Chinese cheaper than say Desert Cooler, PWR is most expensive.
Few i know have used all three, no issues at all.
For more effective heat transfer from engine to water, do not use ethylene glycol, ie the usual common anti freeze coolant, since wgen, in this country do we freeze!
Instead
Use product like Redline Water wetter, or Penrite Sin coolant, these do not contain ethylene glycol, are dafe to "dum"on a race track, and actually cause more efficient transfer of heat from hot metal into tje eatwr, and cause better air cooling as itasses through whatever radiator you use. It also makes our original equipment radiators work better!
