Correct temperature pont that fans start running? Chrysler Sebring 2006 2.7V
Thank you to read this:
The problem has post here, some improve but it's always problem:
Issue:
1) the coolant boiling,
2) difficult start engine when the warm car not cool enough
What I have done:
1 change coolant more than two times
2 change blood housing(Thermostat housing) two times
3 change Thermostat two times
4 flush coolant system one times
5 mechanic checked, it is not head gasket problem, fan running well
I just knew there is two temperature sensors in this car, first one in the
Thermostat housing, and it control the fan start and the water temperature
gauge; The second close the thermostat at the bottom of engine, it send
the data to OBD
I record the OBD Engine Coolant temperature when I drive in a traffic jam
today
1) running in city first 10 minutes, 50°C~80°C
2) about 5 minutes idle engine in traffic jam, 106°C, the fan begin work, the
temperature back to 96°C, the fan stop
3) continue slowly drive, 104°C, the fan start again, the temperature back
to 94°C
4) skip the traffic jam, running in 40-60KMH, 5-10 minutes, the temperature
got 108,109°C not fall down, stop car, the fan run fast, but the temperature
not go back, the pipe of out radiator is warm but only about 35°C
5) stop engine for 5 minutes, start engine again, it difficult to start, and after
starting, the engine is shock in first 1 minute, the temperature is 107°C,
continue running, it got 114°C, when it was in 110°C, I can here the coolant
boiling again, open the car fully hot heating wind in 4 speed, the
temperature fall down to 104°C, this running time is about 7 minutes
6) stop car, keep engine running, turn off hot heating wind, the temperature
slowly move to 107°C, under the 110°C, the coolant doesn't boiling, turn off
engine
that's the problem about my Sebring, from temperature gauge, everything
is ok like it was good in one year ago, who can give some idea?
Every mechanic said different answer, I have tow choice to do, or both of
them:
1) change water pump, the possible reason, it running weak, so the pipe go
out from radiator is too lower(about 35°C when the pipe go in radiator is
95°C)
2) change the fan control module, I don't know the real name, it mean it get
data from temperature sensor and control the fan start or stop, the possible
reason it start delay(today it start in 104~106°C
Thanks for every answer, blessing from The highest~
