Salut.

Am un Renault Mengane 4, 1.3 TCE, 116 CP, Business edition. L-am luat second hand recent.

Am remarcat ca dupa ce opresc motorul, vreo 2 minute ventilatorul de la radiator inca se invarte si apoi se opreste singur. Se intampla asta si dupa mers in oras, de vreo 15-30 minute, nu vorbesc de curse lungi.

E normal? Asa a fost proiectat Sa functioneze sau este ceva senzor defect?

Pe timp de vara, cand este cald, asa facea si a mea uneori. Iarna nu a facut niciodata.

E normal din cauza compartimentului motor mic al Meganului, nu prea a fost conceput bine pe partea de racire la unele motoare. La RS e cel mai rau ca porneste ventilatorul dupa fiecare oprire. Cel mai enervant este ca uneori declanseaza si alarma.

Sistem antipercolare, si la logan 1 pornea uneori cand era cald afara.

Salutare.Aceleasi probleme cu ventilatorul care merge dupa ce am oprit masina,le-am intampinat si eu.De obicei,de la drumuri lungi si forjata masina,asta am observat ca se intampla.Ceea ce dupa mine,este normal.Cred ca dupa depasirea temperaturii de 90 grade (se poate vedea pe bord),acest ventilator,montat intre motor si radiator, este comandat sa porneasca.Dar,de vreo 2 luni,am observat ca ventilatorul radiatorului functioneaza o perioada dupa oprire,chiar dupa o deplasare scurta in oras si ce este mai grav,functioneaza in mers prin oras sau in afara.Parca nici caldura in masinu nu prea facea fata.Pe carcasa ventilatorului,exista o rezistenta (rezistenta inseriata cu o siguranta termofuzibila),am demontat-o,curatat-o cu spray pentru contacte electrice,am masurat-o si are intre 1,5-3 ohm.Am spray-at si cei doi conectori la interior (conectori cu 2 si 4 pini ce se conecteaza pe ansamblul rezistentei).Am montat rezistenta si am remarcat faptul ca ventilatorul nu mai porneste de aiurea,am facut cativa KM si mi se pare ca este in regula.Oricum o sa o pun pe un tester si sa aflu si pareri de la reprezentanta.Rezistenta are codul 255508124R.

Doua fotografii ale acestei rezistente 255508124R (cooling fan resistor).

"The resistor is powered by the ignition and enables the cooling fan to run at slow speed. Once the engine reaches a manufacturer-predetermined temperature, a temperature switch indicates to the cooling fan resistor that the fan should run at high speed to draw more air through the radiator and provide extra cooling"
"The resistance should be low, less than 1 ohm, indicating that the windings are not open. A high resistance indicates an open winding and a faulty motor. Reconnect the fan blade to the motor shaft and turn on the power to the motor at the circuit breaker or fuse box. Listen for any strange noises coming from the motor".

La o vedere mai atenta,pe carcasa piesei este inscriptionata valoarea R=0.69 Ohm.Este posibil ca valoarea gasita de mine sa nu fie corecta pentru buna functionare a ventilatorului.Dupa ce o pun pe tester zilele astea,am sa va spun exact.

Am gasit si o schema electrica a acestui ansamblu cu rezistor de pe cadrul ventilatorului.
