Could a freezeplug blow out?

you have to check radiator and coolant liquid hoses, that could be blocked. if radiator and hoses is Good, then this means cylinder head gasket blowed and need to be change with new one.
ofcourse you also check radiator fan.

Your coolant system is leaking water.
Look under the vehicle for signs of the coolant whatever color it may be leaking down the engine.
If you have an automatic transmission, look at the fluid to make sure water is not leaking into the transmission via the cooler in the bottom of the radiator.
Check the tightness of all hose clamps on every rubber hose. Check the condition of the radiator cap and if it is older than 5 years, replace it with a new one anyway.
Take the overflow hose off the radiator and try blowing through it into the reservoir..if the system is dirty sometimes coolant is blocked from going into the reservoir when the engine heats up and therefore is dumped on the ground.
Check the reservoir for cracks.
Check it's cap if this is separate on your vehicle.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

Suzuki factory manual

The water pump is enclosed on the front of the engine. The bottom radiator hose connects to the water pump inlet.
You do not add coolant to the water pump. You add a 50-50 mix of antifreeze and water into the radiator cap opening. Or you can buy the coolant already mixed with water and just pour it into the radiator.

The coolant system uses the water pump to circulate the coolant through the engine and then into the radiator via the upper radiator hose for cooling it off, and it then goes back into the engine through the bottom radiator hose. When the engine is warmed up, the coolant constantly circulates through the engine to radiator and back into the engine.

sounds like the water pump is bad, new parts can be defective.

if it is not loosing coolant, then the coolant is not circulating. Moving the warm stuff to the radiator to cool and then cool stuff back into the engine is the way it is supposed to work. bad water pump or clogged radiator come to mind first. remove the engine ends of the two large hoses from the top and bottom of the radiator and dump water into the top hose, if it does not flow out the bottom hose at about the same rate, it may well be clogged.

unscrew the freezeplug located on the bottom corner of the radiator

You can change the water pump by doing these steps:

• With the engine off and cold, o pen the hood and locate the vehicle’s radiator and water pump.
• Remove the radiator cap.
• Install a pressure tester on the radiator. Apply the pressure indicated on the radiator cap or in the owner’s manual.
• Inspect the water pump for leaks. Remove the pressure tester.
• Place a drain pan under the radiator. Open the drain valve or remove the lower radiator hose to drain the cooling system.
• Remove the drive belts or serpentine belt.
• Remove any hoses connected to the water pump.
• Unbolt the water pump from the engine. Remove the water pump.
• Using a gasket scraper, clean the mounting surface on the engine block.
• Install a new gasket and attach the new water pump to the engine with the original mounting bolts. Tighten the bolts to the manufacturer’s specifications.
• Re-install any hoses and belts that were removed.
• Re-install the drain plug or lower radiator hose.
• Refill the radiator with a 50/50 mix of coolant and distilled water. Pressure test the cooling system and check for leaks.
• Check and fill the overflow reservoir with coolant.
• Leave the radiator cap off and start the engine. Idle the engine to remove trapped air from the cooling system. Add coolant if necessary.
• Install the radiator cap.
• Road test the vehicle and monitor the temperature gauge. If the vehicle runs hot, there may be an air pocket in the cooling system. Allow the engine to cool off and add the necessary coolant.
