[DML] Re: Cooling System Problems - still

["Joe LoRe" <dmcjoe@xxxxxxx>]

You are missing the point. As you mentioned, if every component in 
the cooling system is operating at spec and there are no leaks at any 
of the components that connect to the cooling system than there is no 
need for an air bleed device at the thermostat. Unfortunately in the 
real world this is not always the case. When you consider the number 
of connections and components in the cooling system sooner or later 
there will be a leak. Any leak in the system will cause air to be 
drawn into the system which will eventually collect at the thermostat 
leading to an engine overheat condition. 

It's easy for people like yourself, who can easily diagnose, replace, 
and maintain the components you mentioned. Unfortunately for many 
owners, especially the ones that are distant from knowledgeable 
service centers or don't service their own cars a loose clamp could 
cause an owner to be stranded in his DeLorean. Worse yet engine could 
suffer permanent damage

You when you said "The BIG problem is too many cars don't have
a tight cooling system." You're exactly right; that is why the 
Overheat Protector is such a valuable item.

The overheat protector is safety device and does just what it says; 
it will prevent the engine from going into an overheat condition if 
air is drawn into the system. The side benefit of the device is that 
it eliminates the need to manually air bleed the cooling system.
