Antifreeze for the Suzuki Jimny
The Jimny is small, but its duty cycle is among the hardest. In the mountains, in mud or in snow it works at low speed and high revs, so the engine sheds plenty of heat while airflow is practically absent. Suzuki is named on the Valvoline Zerex Asian Blue data sheet.

Cooling system volume (litres) roughly three to five litres depending on the generation
Off road means no airflow
On a motorway, air enters the radiator by itself and the fan has almost nothing to do. Crawling five kilometres up a track is the opposite: the engine is fully loaded and only the fan moves any air.
At that point coolant temperature climbs toward the limit, and what matters is where it starts to boil. At 50/50 that is 128 °C, and at 60/40 it is 133 °C.
If your Jimny regularly goes into the mountains, a 60/40 mix makes sense twice over: it protects to −48 °C in winter and adds five degrees of boiling margin in summer.
Mud in the radiator fins
After a day off road, mud and plant debris stay in the radiator fins. You cannot see it from outside, because the fins hide behind the A/C condenser, and the effect is the same as internal deposits: heat no longer reaches the air.
So after every serious outing, wash the radiator carefully at low pressure. A high-pressure jet bends the fins and makes the problem worse.
Cleanliness inside the system is the fluid's job: Valvoline Zerex Asian Blue is silicate-free at under 10 ppm silicon and is hard-water compatible.
