and clean all of the crud out of that while you are at it. IMHO the 
cooling system and associated electrical components is one of the 
weakest areas in the Delorean but doing these things will make it MUCH 
more reliable. Although the car has some simularities to volvos there 
are many significant differences. Instead of looking for a volvo 
dealer try to locate a shop that works on classic or antique cars.
