Newbie with R53, need help determining water pump or thermostat leak.
Hey guys, we've go an 02 MCS that I recently replaced the coolant tank after it exploded. I refilled it with Peak 50/50 gold colored coolant, maybe should have used Zerex? Immediately after and unseemingly unrelated, a coolant leak started in the front of the engine compartment.
It occurs if the engine is started for just a minute. The attached picture shows were it leaks without the front tray attached. It's quite baffling b/c I cannot see the sources. Could this be the water pump or the the thermostat?

The pic shows the leak is front right...
Thermostat leak is usually a weap....nobdrip.... Look around...could even be a hose or the radiator...gotta look...YOU are the detective here....
Drips can hit splash guards and travel....so WHERE it lands is usually not an indication of where it might come from....

I've tried, it seems to come from the front of the engine somewhere where I can't see. It does not appear to be from the radiator area.
I was hoping to pressure test it, but cannot find a suitable adapter.
A water pump would not leak this much I'm thinking. I'll get the thermostat & gasket and see what I find.
Thanks guys!

go to the local discount tool store. buy a cooling system pressure tester. read the instructions on which adapter cap to use. pump up the system to 16psi and watch for the leak. It's a far more accurate way than guessing and if it is the water pump, that's a very time consuming job (remove supercharger). I had to do this testing the week after I picked up my 06 R53. It needed a thermostat gasket. no big deal.

Are you saying the Harbor Freight kit does work with the mini coolant tank?
