so i decide to take a look at my engine today and i see that what i think is the engine coolant (red liquid) in the plastic thing above and to the right of the engine cover is not full. I dont know how long its been like that, am i doing damage to the car? its Right under the minimum line. Where do i buy this stuff and how do i mix it etc

Sorry for being a complete idiot

According to my Blauparts kit from when I replaced the timing belt. You could check with your local parts or google it.

OEM & German mfg. Audi Pentosin anti-freeze 2 to 5 liters (anti-phosphate/amine)

If the fluid was too low, an error light should have gone on in the dash.

deffinately go to VW or Audi dealership and get the r-12 pink coolant. you wont find it at autoshop stores cause VW/Audi dont sell the formula....

i've heard that this stuff will gel up if you mix other formulas... not sure if it will, but I wouldnt risk it for basically the same price. (pre-mixed Prestone stuff = $11for 1 gallon, Audi= $23, and youget 2 gallons out of it after you mix it, making it the same price)

you have to mix it 50-50 with water though.
