be4 i use single layer copper radiator that heavily blocked....so i use double layer copper radiator.......my pricelist

Double layer copper radiator-Rm220(trade in old rad RM30 bux)
Toyota coolant-Rm18(friend price )
Workmanship:Drop of sweat becoz DIY

Boss, long time didn't drop by here.... MIA??? hahahaaa....

Anyway regarding ur question, since u already change the radiator... u could use these guidlines for further references. U can opt either:

27mm aluminum radiator (RM190 new)
or
47mm aluminum radiator from Jasma (RM290 new)

Wats the differences??? Both are made from aluminum and effective in dissipating heat compare with copper material. Copper is much more effective is drawing the heat from the engine and coolant but slightly poor in heat dissipating comparing with aluminum. As for the thickness, thicker radiator holds more water. The more water it holds, u need a better/stronger radiator fan to fully utilize the radiator. And ofcuz ur thermostat muz be in good working order or else u gonna have problem with the temperature like cold start problem and operating temp problem.

I've been using Toyota Coolant mixed with R.O water on my 27mm double layer radiator for nearly 2years and sold off the radiator (upgraded to the 47mm rad) to a fren using the same coolant mixture. So far no problem with it. IMHO, it keeps the water from rust formation and it does not harm the radiator so far lah.
