We replace it with:
ANY COLOR ANTIFREEZE
ALL MAKES ALL MODELS
of cars and light trucks
add to ANY color antifreeze
PRESTONE.

It's up to you. Ask before, but if you decide to change the type of coolant then:
If your intention is to add coolant only, then you need:
PRESTONE 50/50
PREDILUTED ANTIFREEZE/COOLANT

If your intention is to flush the RADIATOR (Cooling System), then you need:
Mix with
ANY COLOR ANTIFREEZE
ALL MAKES ALL MODELS
of cars and light trucks
add to ANY color antifrezze
PRESTONE
EXTENDED LIFE up to 150000/mile 5 year protection.
On the back you have to read directions:
Step 1 Drain. Step 2 Flush. Step 3 Fill.
Recommended to ad 30% volume distilled water to 70% volume Antifreeze. If you flush the system and rinse with water you must add only 30% water to the antifreeze. There is more water trapped inside the engine compartment, because the thermostat is closed. Make sure to have a coolant density tester. When you finish one of 5 balls must sink, that indicates that you reached 50/50 strength. That means 50% Prestone and 50% Water, which will provide to your car a -34F degree FREEZE-UP Protection , and +265F degree BOILOVER protection. Make sure to open bleeding valve to discharge air pockets from the cooling system. Add coolant.The next day,while engine is cold open the radiator cap, and test the strength of coolant. If it is not quite right, then siphon coolant from the radiator and add antifreeze, or distilled water as necessary.
Let the car to cool down overnight and start engine. The cooling system might be cold. Untwist the coolant bleeding nipple. If there will be a jet or stream of coolant, that means the water pump is working and is O.K. After replace the thermostat. If still your car overheats then it might be a bad cylinder head gasket.

How do I drain coolant from a 2001 ford mustang GT?

temperature rising no water leaks both cooling fans working in a tropical country


I would suspect your thermostat is sticking partially closed. You car is 8 years old so it is time to service the cooling system. Drain the coolant, flush the system, replace the thermostat, and fill with a 50/50 mixture of antifreeze and distilled water. Bleed all air from the system. I am assuming you are not loosing coolant with no apparent leak. If you are then you may have a blown head gasket, especially if you see white smoke from the exhaust.

air conditioning works but not heat. blows out


At the radiator, drain and then flush with water then add 1 gallon of new antifreeze and top off with cool water. Now the cooling system will work.
If you have not performed routine maintenance on your cooling system - it will clog the heater in 10 years or less. Sometimes a bottle of radiator flush (purchased at any walmart or kmart) can clear the heater core - but you will have to run it with the heater on full heat setting for a few hours of driving.
