I got advices on Facebook and they told me that it's the Water Pump

So i checked on the forum and found that the Replacement part for the SRT-6 is this one:

Water Pump - SRT6 - three outlets.
Mercedes part#112 200 13 01

The cheapest one I found so far is this one ($181 + $75 of core charge) and its not even new, its rebuild

I have no idea how much a garage will charge for labor. But it seems that it will be at least a $500 total bill
