Dear Forum,

Do not know whether it is a rule to create a topic per question but hopefully two in one topic is not a problem? I did some research on this forum and the web, but could not find satisfactory answers yet (or I did not look well enough :ROFLMAO: ).

The first question is more like "could this be a problem or is it a feature"? When I click on the window button for the window on driver's side (electric) it goes down but stops at around 1 to 1.5 inch before disappearing in the door. When clicking again, it fully opens. The same reaction is shown the way up. I click on the button, the windows goes up, stops at around 1.5 inch above doorpanel and when I push the button again, some two times, it goes all the way up and closes. Is this as it suppose to be or is the window not completely operational? The window does sound a bit as if it has some resistance but does move smoothly above that 1.5 inch.

The second question is a difficult one, because it regards sound, in this case a bubbling, like water flowing sound behind the heater panel in the dashboard. To be more precise, this sound popped up yesterday evening, once .... and today I could not reproduce a situation in which that sound could or should be heard.

Three weeks ago, the water pump, distribution and coolant is replaced (is that correct English by the way?) and driving on a multitude of different roads in those weeks the engine temperature kept steady as a solid rock. A few days ago I used the heater for the first time and no strange sounds were noticed. Yesterday, after a two mile drive suddenly I heard water flowing and when parking I heard a lot of bubbling behind the heaterpanel. Checking the foot trays everything was dry, no water, no fluid. The rest of the evening everything was okay and the Fiat brought us home safely, on a 90 mile trip.
Searching on the internet today I read stories about broken head gaskets so I got a little concerned. I once read that this type of engine can be sensitive for head gaskets problems, although I never experienced this kind of problems in my former Punto's myself. So I checked the level of coolant, but this reservoir is so unbelievably unreachable that even in the sun and using a flashlight I could not see the level of coolant. I opened the bottleneck and I saw a liquid, but not the G13 pink kind which should be in there. It seemed darker, but then, the position of that reservoir is also in a dark place. As the level seemed in that bottleneck it was at least above minus but not near max.
No water was found under the hood and it hasn't rain that much last week, so this can be ruled out as a cause.

Then I drove for an hour using the heater, small roads and highways and the heater is functioning fine and the engine temperature stayed between 85 and 90 degrees and no smell of smoke or burning underneath the bonnet, so this seems no problem. But what then was that watery, bubbling sound yesterday and why does the coolant color seem so dark?

Thanks for your reaction and kind regards,

Aad

Windows sound broken

@irc is you man for this problem

The water sound is air in the system

If the water pump was changed at a garage take it back

If you did the water pump did you open both bleed screws

Water pump was done by a garage. This evening when the sun was down, I saw the coolant, pink of color, so that should by okay. It was on minimum, so I think, but I am not a technician, that the garage forgot to bleed that second screw you mentioned?

Kind regards,

Aad

Yes or there's a slight leak sucking in air

At least you caught it before any damage was done

It will need topping up before any journeys or taking it back to the garage

Not all cars have a second bleed screw, cars with a seperate expansion bottle don't, but if the expansion is built into the radiator then it's often over looked

The one I got is like this:

Yep it this one that often gets forgotten

IT will self bleed through the one-way valve built into the thermostat, eventually

If you keep it topped up and undo the bleed screw on the heater matrix pipe occasionally

But seeing as the garage didn't do the job fully, you've already payed them, I'd get them to sort it for you
