Hi everyone.
I want to first apologize if this thread is not where it should be. I'm having an issue with my Mk6 GTI that I got just two or three weeks ago. I bought the car off an auction and had it shipped to my country. After all due paperwork I've only been driving it for the past two weeks and have barely drove around 800 miles on it. Car currently has 90,500 miles and is completely stock.
Now the problem goes as follows: yesterday I got the Stop check coolant message. I pulled over and noticed my expansion tank was almost completely dry. Poured some coolant mix onto the reservoir after letting the car cool down for 40 min or so and drove off. Not even 10 min later I get the same message again and when I checked the reservoir was empty again. I had a class to go to so the car was parked for almost 2hrs. After that I poured some more coolant in and headed home (roughly 5 miles away) and when i got here the reservoir was dry. Upon inspection I noticed my water pump had a minor leak so I thought great I'll have to replace my pump. Didn't use the car for the rest of the day.
However, this mornIng I checked and my expansion tank was completely full. What the hell? Where did that coolant come from? I decide to turn the car on to see what happens to that coolant with the engine on.
For as long as the car is warming up coolant level is normal (guessing because the thermostat is closed). However, once the engine reaches normal operating temperature (190°) I noticed coolant began to be pulled from the reservoir quite rapidly. As this happened my engine temperature dropped a about half just as the Check coolant message popped up again and the reservoir became dry again. The radiator fan didn't turn on at any point. No leaks at this point since I shut it off immediately.
So I'm not sure what is happening here. Could air be trapped inside the system? I didn't mess with anything in the system in the days prior so I don't see how this could happen. Also, shouldn't the radiator fan turn on once the engine reaches operating temperature?
I tried to "bleed" the system by removing the cap, turning the car on and pressing on the rad hose that attaches right behind the throttle body. For a min it seemed to work as there were burping sounds coming out the expansion tank and some coolant showed up. But is soon stopped and the coolant was sucked back in.
Any help would be appreciated. Remember this is a salvage car so dealership is not an option.
