93 ranger 4.0 coolant boiling???

[py350]

My 93 ranger's coolant is boiling I have changed the fan clutch and t-stat and the water pump and radiator. The truck doesnt over heat but when driving for a long time and I park truck and shut it off you can hear it boiling. Maybe air in the system? or a head gasket issue? any input would be great thx...

Have you replaced the radiator cap???

what exactly is going on? is the truck getting hot? is it spitting fluid out of the overflow resivoir? or are you just hearing a boiling sound?

Sometimes I hear what sounds like a boiling sound when I turn off the truck, but it is just fluid gurgling in the AC system.

same issue here. Never overheats or leaks, just gurgles.

trk doesnt get hot according the gauge speakin of gauges on the temp gauge as long as it stays in the normal part between the C and H its a good temp right?

Think I found the problem... I felt the radiator and the top is hot but the bottom is really cold so I think the radiator is clogged or air in the system...

flush it out the radiator that is.
