Actually they already repaired one of the sides of my aluminum radiator. Yung sa upper part merong butas. The solder is black. I don't know what it's called. Priority ko talaga is cost. Almost 10 years narin tong sasakyan. 110,000km on the odo na. No problems aside sa radiator. One last chance tomorrow, I'll bring it back sa pinaayos ko hopefully it will be fixed for good.
