    Why? Do you think the water is coming out of the cap? Is the cap faulty?

    So i followed the hard pipe towards the matrix hoses, and i found this U-Clip..removed it and saw pieces was gone from the housing....can air be sucked in and cause the overflow ?


    And a picture och expansion tank...

    What do you mean block all of this ? If something wouldnt seal tight you would be dripping coolant too.

    One other thing, the temperature take about 15min at idle to even starts to move at all.
    When it comes up to 90, it stays there so probably its working and prevent overheating.

    Its a new thermostat and no leakage.

    Can the new thermostat be faulty ? since the temperature takes ages to show on the gauges.

    I've found our cars take awhile to warm up, especially just idling. 15 Minutes idling doesn't seem unreasonable.

    If replaced your thermostat recently then its most likely good (Yes a new thermostat can fail or be faulty out of the box though, which is why its nice to put it in some boiling water first to see if it works).
    If your car comes up to temp 90C and stays there while driving in cold weather (<40 degree Fahrenheit) then it should not be your thermostat. If it comes up to 90C while idling and then your gauge goes down while driving you have a bad thermostat that's stuck open or failing to close properly

    You can also use the secret climate control menu by hitting the up fan direction and the recirculation Button at the same time. This will display a 1C on your climate control. Use the up and down temperature buttons to go to 49C and then hit the recirculation button to select 49C. This will tell you your actual coolant temperature.

    I just measured my Coolant Temperature Sensor.
    Cold = 2,8kOhm (should be around 2kOhm at 20C Celsius)
    Warm = 1,4kOhm (should be 200Ohm-300Ohm at 80-90C)

    I think i must change it :P

    Update again, i changed the Coolant Temperature Sensor and the Coolant Flange. The change went well and i filled up with coolant and started again.
    It took about 5-10 mins and it was up to 90C, but no hot air.
    Opened the matrix hose and bled the system. Sill no heat, i think its more air inside.

    And upper/lower radiator hoses are about 35C.

    After a while the gauge was about 110C, but 85 with a lasertemp at the tempsensor hose ?!

    Okay so you've changed,

    Thermostat,
    CTS,
    Coolant Flange.

    Engine gets up to 90C while idle, and stays 90C while driving? Or is it still showing 110C after awhile. 110C is way too hot....
    What does the climate control menu say 49C (See my previous post about how to do it) when the car is fully warmed up

    Bleed bleed bleed. You've opened the system in many different places now. Make sure ALL of the air is out. This can take many different methods to accomplish over a couple days. Have you ONLY bled from the heater core hole? On the 2.8 There is an allen bolt bleed spot on the front of the engine... Not sure about the 1.8. Bleed from all of the different places the 1.8 allows you to do so.

    Is the car still bubbling and spitting coolant out the overflow hole of the expansion tank?

    Is the system getting pressurized? Do you hear any gurgling from the heater core when reving the engine and taking your foot off the gas?

    Hi Ryanic, when the car is idle i got 90C+ after maybe 5-10 mins.


    I think i have an bleed spot on the hardpipe, and one beside the coolant temperature sensor.

    I think i have heard small gurgling from the heatercore the other day when i switched from HI to LO.
    I have removed the glove compartment just now and looked at the flaps, it seems ok the arms are moving.

    Todo tomorrow:
    *Check the Climate Control menu.
    *Bleed, bleed, bleed.

    Thanks again.

    So i have idle the car and went into the menu 49C, its a little slower than the gauge...i turned it off when the 49C read 100C, strange part is that i dont have none of the 2 hoses into/from the heater core hot now...i did not had the time to bled today.

    It must be more air ?

    One other thing. When it was 100c and turn the car off, I have about 75-80c after 2minutes. ..

    No, for the labor..they had to change some rounded torx screws, 1 vaccum hose, change of expansion tank and the waterpump.

    The waterpump (SKF with metal shovel) costs 30 from Germany
    Expansiontank costs 5

    Shouldve done it youself, changing the waterpump is not a big deal :P specially on 058 blocks.
