Best and effective radiator coolant

[EVO-V]

If your engine isn't operating at optimum temperature, wouldn't it strain your engine and make it work harder? Why do you want to bring the temperature down? Is your vehicle a daily driver?

If you overload your vehicle, in the cases of delivery fleets and reefer vans, every bit of heat exchange performance counts.

Not a lot of room to put in a larger radiator underneath an L300 or Isuzu truck-van.

We actually refitted our isuzu elf with a 4be1 engine with a bigger radiator. Maluwang pa eh. New brackets for the bottom holder of the radiator lang but from 2 rows naging 5 rows na ngayon. It was consistently having overheat problems due to a small problem with the cylinder head that can't be refaced anymore. Now we don't have any more problems with overheating. Although a converted van like this one may actually have a smaller radiator to begin with.

I use yung extended life coolant from Caltex. From what is readily available, it is bang for the buck imho since good for 5 years or 200,000kms of use for 50% dilution. It's just me though.

But yeah, there may be better coolants out there.
