reservoir date stamped ?

[nnewell]

Last week on a trip, anti-freeze started dripping in front of the right rear tire.
I headed for the nearest garage dreading a cracked reservoir ( miles from a parts store ) turned out to be a missing hose clamp on a reservoir hose - it had never been installed. Got me to thinking maybe the reservoir has been changed by the
P/O. So before I pull all the carpet back out to check for a date of manufacture does one exist and where on the tank is it ?

Thanks,
Nick
