Thanks all,
I will not drive the car anymore, I will tow it to the garage
About the price of the WaterPump I found this one on CARID
Cardone® 55-83333 - Engine Water Pump
Which is the Cardone New (not rebuild) #55-83333, it's only 124$ which is very surprising.
or here
$130
Do you think it's the good fit ? It seems to be the good one for the SRT-6
