Radiator drain plug

1. Drain the coolant
The thermostat is located at the end of the top radiator hose. Remove the drain plug from the radiator and flush the coolant into a pan.

2. Remove the Upper radiator hose
Loosen the clamps that connect the upper radiator hose to the housing and remove the hose.

3. Remove the thermostat housing
Loosen the thermostat housing mounting bolts. Remove the housing and pull the thermostat from it.

4. Replace the thermostat
Inspect the new thermostat and install it with a new gasket. Mount the housing and upper radiator hose. Then pour new coolant into the radiator.

A friend's son had a car and we couldn't find the radiator drain plug. I finally just pulled the lower radiator hose.

Simply loosen the old one in the radiator to let the coolant run out. After the radiator is empty, pull the old drain cock out of the radiator and install the new one. Tighten the new one up firmly and refill with coolant. Let the engine run to reach normal operating temperature and check for leaks.

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.

Suzuki factory manual

1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary

Water Pump Removal & Installation To Remove:

1. Allow the engine to cool and drain the coolant from the radiator and both engine block plugs.
2. Remove the fan shroud and both radiator hoses.
3. Remove the drive belts.
4. Remove the water pump pulley.
5. Remove the crankshaft pulley.
6. Remove the timing belt covers.
7. Remove the water pump.

Water pump removal/installation

To Install:

1. Install the water pump with new gasket.
2. Install the timing belt covers.
3. Install the crankshaft pulley.
4. Install the water pump pulley.
5. Install the drive belts and fan shroud.
6. Install the radiator hoses.
7. Install the coolant drain plugs.
8. Refill the cooling system.

hello. on the drivers side of radiator is a drain. here is a picture and the instructions for draining the coolant out.

Install a tube on the radiator drain. Place the end of the tube in the drain pan.

After the engine cools down, remove the radiator cap.

Completely open the radiator drain ****.

Allow the coolant to drain from the system until the flow stops.

Place a drain pan under the block drain hole plug.

Remove the drain hole plug from the engine block.

Allow the coolant to drain from the block until the flow stops. There may be more drainage from the radiator at this time.

Install the block drain hole plug.

Close the radiator drain ****.

The overheating is caused by the sludge. It is very easy to correct this problem. Remove the radiator cap and open the drain valve at the bottom of radiator. If possible, remove the reservoir and flush out with water. Make sure to get all sludge out of reservoir, then reinstall. Once the radiator stops draining, insert water hose (without nozzle) and turn water on. Keep the drain valve open. Run water through radiator until it runs clear. Once it runs clear, start the engine and let it run while keeping the water running through radiator. Allow engine to run until the thermostat opens up. Continue running water through radiator with engine running until the water from drain runs clear. Once you have done that, turn off the engine. Close the drain valve and refill radiator with proper mixture of coolant and water. Once radiator is filled, start engine and let circulate through engine. Coolant level will drop as the coolant starts circulating. Shut off engine and top off radiator. Fill the reservoir with the required amount of coolant. Testing the coolant at least once a year will help prevent this from happening again. Coolant should be replace a minimum of five years, less if coolant bottle specifies.

you need to flush the radiator out.
With the engine cold, remove coolant bottle cap to release pressure.
Drain engine coolant from drain plug on radiator.
With the drain plug removed disconnect the highest hose connected to a radiator.
use an hosepipe and put it in place of the disconnected radiator pipe.
turn on the water to the hose pipe and let it flush out any sludge accumulated in the radiator. after a few minutes turn off water supply, reconnect radiator hose and drain plug and refil using recommended coolant mix for your galaxy (purchased at most autofactors and garages).
Also check your thermostat as if this is faulty it would stop the flow of coolant running around your engine.

hope this helps

make sure engine is cool then drain coolant by opening the drain plug at bottom of radiator. remove cap from radiator so coolant will continue to drain and when coolant is down enough to pull off upper radiator hose at intake then close drain, then remove two bolts at coolant housing and remove thermostate. clean gasket material from intake and housing and replace with new gasket and thermostate tighten bolts install hose fill rad with coolant water mix 50/50 and run engine with heat on floor until gets hot and you see coolant flowing in rad, install cap
