Head gasket could be bad
The heater core or connecting hose is broken.
Probably a blown or leaking head gasket.
Antifreeze? Water pump?
i believe you can put the antifreeze anywhere in a jeep
That is most likely antifreeze. Have the cooling system checked for a leak.
YesYes
A 1997 Jeep uses the regular green antifreeze.
A 2006 Jeep uses red, five year, HOAT antifreeze.
A 2008 Jeep uses red, five year antifreeze.
It depends on the year. After about 2002 all use red, 5 year antifreeze.
Most likely your heater core is leaking.
No, any antifreeze/coolant will do.
