Hello everyone
Yesterday I was in the motorway and after a quick stop, I noticed some steam coming out from the engine bay. When I opened I saw this:
After inspecting the area it seems the problem was coolant being spilled from pressure tank cap.
Some facts:
- My radiator fan is fully working
- Just some moments before I overtook a car and I rev it up a bit to a range of +/- 5000rpm
- I did not overfill the coolant beyond the "MAX" mark in the coolant reservoir.
- After this incident, the coolant level naturally decreased but not too much. I could still see coolant in the reservoir but it was below "MIN". I was afraid to open the cap with the engine hot.
- Right after checking this, and while entering back to the motorway I feel a clear loss of power until I foot down the accelerator and suddenly everything got back to normal.
- I used the IKE diagnostic to check the temperature of the engine and it appears normal ( between 90 and 95ºC)
- The entire trip (224 Miles) the car did not lose more coolant.
My questions:
My first suspect is the pressure tank cap. There is any common fault known with them?
Could this situation also indicate a problem with the thermostat housing?
Any comment/help would be very appreciated
