Head Gasket Blown?
 

I have an 89 wrangler with a 2.5. I fill the radiator and cooling
system. It idles and warms up. I take it for a short ride and by the
time I get back the radiator is empty and just steam comes out of the
radiator when cap removed. Is the head gasket getting blow by and
pressurizing the system causing the coolant to pour out of the overflow?

Re: Head Gasket Blown?
 

Does the fluid come out the overflow? If is coming out the overflow then
the system is not cooling. Maybe a stopped up radiator or a fan problem or
air in the system. A bad head gasket causing coolant to burn would be white
smoke/steam coming out the exhaust I think.

When I park the vehicle after driving it, there is coolant coming out
of the over flow and a trail of coolant behind the vehicle. I did
notice while the engine warms up the heater hose is hot but the large
hose from the radiator to the thermostat housing stays cool. Is this
normal?

A stuck thermostat can cause the engine to overheat blowing out a mess
of the coolant.

I would try topping it up, then warming it up with the rad cap off to
see if you have circulation. or not.
