Default Pressure test

So I loaned a pressure tester finally and hooked it up and sett it to 15 psi. It held right at 15psi. Should I set it higher? There does not seem to be any leaks anywhere and the one by the water pump just is a really slow drip. Is there anything else I can look for to make sure it is just this small leak. If this is the case I am going to get the water pump, gasket and 180 stat. Please let me know if you guys think this is the right move. Thanks!

No do NOT pump it up higher, to much pressure and you will cause leaks.
The bearing on the water pump leaks because the seal has dried out/worn out.
Its not going to leak under pressure, its going to leak just because its submerged and coolant is seeping past the seal.
Just replace the water pump and all coolant.

Another thing on the leaky water pump, they can begin to wobble, you'll see the pully wobble when running. Inside the pump spaces are tight, so when it wobbles it eats aluminum. One on left is old and wobbled, also show previous owner love of stopz leakz, and tap water instead of distilled.

So I got everything apart and getting the gasket off this afternoon. What kind of antifreeze is in this thing. It says OAT on the cap and it looks pink or orange. Is it dexcool? I am going to get it flushed. Should I keep it OAT or Dexcool or go with regular stuff?
Thanks!

flush, flush, flush, and reverse flush the heater core, go back with green premix 50/50 antifreeze like Peak. Dexcool is no friend to Rovers. It changes chemistry with air or other coolant contamination and will become dexmud and can also attack certain materials in the cooling system, including the coolant cap itself.

Sure I have, actually the TC is on all the time unless you turn it off.
