Why not the usual name - COOLANT RECovery/SYSTem, the bottle that found it's way under the hood to catch and return coolant as it expands and contracts.
No pump needed!
Came with the police package and towing package in 1972, and I think was standard on everything starting in 1973.
Thanks! Such things can keep me awake for the better part of the night.
