Alam ko hindi basta pinapalitan ng 134a ang ac mo, marami pang modification ang kailangan gawin sa cooling system mo. May sticker sa sa may engine bay kung 134a na ang ac mo.
134A na yan. But if it's R12 you can convert it to 134A, it's not that complicated. You just need to replace the dryer, drain the oil, and if budget permits a new compressor doesn't matter if it's R12 or 134A spec.
