如何給車加冷媒

[/size]]家有兩日本車皆十年車齡,今年夏天特熱, 冷氣好像不夠冷, 是否可以自灌冷媒? 要從何處下手 ?

打開汽油蓋子, 有好幾個灌液口呢, 那個是正確的冷媒灌口? 就有教於亞城能手, 無任感激.

You can buy a can of R134 and simple gear to re-charge the refrigerant. It costs around $10 for both in auto store or walmart. Since it is designed this way, you will not miss the service port which will be connected to the charge gear. A very easy job. Some R134 contain leak-stop which cost a little bit more but I do not think the leak will totally stop.

Walmart 就有卖的。买一瓶冷媒，要带压力指示表的那种，瓶上面有详细说明。
1. 打开所有车窗，启动发动机，打开空调，温调放到最冷，风扇放到最大。
2. 从低压端接入冷媒瓶，空调机正常工作时，冷的那根管子是低压，看看压力是否正常，如果压力低，再加媒。

不要超过规定压力，不然会损坏压缩机。如果加媒后不久， 压力又减低，系统漏气，需专业人士检查。

感謝啦 好心又好意的人士.
