I have a reoccurring problem and I pretty desperate by now.
I have the Puma 1.6 2001.
The problem is that on dashboard it seems that the water temperature is skyrocketing into the red zone after a few kilometers, then it drops a little then settles in the end point after the red zone.
In one of these cases I opened the bonnet and checked a few things:
- The fan next to the radiator was working on the 2nd level and blowing cool air from it.
- I opened the water tank and a little steam came but nothing else. (As I know if the coolant was boiling then it should come out as soon as I open the the water tank)
- Checked the temperature with an obd2 reader and Forscan and it showed me that the temperature is around 140 Celsius. (As I know it's not possible to have this high temperature)
- If I stop the car for five minutes then restart it, the temperature spike stops at the middle and starts to rise again after a few minutes.
I already replaced the following parts:
- Water temperature sensor
- Thermostat
- The cover of the coolant tank
- The radiator is checked and it's in good condition
- The pipes are checked, I have no leak
- The coolant level is at the max, I don't need to fill it.
Edit.:
I forgot to mention the fact that it doesn't matter if i turn on the heating or not, the results are the same.
The other thing is if i turn on the heat in the early stage of the "overheating" the air it blows into the interior is not warm, so i assume the engine is not warm too.
Sorry for my English I try my best,
Thank you for your help in advance.
