I HAVE A DODGE RAM1500 5.2L 2WD ABOUT 130K.
YESTERDAY IT GOT HOT ON THE WAY TO WORK. I PUT ANTIFREEZE IN IT (RADIATOR WAS PRETTY LOW). I DO NOT SEE ANY FLUIDS LEAKING FROM UNDERNEATH. WHEN I DROVE IT THIS MORNING IT DID NOT GET HOT BUT THE HEATER IS BLOWING COOL AIR. I ALSO NOTICED THE WATER GURGLING SOUND BY DASH(HAVE NOTICED THIS FOR A FEW MONTHS NOW)! NOT SURE IF IT IS WATER PUMP,HEATER CORE OR RADIATOR. ANY HELP WOULD BE GREATLY APPRECIATED! I DONT HAVE THE MONEY TO TAKE IT TO DEALERSHIP TO BE CHECKED IF I NEW FOR SURE WHAT PROBLEM WAS I COULD POSSIBLY DO IT MYSELF!

Try replacing the thermostat and bleed the cooling system.

BLEEDING COOLING SYSTEM:

Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks.
