JDM 1994 Urvan antifreeze recommendation

[horizon1177]

The 1992 Nissan Urvan, 2.7 diesel (no turbo) needed antifreeze, the manual said to use ethylene glycol antifreeze; at the time, apparently it was pretty simple: EGW+phosphates and no silicates. Today that's complicated, there is no such animal anymore... The JDM importer said to use Zerex Asian green (Valvoline) PHOAT, has no Si, 2-EHA, amines, nitrates or borates. I emailed Nulon (Australia) who recommended Nulon Green Premium LL, a "hybrid addative technology" no phosphate, no nitrites no amine but yes low silicate. Methinks they actually have Urvans running around down there, where we don't up here. I'm uncomfortable running a hybrid organic type antifreeze on the older JDM vehicles (this is my first introduction to it), and really shy of the silicon too. Has anyone got experience with it? If not, that's my research & best guess, recommended to me, on what to use, I'm certainly no expert.

Older Nissans in America used IAT conventional green. I'm a little nervous introducing new chemistry into an old system, but I've had good luck with G-05 and P-HOAT universals (like Peak Global or 10X) in older vehicles that came with green originally.

Have you looked into the John Deere antifreeze or any of the tractor ones? Might find something to fit the bill in those.
