RE: [DML] Re: Coolant Coming Out



I suspect the problem is that you are not properly bleeding the system.
I had the same problem early on when I underestimated the bleeding
process.  When air is trapped in the system it expands at a much higher
rate than the water.  Therefore, if (when) you have a bubble of air at
the water pump or the radiator it will swell to many times it original
volume as the system heats up, forcing out a gallon or so of water. You
shut off the car, let the system cool, add a gallon of 50/50, form a new
bubble, and start all over again.

Short term you need to bleed the system at both the thermostat housing
and at the small hose at the top passenger side of the radiator and get
the air out.  Be very careful with that radiator hose if you still have
a plastic tank radiator - the barb where the hose connects to the
radiator was fragile 25 years ago, guess how it holds up now.  Make sure
to fill the system with 50/50 - even if your spewing a gallon a day you
have to use the right stuff.  Bleed it properly and you probably won't
spew.

Even with bleeding its helpful to squeeze the large hoses in the engine
compartment to help work out the bubbles faster.

That done, order a new cap for your coolant bottle, and bleeder kits for
both the thermostat and the radiator.  All in all you will spend less
than you have been spending on Prestone the last week, and your problem
should go away.

Everybody has the thermostat bleeder kit and radiator caps,  as far as I
know only Toby at Delorean-Parts.com also has the radiator bleed kit.
Be sure to confirm with your vendor which coolant bottle you have when
you order the cap, is it plastic (original and needs to be upgraded or
you will be buying more Prestone soon), it could be Stainless, aluminum,
or a European bottle which I think is steel but finished black.  My
Aluminum bottle does not use the original cap, so make sure.

Keep cool.
