Aircon / Radiator Problem

Mga sirs

Question lang regarding Aircon/Radiator problem

So sa unang 15mins run, okey yung aircon but after that yung buga nia is wala ng lamig tapos tumataas yung temp gauge sa dashboard. so pinapatay ko yung aircon.

Ok naman ung sasakyan sa long run pag wala ung aircon.

Then, malakas consumption ng coolant. naubos yung 1/4 part ng overflow tank. wala namang leaks sa tubes. Wala ring white air sa discharge ng exhaust pipe. wala ring oil sa radiator pag inalis ko yung cap.

Ano kaya problem dito mga sirs? Dahil ba sa thermal switch ng compressor na pag naghigh discharge si freon ay mamamatay ang compressor?

Pero yung root cause, bakit nauubos yung coolant? dahil ba sa sirang cap?

Eto sirs condition ng cap



San kaya pwede ipaayos to?

Thanks in advance.

my guess? your aux fan is defective. it might not be turning as fast as it should. that is why, it seems to be working ok when you look at it. hindi na malamig aircon, overheat pa engine. when the engine overheats, the steam escapes to the coolant reservoir, heating it so that it also turns to steam. ubos radiator coolant, ubos reservoir coolant.
look for the same model vehicle as yours, and observe how strong the air movement should be.
good luck.
