Re: Question about steel bottle

["basfe25" <dmcman73@xxxx>]

I've had an unpleasant experience with a plastic bottle cracking. 
The bottle was on my Jeep, It pretty much has the same setup as the 
Delorean...sealed Radiator and a plastic coolant bottle (pressurized 
closed system). My bottle cracked spilling fluid everywhere. I've 
also repaired other Jeeps where the bottle actually ruptured 
spraying antifreeze all over the windshield. Heat is one of the 
factors that "dries out" the plastic (yellow discoloration, becoming 
brittle) plus with all the expanding and contracting it goes through 
it's only a matter of time for it to just crack.
