Merc Racing Chargecooler install, coolant quantity required

[youngsyp]

Hi,

I'm going to install a Merc Racing chargecooler core in my 2013 S4 in the near future and just wanted to know how much coolant those who've done this bought for the job?

I've contemplated changing all the coolant whilst I'm doing the job, and believe the car holds around 12l of coolant with the stock chargecooler core. So might just buy a 20l drum and be done with it.

Cheers,

Paul
