Technical Smells like exhaust :(

[dave]

do puntos have taps on the heater or is it constant heat, and the air redirected upon the temperature setting?

constant, has flaps no cock

Sounds like a tiny leak in heater matrix.

Is it something that is dangerus in any way.
I've read about changing the matrix, and it sounds like a very difficult and hard thing to do. Something that should be done at a warm summer day

What about that stuff one can add in the cooler liquid. Some kind of powder to seal small leaks?

Yes, some rad sealant will do.

There is no sweet smell in the cabin but I can always smell petrol when i first get into the car...

Yes, some rad sealant will do.

What???

old skool cure for a leaky rad. the radiator sealant is probaby a better idea

 

[hjalte81]

Ah ok.. Så the radiant sealant is a kind of powder, to mix with the coolant right?
Cant find any. Maybe if some of you had some brands to look for?

Radweld, Halfords will have it. liquid you just add to the coolant.

Found this: http://www.thansen.dk/product.asp?c=1948315976&n=-2027216146&pn=-2027216025

It's from a danish spareparts firm.

The brand is valvoline.
This is liquid. Where should I add it? If you look at my attached pictures in previous reply, (the one where I point), is this the place?

And one more ?, what if there is NO holes in the cooling system. Will it cause a clock somewhere?

Thanks so far...

should do the job.
usually tells you to add direct to the rad on the bottle but expansion tank (as in your pointy photo) is usually the only option, won't do any harm if there is no leak, just circulates until it hits a leak or you change the coolant.
