Changed the oil, and my water pump was leaking coolant. I changed the pump, hoses, belts and all that about 15k miles ago. But when I changed it, the pump wasn't bad, just the gaskets. So I assumed same thing this time.
Pulled the pump, cleaned it all, new gaskets and tried rtv on the gaskets this time. Still freaking leaking! And it's not the pump.... not sure but coming from the passenger side Where the pump bolts up
