Radiator & Coolant for VY LS1

[mechatron]

Hi Guys, my existing radiator is cracked and I’m in the process of selecting a new radiator, new hoses and coolant and just needed to confirm a few things:

1. Is an ADRAD a good choice for a radiator?

2. A lot of people talk about Nulon products so I wanted to try their coolant. Which coolant am I best off getting out of these two?



OR



3. I haven’t been to the shops yet to read the instruction labels on these coolants, however can I mix with out of the tap water or must I use demineralised water?

4. With a new radiator and everything flushed, how much coolant/water mix do I need? 12L, 14.5L??? And is it generally 50% water, 50% coolant?

Thanks guys
