Kako promijeniti antifriz u Chevroletu Lacetti

Svaki vlasnik automobila zna što je antifriz i zašto mu je potreban automobil. Bez te tekućine, djelo bilo kojeg vozila, uključujući Chevrolet lacetti, nemoguće je. Kako iscrpiti tekućinu za hlađenje iz ovog automobila modela i sipati novu nakon pranja sustava - pročitati dalje u članku.

Antifriz, zašto je potrebno gdje se izlije

Tekućina za hlađenje motora (ona se također naziva "antifriz", "rashladno sredstvo" i "hladnjaka tekućina") potrebna je da automobil obavlja brojne funkcije. Hlađenje motora je jedan od primarnih zadataka rashladnog sredstva, ali i druge funkcije, naime:

  1. Hlađenje hidraulične tekućine prisutnom u automatskom mjenjaču.
  2. Učitava crpku jedinice za napajanje kroz koju se nastavlja.
  3. Grije vozača u hladnoj sezoni, prolazeći kroz jezgru grijača.

Osim toga, sastav antifriza proizvedenih do sada uključuje posebne tvari koje suzbijaju pojavu razmjera i sprječavaju pojavu depozita. Međutim, vrijedi napomenuti da takve kemijske tvari imaju relativno kratko razdoblje valjanosti. Antifriz se izlije u poseban ekspanzijski spremnik, koji je u motornom prostoru.

Rashladno sredstvo ili antifriz, koliko često je potrebno promijeniti antifriz

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

Proizvođači preporučuju mijenjanje antifriza svakih 40-50 tisuća kilometraža kilometara, koji će u potpunosti eliminirati pregrijavanje motora. Stručnjaci koji rade za stotinu savjetuju se da promijene rashladno sredstvo najmanje jednom godišnje, inače hrđa može nastati.

Što antifriz odabrati, kriterije za odabir rashladnog sredstva

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

Izbor rashladnog sredstva treba se približiti vrlo odgovorno. Prvo pročitajte priručnik za održavanje automobila, jer se različit antifriz izlije u različite vrste motora. Postoje brojni kriteriji ključnih rashladnog sredstva:

  1. Temperatura niske kristalizacije.
  2. Otpornost na toplinu.
  3. Prilično visok kapacitet topline.

Osim osnovnih gore navedenih kriterija, rashladno sredstvo ne smije izlagati metalnu koroziju, koja se postiže uz pomoć posebnih inhibitora aditiva i ne bi smjela formirati pjenu tijekom rada jedinice za napajanje.

Zašto se ne može miješati bivši antifriz i nova otopina antifriza

U rashladnim tekućinama danas su tvari koje sprječavaju pojavu hrđe. Prilikom miješanja starog i novog antifriza, njihova antikorozijska obilježja značajno se smanjuju. Trajanje djelovanja antikorozivne tekućine značajno ovisi o različitim komponentama protiv korozije u njoj.

Dok su sadržani u antifriz u traženoj količini, nema potrebe za zamjenom. Međutim, s smanjenjem njihovog broja pojavljuje se vjerojatnost tzv. Elektrolitska korozija na motor i radijator automobila. Kao rezultat toga, zamjena rashladnog sredstva je bolje ne odgoditi.

Kako provjeriti antifriz

Rashladno sredstvo se izlije isključivo u pre-tkani sustav. Da biste provjerili antifriz, koriste se posebne trake za testiranje. Osim toga, vrijedi napomenuti da se neke antifriz varijacije prodaju u koncentriranom obliku. Prije ulijevanja takvog rashladnog sredstva, mora se otopiti pomoću destilirane vode.

Alati, uređaji, potrošni materijal

  1. Skup tipki.
  2. Set odvijač.
  3. Crijevo.
  4. Kapaciteta za 8-10 litara.
  5. Novi antifriz.
  6. Posebni alat za ispiranje sustava.

Ocijeđenje antifriza treba provesti u nedovoljnom mjestu za malu djecu, jer rashladno sredstvo je iznimno toksičan. Strogo je zabranjeno iscijediti u rezervoarima. Zamjena rashladnog sredstva provodi se na hladnom motoru.

Kako spojiti antifriz

  1. Možete odvoditi rashladno sredstvo pomoću odvodne dizalice, koja se nalazi na radijatoru, za koju odvrnite ispusni ventil do nekoliko revolucija.

  2. Kako bi se spriječilo da se antifriz radi na radilicama i drugim dijelovima tijela, crijevo treba povući na dizalicu.

  3. Pod odvodnom dizalicom zamjenjujemo spremnik za odvod rashladnog sredstva.

  4. Odvrnuli smo raka i odvodne antifriz.

  5. Da biste ubrzali odvod, možete ukloniti poklopac iz spremnika.

Kako ispirati sustav

  1. Kada cijeli rashladno sredstvo ispiremo sustav pomoću posebnog sredstva za ispiranje koje treba izlijevati u spremnik za proširenje.
  2. Onda donosimo jedinicu za napajanje i dopustimo mu da radi neko vrijeme dok se temperatura raste na radnik.

  3. U obveznom, uključite cijelu moć na štednjak tako da svi mjehurići zraka izađu iz sustava.
  4. Kada se motor zagrijava, treba se utapati i čekati dok se ne ohladi.
  5. Zatim iscijedite tekućinu za pranje.

  1. Otvorite spremnik za proširenje i nježno ulijte antifriz.
  2. Okrenite utikač.
  3. Uvjereni smo da nigdje nema curenja tekućine.
  4. Uključimo motor i pričekamo dok se ne zagrije na radnu temperaturu.
  5. Zatim isključite jedinicu za napajanje i pričekajte neko vrijeme dok se ne ohladi.
  6. Provjerite razinu tekućine i ispunite ga ako je potrebno.

Utrošeno rashladno sredstvo ne može se povući na otvaranje tla u kanalizaciju. Spremite antifriz fuzije trebaju biti samo zatvoreni spremnici. Do danas postoje specijalizirane tvrtke koje se bave raspolaganjem rashladnim sredstvom. Najbolja opcija će se pribjeći njihovoj pomoći.

  1. Alexander kaže:

    Još uvijek moramo znati što da učitamo IE Koju visokokvalitetnu antifriz. Na primjer, za moj lacetti, ja gorivo ohladiti premiju, za 4 godine nema problema. Kada sam napravio izbor za mene glavni kriterij bio je službena tolerancija od proizvođača automobila (Chevrolet), + je čista organska antifriza.

  2. Dmitry kaže:

    I osobno, bez razlike, što da sipam, koristim automobil 10 godina 20000km pomiješane sve proizvođače G12 i naše i nemoće ništa s antifrizom dolazi do 5 godina, a zatim nakon 5 godina samo zatamni i ide pod zamjenom. I sve preporuke tvornice gluposti
