Can't bleed coolant system on Audi A3!

Please help- - how do I bleed the coolamt system on a 1997 8L Audi A3 1.6 engine? (same as 1.6 Golf ofsame vintage I believe) I've replaced the head gasket, replaced the coolant but now I have an air lock in the system and can't find a bleed valve/nipple anywhere to bleed the system through. I can't pump the air out by hand by squeezing the rad pipes, and there's no cap on the radiator. Anyone any ideas as to how I can bleed the coolant system through?This would be a huge help, and greatly appreciated. Thanks, Andy. (not a 2005 model)

In my experience with Audis, after any job requiring changing/draining the coolant the car ideally needs to be driven. With the coolant topped up to max drive the car, keep the revs up and shake the car with steering and over bumps where possible. Whatever you do make sure you take at least 2 litres of water/coolant with you, as as soon as the air lock goes, the level drops a lot and quickly. Also keep an eye on the temp gauge and avoid letting it go much over 90 degrees (over 90 on the gauge usually means its well into the hundreds) When you get consistant hot air through the heater, at idle, the level should of settled. If this doesnt work you may have thermostat issues or a blockage. Good luck, let me know how you get on.

I think if you leave the cap off of the small tank(where you add water and antifreeze to) and then run the engine for a while with the cap off , you should be able to get the air out this way.

YOU WILL NEED TO GET THE CAR UPTO RUNNING TEMPERATURE SO THE THERMOSTAT STARTS OPENING AND CLOSING.!!!! THE AIR WILL BE PUSHED INTO THE COOLANT EXPANSION TANK...REMENBER TO TOP UP THE COOLANT AFTER THIS...OR YOU COULD DRIVE THE CAR ROUND THE BLOCK THIS WILL ALSO PUSH THE AIR OUT OF YOUR COOLANT PIPES ( GET SOME HEAT INTO THE ENGINE TO GET THAN THERMOSTAT OPENING)

Where can you find the radiator cap in a volkswagon bora v5


Janet, top up your coolant in the coolant reservoir/expansion tank it is the rounded bottle closer to the shock tower.. Remove Blue or Black cap when engine cold and top up, run engine till warm and recheck after cool and top up again if necessary. Make sure to have leak repaired sooner then later to prevent future costly repair.
Check the attached links,instruction and guides, Good luck

My car is overheating and the heater is not working. I've been told it's a blown head gasket. I've also been told that I need to bleed my cooling system. So my question is, where is the co


If you have a blown head gasket, surely you will overheat because some hot combustion gases are entering your cooling system. No way you can remedy it by bleeding the system. Bleeding the system is just removing the trapped air in it. Running the engine with out the radiator cap will do the trick.

Audi a4 1.8t random miss fire


Check out the AboutAutomobile.com site for NHTSA complaints. I believe there was a defect in the cylinder heads for this engine. The redesigned heads have a different suffix letter than the stock heads.

For a time, the Manufactuer was paying for the repair.

Hi, i've been told the turbo on my 2006 !.8 Golf TDI has blown and need a new one. How much would a new one cost please? Thanks


Best place to start is eBay vw turbos can range from $250.00 to $700.00 but it depends on your model and engine size. You can look up vw golf websites and I believe you can even by them cheaper through club web sites

I have a 1996 Subaru Legacy with a 2.5l engine...it has been overheating randomly and I thought that the thermostat was starting to hang up. When I looked in the overflow bottle there was an oily substance...


Ok, there might be just one issue or a couple. Head gasket or cracked head or engine block, usually though if it was this the coolant would be in oil. Please try to answer each of these questions, are you losing coolant? Do you know how to bleed the cooling system? If this is a automatic, check the trans. fluid level, you may have a trans. cooler leak inside the radiator. Did you replace the thermostat, it is at the end of the bottom hose and easy and cheap to do. Make sure you bleed the system if you do this. If you do not know how to bleed it, get back to me and I will walk you through it. And by the way if the trans fluid is cloudy looking, then there may be water in it from the radiator. Ok, get back to me when you can, thanks, Andy

I have an audi 97 a4 6 sylander and i had to change the metal pipe wich transfer water from reservor to termostat housing do i need to bleed the system after fix and soo wher is the bleeding valve thanks...


you dont have to bleed the water it automatically takes out the air when it runs and the thermostat valve opens check the level again after a run of 5 miles or when the temp is in the middle

remember not to check when the engine is hot

Audi a6 2.8e keeps over heating the fan on the first speed does not come in.The water is pushing out the cap.Did replace the water pump,pressure cap,fan switch,bleed the system no air in system


Sounds as if the cylider head gasket may have blown. If the engine oil has changed to a grey colour, thats the problem. Even if the oil hasn't changed I'd suggest a cylinder compression test fromyour friendly motor machanic
