Thanks Pete! Yea it was a little confusing trying to figure that out what if you look directly inside the expansion tank, you'll see a white bar smack dab in the center of the opening of the tank. That's the minimum level mark. So what you want to do is fill the expansion tank with coolant just right above that line. Run the engine with the heat on and any trapped air bubbles will work itself out. Get the engine up to running temp and check again to see where the level is but after it's all said and done, coolant level should be a little bit over the minimum bar.
Hey James! Not really, what tends to happen is they become brittle over time and allow the tank to move about due to engine vibration which can cause a leak at the reservoir tank expansion hose fittings. The car is 16 years old so imagine the number of times any of those rubber components have to deal with heat cycles within that engine bay, yikes!
About to change my expansion tank on e320 cdi while drunk lmao thank you for this
My shit is still leaking coolant lol
Where’s the leak???

Great video! What was the top off level in the expansion tank? I didn't see any markings on the tank itself.

I just bought one tang and when I check it something loose inside the yours have that
Nothing should be lose in there. I would drain the tank and see if you can find what’s loose inside
Yes
@@nelsonperez8619 Did you find out what it was!
Could be a float for the sensor. If the float goes too far down it triggers a magnetic switch to tell the car that coolant is "low"
Do those rubber grommets tend to leak over time?
