Review on Enhanced Robinair 75260 Coolant Refiller Featuring Air Lock Prevention by Ryan Saxton

This works great except for one thing. The only reason I bought this in the first place. I work at a dealership and I work on Chevy Volts. It is important to remove all air from the battery cooling system. So the reason for this purchase, except it doesn't work with the smaller volt bottleneck. It works well on all other Chevy vehicles but not the Volt. Spring.
