Review on Enhanced Robinair 75260 Coolant Refiller Featuring Air Lock Prevention by Peter Tennant

I used this tool to drain and fill our Toyota Highlander and Nissan Maxima. This tool makes filling the system very easy. This allows you to drain and refill coolant every 3-5 years. Works perfectly with my 2.5 hp compressor. and an 8 gallon tank. It barely made it to "25" but was green and worked like a charm. I filled a 5 gallon bucket with 1 gallon distilled water and 1 gallon Toyota Red (concentrate). 2 gallons was a lot and I have 1/2 gallon left.
