    Hello, I have a problem in my recently purchased seicento 900. It doesn't heat very well when I start it, it doesn't heat anything but when I drive at high speed, it heats on average as soon as I stand on the traffic light or in the traffic jam there is no heating. I have already replaced the thermostat and heater and still

    And the heater valve? OK? opens the flow?

    Yes, I vented several times as recommended, but still nothing that suggests that it may be a water pump that is weak and can not pump at low speed I don't know what it can be

    Heater I bought a new one with a new valve

    Well, because you write as if the pump pumped poorly.
    Is enough hot liquid flowing into the heater? There is no plug in its power supply?

    when the heating works like a jade and I have the airflow set on the first line, it heats up when switching to a larger heating blanket, the heating sits down

    Cover the radiator. Safety cover is not foreseen in Safety Deposit Box. CC900 has this cover provided and is assumed for the winter period after removing the front license plate, installing the aperture and re-mounting the plate, and for me this cover installed in the bumper is covered with half of the air inlet on the radiator. I made my CC900 by installing the pointer temperature indicator and in winter, after covering the radiator, the temperature of the coolant in the radiator during driving remains at 80 degrees

    So put the cardboard on the radiator in the front?

    Check if you have a functional thermostat because if it is damaged (open permanently or only permanently ajar) it causes not only poor heating but also the engine is not heated which is not healthy for it. The radiator cover (when the thermostat is damaged) is a half-measure and guerilla

    I set up a new thermostat

    I understand, but check it out, you may have hit the sell. How it's working is just a cover.

    Eh, really with this veil?
    Someone recently asked "how do you know what the real temperature of the engine is?"
    @ERESZEK CAUTION with this

    And did I not understand something?
    At a standstill, it doesn't heat, but when driving? This cardboard box for a Christmas tree?

    Well, I do not know what the cardboard is for, since when I go it heats up that if I give more power to the heating, the heating disappears, if I switch to a smaller airflow force, the heating comes back crazy with no heat. The heating does not work at a standstill.

    There should be adequate pressure in the cooling system for the fluid to circulate quickly enough. You may have a leaking plug or reduced coolant pump performance.

    that is, replace the cap from the expansion tank and how can it not water pump?

    Cork is a cheaper version and faster. Someday babol just has to be pity to replace it one after another because half the car can be replaced.

Topic summary

The discussion revolves around a heating issue in a Fiat Seicento 900, where the heating system fails to operate effectively at low speeds or when idling, despite the replacement of the thermostat and heater. Participants suggest checking the venting of the system, the functionality of the heater valve, and the performance of the water pump. Concerns are raised about the coolant circulation and pressure in the system, with recommendations to cover the radiator for improved heating during winter. The author confirms the installation of a new thermostat and heater but continues to experience heating problems, particularly when increasing airflow. The conversation highlights the importance of ensuring adequate pressure in the cooling system and the potential need for further diagnostics on the water pump and expansion tank cap.
