What's the proper conversion from r12 to 134 of 1996 sentra LEC aircon

[amateur37]

Newbie lang dito , Ask ko lang kung ano proper conversion from r12 to 134 ng 1996 sentra lec. Yung napagtanungan ko na A/C shop sabi flushing lang daw at palit ng oil, drier ok na daw sa 134. Di ba masira ang compressor, ano kaya effect sa lamig, hihina kaya o pareho lang ng lamig ng R12. By the way, original p lahat ng nkakabit sa aircon. advice naman sa A/C shop na mahusay at di tsambahan ang gawa. please kindly post all suggestions, thanks in advance.

as far as from my research. dapat din yung o-ring palitan.

have no idea to the effect to the compressor and effectiveness of the conversion.

natawa lang ako, when my father asked the mechanics about the costs. 25k daw sa convertion. lol

Kung original na R12 yung system, hindi mo na kailang pang inconvert sa R134a, dahil available pa naman dito sa atin sa Pinas ang R12, just unless na may ibang dahilan, e.g. sabi ng LTO kailangan R134a na para marenew mo yung registration ng sasakyan, IMHO other than that hindi mo na kailangan magconvert.

May ilan kasing requirements na kailangan para sa conversion. Bukod doon sa flushing at oil change, as rion suggested, dapat lahat ng o-ring palitan, kailangan palitan din yung service port ng pang R134a, in some extreme cases baka kailangan mo ring palitan ang iyong condenser to achieve the best performance.

sir nakapagkonver na ho tayo ng ganyan..kaya nagpalit ako ng compressor(kaya ko lang pinalitan dahil maingay na,parang merong kumakalansing),drier at expansion valve..sa condencer ay hindi..ang comprsor na para lang sa r12 ay design sa para lang dito..mas mataas kasi ang ipapasok na freon dito tulad ng r134a..in the long runsisibakin din nya ito o wawasakin..ang mangyayari ay back to square one ulet ang trabaho..salmat

how about the freon/oil ratio. same lang po ba? since 134a uses less freon if I am not mistaken.

sa r12 to r134A conversion ,maglagay ka ng 70% r134a .
sa lubrication naman use ESTER synthetic oil , kung ano ang recommended oil capacity yun ang ilagay mo.

this is something else. all the textbooks, manuals and conversion instructions prescribe poly alkyl glycol lubricant (PAG), similar to tf39 aircraft engine oil and not polyol ester (POE)

^^ all cars manufactured w/ r134a systems use PAG oil ,we use PAG oil manufacturing Chrysler vehicles here in Canada and I once stationed at AC department working w/ ac systems.

i use ester to convert r12 to r134a systems its because of the compatibility of the old capella oil and ester oil .

we don't have to flush the whole system as once believed .

i have been using ester oil strictly for conversion only.

if working with original r134a systems i always use PAG oil.
