As in the title guys found a coolant leak recently not massive but over the course of 6 8 weeks it drops from max to just below min also found water on the undertray when i removed it earlier this week.



Audi a4 coolant leak back of engine. Coolant leak at the back of engine at the top audi 2002 a4 question. Friends 2005 audi a4 18 turbo has a coolant leak friends 2005 audi a4 18. This is my first video sorry for all the shaking and boogers.



You can not see it directly. Coolant leak in rear of engine. The only triple square on this engine is the fuel line to coolant line bolt.



Allergies were acting up and i was so drugged up with allergy medicine. The coolant that is already in the pipe on its way back to the expansion tank will drain back out but you shouldnt lose any more i dont think. If you do it when the engine is cold then you wouldnt have to drain the coolant as the pipe sits above the system.



Everything else is t 30 10mm 13mm 16mm and allen 6. This picture shows a screwdriver wrapped in blue tape pointing at the item the bottom of which is leaking. I captured it with my smartphone.



Everything else is t 30 10mm 13mm 16mm and allen 6. Ive replaced the coolant reservoir and the cap. Doing the rear coolant flange isnt terribly hard.



The video above shows you where the coolant reservoir hoses and connections on your 2002 a4 quattro base are located and the steps needed to fix minor leaks. In the last 30k miles ive replaced the timing beltwater pump system the clutch the heater core. Engine coolant which is also called antifreeze or anti freeze moves through the inside of your a4 quattros engine and keeps it from overheating.



Have done some research and found it could possibly be comig from the coolant flange as from what i can see the previous owner has put some sort of plastic glue to hold it together likely from a previous leak. I have an engine coolant leak on my audi a4 avant quattro. In the last 30k miles.
