Check the temp sensor. The control is not turning on the fan when engine temp requires it, so the most common cause is the sensor.

Not 100% sure about the Toyota truck, but I had that same problem with a late 90's Chevy. Turned out to be the clutch fan ($25 part) after I had replaced almost everything in the cooling system.
My dad had the same problem with his sundance and it turned out he had a cracked head. Answer Check your heater, if you turn your heater on and it blows cold air, then its is likely that the water pump has either failed or the belt has separated, either by age or because the pulley has fallen apart (plastic - replaceable)
A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.
mine overheated a lot, turned out to be the heater core.
rad hoses route coolant to the engine to maintain operating temperature (to keep engine from overheating). Heater hoses supply the heater core (inside most vehicles) with hot water, when heater/ac temperature control knob is turned toward hot, to heat the interior of the vehicle by opening and closing a water flow control valve allowing water to enter the heater core for heat. =;)
First, you need to find where the bubbly noise is coming from. More than likely, it's from your radiator overflow canister and means you have an overheating problem.
