If he put stright anit-freeze in drain half the system. It will keep the system tooo cool and not let it get up to operating temperature. Therefroe it WILL drink more gas than actaully should cuz the engine isnt at the temp it should be. The freeze protection is 35 below zero. thats all you need to know. ALWAYS 50/50 mix!!!!

Did some math and figured out I was wrong.
Assumptions: Antifreeze was originally a 50/50 mix.
Book shows capicity 8 gallons but Cookie says his only holds 7, even draining the block so I used 7 gallons.
After adding the 5 gallons of antifreeze, the mix would have been 14% water, 86% antifreeze. This would cause the engine to overheat and could cause damage in some circumstances.
If you drain 1.5 gallons out as I originally stated and replaced with distilled water, the mix would end up being 33% water, 67% antifreeze, still way too high.
To reach a 50/50 mix, you would actually have to drain 2.9167 gallons and replace with distilled water.
If you drained half, or 3.5 gallons and replaced with distilled water, the mix would be 57% water, 43% antifreeze; this mix would not protect the engine from sub zero temps but would do a better job of cooling the engine.

Thanks, guys for all your help.
I picked up 3 gallons of distilled water this afternoon and I'm going to drain out 3 gallons of my bright green coolant and replace it. By the way, the local market(this is Hawaii) charges $3/gallon for the water!
Aloha!

A gallon of distilled is less than $1 here in CO.
