never open a hot radiator with your bare hands! especially while the engine is running! kung di di lang 2nd-degree burns makukuha mo, major injuries pa kasi pressurized yan-->imagine open a shaken unopened cola bottle,diba tatapon, now gawin mong 100+degress C yan...

the proper and the long way is palamigin mo muna! then buksan mo-->kung sa gas station ka,tubigan mo ang radiator until it cools down.

patayin mo ang makina pag malamig na, try to use your long tire wrench or pang angat ng jack to gently open the cap(kung walang button to realease the pressure of the system built in the cap), slowly pag nag loos na, hanatayin mo munang sumingaw.. pag wala nang singaw alisin mo na ang cap ang refill it na with water...

nope, main fan shoul run only kung naka-abot na yung preset temp ng temp sensor(kung stock system), pwede mo ding derecho or always on, pero madali masisira ang fan mo...

ganun talaga pag buhay a/c buhay ang fan-->condenser reasons naman kasi,e..
