Change Antifreeze on Esprit S4

Yes it is! There are plenty of guides around the forum on how to do it - and your S4 is even easier since it's one circuit.


First, go out and buy a can or two of coolant flush from your local auto shop - this will clean up any deposits that are in the system. Follow the instructions on the can and afterwards drain the radiator.


It's helpful to have the back end of the car jacked up higher than the front - both with regards to getting the old coolant out but also for removing air pockets when filling with new coolant mixture.


The whole procedure is also well documented in the service handbook. No trouble at all to perform - with the exception of replacing the radiator plug, something I found a pain in the ass to do on my Turbo SE :)
