A car's cooling system is a "closed" system. If the radiator cap is working properly, you can do a test by just starting the car, let it run to normal operating temperature, or you can speed up that process by driving it around the block, or if you need to go to the store. When you get back home, just lift the hood and squeeze the upper radiator hose being careful not to burn your hand. if that hose is tight, you do not have a leak, If there is any kind of leak in the system, it will make itself known. if the heater core is blown, you will see and smell antifreeze in the interior. A cracked head, depending on where it is cracked, it may show up as water in the oil. ( a milky color under the oil cap )

Is your car smelling funny? If so then the heater core is bad. If you have no indication the heater core is bad then are you loosing coolant? Take the radiator cap off and start the car. Put your hand over the radiator. If you feel pressure in the system, then you do have a blown gasket or bad head. You need to do a compression test. If you have one spark plug that seems really clean, that will be where the coolant is going. Good luck. Need more info to be more helpful.

Get a pressure test. The cooling system is pressurized, and the leaks make themselves known.
If you have a blown heater core, you would probably be smelling coolant whenever you run your heater.
Check your oil, if it's frothy, you most likely have a head problem.

Fan won't count approximately 35 mph, and the heater middle certainly acts like a mini radiator and can certainly help in cooling off the engine. i will assert that radiator people will inform you that wanting knocking the caps off and examining the tubes, there is not any thank you to certainly tell if the radiator is flowing adequate coolant or no longer. yet truthfully you have replaced each little thing wanting the radiator. additionally what approximately coolant in computerized transmission? It shares a cooling tube with vehicle transmission

If your head is cracked you will get:
1. Water in the oil and/or
2. Loss of compression usually only in one cylinder and/or
3. Water into a cylinder.
A blown heater core will leak onto your carpet.

pressure check the system, you can pull the plugs and watch for water, you can look underneath the heater core and look for coolant and so on

THE TWO AND EASIEST WAYS TO CHECK IF YOU HAVE A CRACKED HEAD IS TO START THE CAR UP AND THEN GO OUT AND TAKE THE RADIATOR CAP OFF AND AFTER THE CAR GETS UP TO TEMP AND THE THERMASTAT OPENS UP LOOK TO SEE IF YOU SEE ANY BUBBLES COMING UP TO THE TOP IF YOU DO THEN YOU HAVE A CRACKED HEAD OR ATLEAST A BLOWN HEAD GASKET THE OTHER THING TO CHECK IT TO PULL THE DIPSTICK OUT AND SEE IF YOUR OIL IS TURNING WHITE IF IT IS THEN YOU ARE GETTING WATER INTO THE CRANK CASE AND THAT MEANS YOU HAVE A CRACKED HEAD OR A BLOWN HEAD GASKET ATLEAST.

pressure check. you can check and see if the floor is wet on the passenger side and up under the glove box. Pull your dip stick and breather off the valve covers and see if theres water in the oil its foamy and yellow looking most of the time.
