Ce radiator sa pun?

Ma speriasem, daca e pe program atunci e bine. Ca sa nu fie rau.

 

 

For the record: cei doi senzori pentru motorul in cauza.

Coolant-temperature sensor

The coolant-temperature sensor is screwed into the cylinder head and registers the temperature of the coolant by means of its variable resistor (NTC= negative temperature coefficient).

Among other things, the coolant temperature serves as a measured variable for the following functions:

 

  • Start volume calculation
  • Injection volume calculation
  • Nominal idle speed

In the event of the coolant-temperature sensor failing, a fault code is entered in the DME control unit and a substitute value is calculated from the value of the intake air temperature sensor with the aid of a temperature model.

 

 

Coolant Temperature Sensor at Radiator Outlet

This temperature sensor is fitted in the outlet hose of the radiator and registers the coolant temperature after it flows out of the radiator.

The coolant temperature at the radiator outlet serves the purpose of driving the electric fan

 

 

La E46 M3 exista chiar 3 senzori (2 in aceeasi carcasa si care fac ce zici tu, pacat totusi ca vorbim despre alt film):

The housing of the coolant temperature sensor contains two sensors (double temperature sensor). The one sensor sends the signal to the DME control unit while the other sensor is connected to the instrument cluster.

Am comandat termostatul. Osa vina zilele astea.

 

Problema este ca am mai mers cu masina. AM mers pana la carrefour militari,acul la apa a ajuns la rosu aproape si ventilatorul acela nu a pornit,neam.

 

Am tras...din nou pe dreapta am astepatat sa se mai raceasca un pic.

 

Acum cateva zile cand sa manifestat chestia asta prima oara,cand acul ajungea aproape de rosu sau pe rosu (ca nu pleca mereu la fel) pleca ventilatorul la un moment dat( daca ajungea pe rosu si opream masina ventilatorul pleca oricum).

 

Acum ,pe drumul spre militari, a ajuns acul pe rosu si ventilatorul nu a plecat deloc. E semn rau asta banuiesc,a evoluat problema in mai rau.

 

Sper sa se rezolve problema odata cu schimbul termostatului.

Am schimbat termostatul acum o ora la service.

 

Am vazut termostatul vechi cum arata. Era jalnic...si blocat pe inchis. Plin de un fel de mazga ..ceva galben asa.

 

Dupa ce l-am pus pe cel nou ( behr -165 ron) am lasat masina sa mearga la relanti mai mult timp sa vad daca mai creste nivelul la apa.

 

Nu a schitat nimic...sta cuminte acolo pe la 90. Am mers mai tare cu ea,turatii mai mari o bucata de drum sa vad daca mai sare de 90 ,e constanta temp la apa.

 

Sper sa nu mai am vreo surpriza pe viitor.

bravo, daca ascultai de la inceput nu chinuiai motorul atat

 

 

Corect.

 

Acuma a aparut altceva: cand e motorul rece,dimineatza relantiul sta normal pe la 850-900 turatii, iar cand motorul se incalzeste,dupa ce merg putin cu ea,relantiul este cam ridicat,sta pe la 1000 turatii.

 

Care-i cauza??

 

Poate avea legatura cu faptul ca ajuns de vreo 2-3 ori acul pe rosu..sa-i fi influentat in vreun fel ralantiul asta??
