[DML] Re: Opaque Coolant Bottles (An Explanation)

["content22207" <brobertson@xxxxxxxxxxxx>]

Perhaps some explanation:

Do not confuse the "coolant bottle" with a closed type system
reservior (it's really just an expansion tank). It is located on the
pressurized side of the radiator cap and serves the same function as
an air gap at the top of an old fashioned radiator. As coolant heats
up, it expands to the cap. Any excess gets spit on the road. You can
fill it to the top if you want, but I guarantee that after cool down
there will be an air gap in the tank. This is normal. Since the
expansion tank is the highest point in the system, as long as there is
some fluid in it you're cool (assuming the rest of the system is
healthy). 

Be careful where you route the overflow hose. If it's pointed towards
the engine you may generate a cloud of steam and panic yourself
unnecessarily.
