    [QUOTE=colt;2354407]sir malamig po yung tubo. ngpapawis po..ngayon araw tinry ko palitan ng mga rad fan. obserbahan ko bukas pag tirik ang araw.[/QUOTE

    sir pag ganyan ata... not sure... hindi nga nakadikit mabuti yung titi ng thermostat mo sa evaporator... or

    ppwede din sir... hindi properly insulated yung evaporator housing... imbes na sa cooling coils dumadaan yung air... sa gilid gilid ng evaporator coil lang dumadaan yung hangin....

    sir.. hindi ko po alam... pero nakikita ko yung gumagawa sakin.. may no. ata sya tinitingnan sa exp. valve then may computation pa sya... tapos may bilang yung pag pihit nya sa loob... not sure.. po ha..

    pero kung may bara.. alam ko pinapalitan na yan...

    oo nga po pala... pag kakaalam ko dating fabricator po sila ng expansion valve and condenser...

    same problem kay TS..

    hindi malamig pag mainit.. tapos kelangan naka todo yung thermostat kasi pag inukot ko lang kahit onti ng hindi
    naka todo hindi na ganun kalamig yung buga.. minsan iinit pa.

    tapos yung tubo ng high pressure mula compressor mainit minsan.

    sa umaga lang malamig at sa gabi.. ano kaya sira?

    Sir sa gabi naman panay ang automatic nya kahit naka idle kasi nga mababa ba setting ng thermostat ko kaya panay automatic, pero pag tirik araw at naka stop ayaw na mag automatic, pinapatay ko na nga lang ng ilang secs para lang wag mag high pressure

    Is it really that HOT lately? Bagong linis aircon ng Advie ko (two weeks). Expansion valve and dryer, last year pinalitan. No leaks. Pero nung ginamit ko kaninang tanghaling tapat and medyo matraffic, hindi ako kuntento sa lamig.

    could be a problem with your thermostat

    greenhouse effect nga lang siguro chief. yung sakin malamig naman yung buga kahit traffic pa pero halos di kaya palamigin pag tirik araw.

    yung mga nasasakyan kong taxi na mga Vios 2nd gen eh hindi rin kaya (or nasaktuhan ko lang a few of them sira aircon). baka sa panahon lang talaga :sun:

    ^Yan din problem ng AC ko before. After cleaning, ganun pa din. My mechanic found the problem. Its the AC pressure switch. When pressure goes above normal, i.e., mataas ang ambient temp, it sends a signal to the aux fan to go into high speed. Pag sira ito, normal speed lang ang aux fan kaya di lumalamig and naka high pressure.

    In your case sir, I suggest you check what triggers your the speed of your aux fan. Pwede din kasi sa temp sending unit, or mahina na ang fan.

    b0y37,

    Baka mahina na din ang rad fan nyo sir or pwede din na madumi ang condenser. Pabugahan nyo ng pressure washer or kahit hose habang naka hi pressure sya. pag lumamig, either madumi sya or mahina ang fan.

    Since adventure yan, pa check nyo din yung fan clutch at aux fan.

    ^Madami factors yan sir. Yung mga unang labas ng toyota uses serpentine type na cooling coil. Which has limited rows compared to the laminated coils with several rows. 2nd is your compressor. If your van came with a since AC, then nilagyan ng dual AC without upgrading the compressor, di rin kakayanin. I also doubt those locally manufactured/fabricated equipment's build quality. Pwede din kasi na design fault ng manufacturer. Kaya usually in later models ng toyota, made for tropical weather na talaga yung AC.

    Going back, yung pagbuga ng tubig sa condenser will temporarily solve the high pressure situation since it will help the aux fan in converting gas to liquid. this process is interrupted by a weak aux fan or clogged condenser fins.

    I think yung Sanden 508 is good for dual AC. Yung drier kasi needs to be replaced periodically. Specially if nasiraan ka ng compressor. It works by removing moisture and metal particles. Sakin, I replace it every 3 years.

    Check the cold line if malamig and nagpapawis. It should be freezing cold, pero not to the point na nagyeyelo. If not, pwedeng kulang sa freon.

    The best way pa din talaga is to hook it up sa AC gauge to know the actual health of your compressor.

    Depende sa shop sir if equipped ng refrigerant recovery machine. Ideally palitan nyo na lang freon ng Eufron para sure na malamig.

    OT:
    My Cefiro has sprung a leak somewhere. Hindi mahanap sa mga lines sa engine bay. Hassle kasi just had it cleaned last June. Sayang din kasi it can go as low a 3 degrees sa vents. Gastos na naman.
