So, I was out for a Sunday on the '04 yfz450 and my bro noticed from behind me that my overflow was out of water. I found my water pump leaking at the base. 1 question is what type of radiator fluid do you guys use? I don't need anything special (aka expensive).

Second question is I found hi-flow impeller from a place called whitenuckleracing.com for $40 bucks. Should I replace mine?

 

coolanol is good stuff, im not sure what other good stuff people use prestone maybe

 

Where do you get it Warrior357? Order off the internets, Wally Mart, or ????
