Looking for the best one to put in my new aluminum radiator. I herd there was a coolant that lowers engine heat by like 10% better than the others? which brand is that? and what exactly will i need to buy along with this to mix. 50/50? Iv never changed my coolant before. lmk

Thanks.

Dont understand why this is in FI, but cant beat OEM

look at the bottle of what ever you use. there is a % on the back that will tell you the best level of protection.

water wetter works pretty well.

ifthis is a track car, please use only water, if anything bad happens, it is faster and easier to clean up water, than it is glycol.

if you do just use water, get a cooling system conditioner for aluminum engines. it keeps from coroding the aluminum parts.

Get direct from Honda (find out exact grade in handbook) but their stuff is the best for their engines! I've been warned harsher coolant can easily corrode bits over time, and only ever use deionised water... too much crap in tap water!

check out this stuff called water wet-er i think this company redline makes it. i think you can find it at any autozone or pepboys.

redlineoil.com (this was on the bottle) water wetter [cost $10]
it suppose to keep it 20 degrees cooler

yeah, whatever you use, use distilled water with it instead of tap water, no minerals/ions so it doesn't conduct electricity and corrode anything. I don't recommend using only water, the antifreeze does other things like lubricate the seal on the water pump too..
