Coolant Leak

Coolant leak.
This morning I had started my 1998 Ranger 4.0 to warm it up. I had noticed that im leaking coolant coming from the back of the motor somewhere. It looks like its a coolant line. It crosses acrossed the transmission from the passenger side. The hose has to be 1" in diameter it looks like. Its leaking onto my exhaust. Does anyone know what coolant line this is???

Welcome to this forum! Connect a cooling system pressure tester onto the system.

Lower thermostat housing is by far the most common failure in the 4.0L SOHC cooling system. Upgrade using non threaded sensors.
