salut
astazi incercam sa identific pe unde pierd lichid de racire ; am pornit motorul si asteptam ;
am identificat ca nu porneste ventilatorul si creste nivelul apei in vas expansiune ; am facut un strap in mufa senzor de temperatura si a pornit ventilatorul ( probabil treapta a II a ) ;
nu reusesc sa imi dau seama daca senzorul este defect ( in bord indica '90 grade' constant, nu fluctueaza ) si nu porneste ventilatorul ;
am incercat sa identific prin postari ...am citit ceva de o rezistenta din corp radiator;
ma poate lumina si pe mine cineva; multumesc anticipat...

Cand ai facut bypass-ul ventilatorul a pornit direct pe treapta 2 full speed.
Ca sa functioneze normal schimba rezistenta din carcasa ventilatorului, vezi foto.
Exista in comert no-name pe la 50 lei care te tine 3-4 zile sau OEM vreo 200 lei.

Nici mie nu-mi funcționa rezistenta într-o zi si am descoperit ca era puțin dezlipit un contact. S-a rezolvat cu niste cositor.

Se mai poate duce siguranta termica - bucatica aceea mica de sub rezistenta verde.
Eu am una no name de 50 lei pe masina de 1 an si inca rezista.
Luata de la Autoeco pentru radiator Stilo.

am desfacut rezistenta ; nu arata bine dar am masurat-o si are o,4 ohm ( pe ea scrie 0,3 ) ; am incalzit-o cu un generator de aer cald si ...nimic ! am verificat circuitul ( de la releu pana la rezistenta ) sigurante, relee ( tr.I si tr.II )...rezistenta termica nu am desfacut-o ...

????????????????????????????



Daca aici ai 0.4 ohmi atunci rezistenta este buna.
Ai de verificat releul si siguranta care vine in serie cu ea.

Mda...am masurat rezistenta infasurarii dar nu l-am cuplat la tensiune sa verific contactele...daca nu...merg in amonte...era interesant care e totusi valoarea rezistentei...
Multumesc

Nu mai posta consecutiv. Te rog, foloseste butonul de edit, ca discutiile sa fie mai usor de urmarit! O postare poate fi editata timp de 30 de minute, de cand a fost scrisa!

Am cumparat si eu un releu in acelasi tip de ambalaj ,daca ma iau dupa etichete este facut in Turcia, pare la fel cu releul meu de 166 2.0TS , la mine cand ajunge la 98,4 grade porneste prima treapta a ventilatorului dupa radiator si la 93 se opreste ,presupun că comanda sa porneasca la 98,4 ,o da calculaorul masinii ,nu stiu daca releul stie sa porneasca /opreasca ventilatorul la o anumita temperatura.
