[DML] Re: Radiator Story

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

Sounds like as good story but I ain't buying it. A radiator can be
flushed, you might have to do it with acid to get the gook out but it
can be done. Now here is what I believe to be the real story. The car
keeps losing coolant. The previous owner replaced the radiator
thinking that was the problem. Didn't help.  Since he still was losing
coolant he put some stop-leak in and that plugged up the radiator but
he was still losing coolant. The REAL source of the problem are the
seals on the top of the motor under the intake manifold. When you have
leaks under there you never see the coolant on the floor, it gets
caught on the top of the motor where it is evaporated. You need to do
the Master Water Pump Kit. Fun job. Don't skimp on it. The motor can
take a lot of abuse but it doesn't take kindly to overheating! If you
think it is expensive doing the Master Water Pump Kit wait till you
overheat the motor! Do all of the hoses, belts, idler pulley bearings,
water pump, seals, gaskets, thermostat, and Otterstadt switch and
seal. Before you reassemble the top of the motor pressure test the
cooling system up to 15 psi for 15 minutes. It has to hold tight with
NO leaks. You should also replace the header bottle with the metal
one. With all this and your metal radiator your cooling sytem will be
bulletproof. The only way to improve on it would be to do something
better than the fan fail bypass, like the Fanzilla if you can find
one. This seems to be one of the initiation rites for Delorean owners
that find a low mileage "gem".
