Use green....50/50 or 60/40 if your up north. Also if you plan on using a non nitrate make sure you clean your system out thoroughly. Carpet cleaners use a descaler...this will remove most build up...thoroughly wash out then...change your hoses...then fill. If you plan on mixing it yourself. Make sure you use distilled. (My dad still does)
IAT, OAT, NOAT, HOAT
If you can check your 404 manual.
One other option and is pricey....waterless coolant. Like Evans racing coolant. Works very well. About 4 times more expensive.
