How to Improve LXi Engine Cooling Performance

[al perna]

Thanks , now how did you go about the 3/4 gal @ mile ? now if we use 1 gal per mile and use it 25% of the grade s millage , how much water must we hold on a 8 mile climb at 118 degrees with a 8% Grade . ? you see I didn t even need it on a recent trip with many tough climbs this summer in Colorado . But I do think Chuck was asking for the ability to go faster , not over heat .
