coperfild · Answer

Check how the knob works - warm, cold, the cable has definitely burnt out

Bobot1994 · Answer

The knob normally walks when I make it cold and it blows hard and when it comes to heat it is free but cold air Added after 10 [hours] 26 [minutes]: Someone had such a problem

migmig85 · Answer

As the temperature rises, the radiator fan will turn on? And do the radiator rubber hoses swell or are they still soft after heating?

Bobot1994 · Answer

The fan does not turn on slowly. Upper radiator hose hot bottom cold. Wires swell hoses from the heater are hot when I opened it, the air flies only hot, the radiator is half warm but sometimes the engine temperature is cold 90/100 degrees please help. Oze be the heater's fault because I don't know whether to undress. Thanks in advance

migmig85 · Answer

head gasket, thermostat or stony heater

Bobot1994 · Answer

I replaced the thermostat with a new one and the heater may be because if you unscrew the cap the radiator gets warm and when it turns cold

migmig85 · Answer

The head gasket after heating creates an airbag in the cooling system and automatically aerates the system then the cables swell and the radiator fan does not start.

Bobot1994 · Answer

But the oil is at a level and how can you check if it's Head Gasket you need to give heads for planning Added after 1 [minutes]: So it's not worth warming up the heater

migmig85 · Answer

Yes, but a bit of compression gets into the cooling system and has the same effect as you do. Planning and checking for minimum tightness + new head bolts is best.

Bobot1994 · Answer

And the cost is not better new engine because the mechanic said that it is like a heater the more that when I turned it on pieces of something flew out

Added after 4 [minutes]:

And the wires do not swell because the heater is clogged, it can also be from this

migmig85 · Answer

No, because after such a repair, peace of mind and you know what you have the cost of complete regeneration of the head is about 1500-2000 PLN, if you do not need to replace, for example, timing, then you know the costs are rising.
And when buying an engine, we do not know in what condition it is bought and whether in a year there will be the same history.
The engine spacer also costs about PLN 1000, surely oils, fluid and timing to be replaced on a good day, besides you have to buy this good engine

Bobot1994 · Answer

Oh damn, it's nice now I don't know what to do and how would I try to find a place where the air escapes and I would lubricate with silicone

migmig85 · Answer

it can't be done because such things happen on the plane and you won't do anything with silicone

Bobot1994 · Answer

Ahaj, it is hard to know what I will do now, and matches can be closed from the heater

migmig85 · Answer

Buy a buddy co2 head gasket leak tester and maybe I will show you something more.

Bobot1994 · Answer

And I had to add that the suction corrector at the bottom is slightly warm. Added after 13 [minutes]: And he should be hot, I think

darek.jacek · Answer

Dude, don't be ridiculous. A car from 1995 and you write a typical text for a poor man, you know what you have. It is more profitable to buy another crispbread and sell it instead of invest. It is not known what the reason is and you urge you to exchange upg.

Hello
I have had an Audi a4 b5 1.9 tdi 1995 for a week.
I also have a problem with heating, namely warm air flies on the glass and cold air flies into the middle.
Both hoses from the heater are warm.
What could be the reason for this?

Anonymous · Answer

Slippers like Swiss cheese. You need to remove the fuser assembly and put a new sponge on the flaps.

michal8819 · Answer

Heater assembly? Tz? What's the best way to go about it? I have to disassemble the entire board?

Anonymous · Answer

Well not otherwise .. Here is a video showing flaps without sponges because they have already flown 100% are the metal flaps with holes .. For regeneration, I use a sponge to leak audio 3-4mm thick with glue.

michal8819 · Answer

I was afraid of this, so a lot of fun awaits me.
Now I'm on my way and, in fact, the heat is so strong on the glass.
All in all, if I were to disassemble it, it would probably be better to replace the heaters to be sure.

What else should you pay attention to, possibly?

Added after 11 [minutes]:

Still, such an observation, when I take the air to the maximum, feel it warm, and if on the 3-4th line, it is somehow cold.

Strumien swiadomosci swia · Answer

It's normal, replace the heaters to be sure and these sponges, I use cardboard for sticking.

michal8819 · Answer

I will do so for this moment, thanks a lot.

michal8819 · Answer

Hello
So far, I've tried to clean the heaters, I bought a cleaning agent, connected the pump to the heater wires and cleaned the heaters on a short circuit, but there was no dirt or anything like that and I didn't notice that it flew poorly.
I noticed an old sponge on the center panel.
And now I don't know because it's still cold and slightly warm on the glass.
Getting ready to dismantle and replace the heater?

Anonymous · Answer

Replacing the heater and regenerating the circulation control flaps is a standard job

michal8819 · Answer

Thanks for the quick reply. But when I think about how much undressing it is, it gives me goosebumps. But nothing will pass anyway.

michal8819 · Answer

Hello everyone
I started replacing the heater core.
The board has already been dismantled but I have a small problem with the metal beam because it also needs to be unscrewed but I can't really see which screws to unscrew.

Ireneo · Answer

On the shaft from the engine side, the big ones you see, the column and one from the pedal bracket. And for stubborn 2 screws under the ecu.
