radiator fluid?
Is it necessary to put the recommended "Nissan J fluid" in the radiator?
I was going to put some Royal Purple Ice in with typical Preston 50/50, but I wanted to double check to make sure it really wont damage the radiator.
Also, while I'm asking. Is it ok to put the Royal Purple or another Synthetic Tranny fluid in, as well?

Nissan Matic J is the automatic transmission fluid, not the coolant. ATF in the radiator would be very bad. Where are you reading that Matic J goes in the radiator? I think you got something confused. The OEM coolant is Nissan OEM coolant, definitely NOT Matic J Automatic Transmission Fluid. Go with the the royal purple ice and prestone 50/50 in the radiator and save yourself a very expensive cooling system repair bill

Not trying to confuse things, but the cost of a gallon of Nissan coolant is about $34 from the dealer so I'd sure like to know what a good aftermarket coolant is.
I'm pretty sure there are specific coolants for aluminum and non-aluminum radiators. Anybody know what the stock radiators are made of?

Up to a point the water quality is more important than the coolant brand!
Ethylene Glychol is ethylene glychol. Now the 3% additive package has a finite life.
Luckily an all aluminum system so the hoses may fail before the distilled water and coolant do.
But still important to analyse the mixture to maintain minimum functioning additives at least every few year [30k].
Budget for a new radiator every 10 years or 150k if you desire as new cooling.

This is a not so simple question as simply trading one coolant for another. On the one hand, many folks believe that Nissan "requires" phosphate and silicate free coolants. The Nissan L248SP Advanced Formulation P/N 999MP-AF000P says " - no amines,no silicates,which may harm water pump seals, or borates that may cause aluminum corrosion and pitting. L248SP Engine Coolant provides long lasting protection for aluminum,cast iron, and all other engine components." Also " always use deminerlized or distilled water. However, there's other info that suggests that the Japanese "big-three" subscribe to a hefty dose of phosphate in their coolant as their quick-acting hybrid chemistry. OAT can take up to 5,000 miles to build up its full depth of plating on bare metal cooling system parts. Should a stray particulate "scratch" the OAT coating, the dissolved phosphate will immediately act as "bandage" protection until the OAT can re-establish itself.
So, the simple question may require more expertise than exists between those of us that have answered so far. I would contact an Infiniti dealership and ask the service managers opinion.... in fact, I'd call 2-3 since they often disagree. In the end, I
