Please need help coolant leak
I have a 2006 jeep wrangled unlimited with the 4.0. I just bought the jeep n after a 2 hour drive home. When I got him it was steaming out of rad cap over flow hose connect. It didn't have a over flow hose or tank when I bought it. Do I replaced the cap. Thermostat and the houseing. So as I put all new. Coolant in. And about to start it. It start leaking from bottom pulpy below water pump. Do I rigged wheep hole was it. Do changed water pump. Used water thread sealant and it still leaks. What could it be??
