[DML] Re: Cooling System Problems - still





Putting an overflow bottle on is a no-brainer. When I changed over to
a metal header bottle I was no longer able to check the coolant level.
To fix that I could have used a clear hose with two fittings top and
bottom into the header bottle but I couldn't find any clear hose that
could take the pressure and temperature. It was then that it made
perfect sense to just add a hose to the fitting under the pressure cap
and run a hose over to an overflow bottle. I mounted mine just ahead
of the carbon cannister on the left side of the engine compartment and
ran the hose over the motor. You need a fairly large bottle because
the Delorean has such a large volume of coolant so there is more to
expand and contract. You also want to try to keep the overflow bottle
as close to the same level as the pressure cap to avoid creating a
"head" ie, a differential that can cause a siphon. This overflow also
helps to prevent any foaming and it reduces the air in the system so
it should reduce corrosion. The biggest problem is you have to have a
TIGHT (leakproof) system because it is almost always under pressure
and is usually at a higher pressure longer because there is no air in
the system to compress. As soon as you start to heat the coolant up
you have the system under pressure. Be gentle with the fitting under
the pressure cap on the header bottle. On mine it was just a tight fit
and when I pushed the hose on it fell out. I epoxyed it back on so it
wouldn't leak. Any generic overflow kit will work. This is one of the
cheaper (read inexpensive) upgrades and is not so difficult so just
about any owner could do it.
