Re: 2001 chrysler seabring put anti freeze in reserve box...
Cracked head or head gasket will cause antifreeze to get in the combustion chamber and be ignited with the gasonline.
The white smoke when you first start lets you know of this condition. Each cylinder will need a compression check to test for leaks.
Pressure checking the cooling system does not provide you with enough information.
Its possible that your coolant is slowly being burned off in the cylinders possibly caused by a blown head gasket or cracked head,also i would definately check your oil and see if its overfull or milky looking,usually indicates a head gasket problem also.If your intake gaskets are leaking internally your engine could be sucking it in and burning it. With no leaks coming from the vehicle these are about the only things it could be!!

There is such a thing as a "radiator pressure tester".
It is a hand-held device that you pump up by hand and it will pressurize the cooling system, and show you where it is leaking.
When you do that someone will need to have a strong light, and have the car up in the air, and look underneath for the problem.
Most often, the problem will be a failed rubber hose, often a heater hose that you cannot see from up above.
God bless your efforts.
flushing a radiator is a waste of time and money as blocked cores do not flush. Have a pressure test done on the coolant system and check for external leaks. have a compression test done to check for head gasket and cracked head. Have a flow test done on the radiator and if shows signs of blockage replace the radiator .. Always fill the radiator at the radiator cap and not the reserve bottle. The reserve bottle water will not go down until the engine coolant starts to cool so if it is going down when the engine is hot then you have a bad leak in the reservoir bottle.
Have your Cooling System pressure checked. Also check your oil and anti-freeze. If the oil is milky or the anti-freeze is oily you have a blown head gasket. Watch for white smoke (Steam) coming out of the tail pipe after it is warmed up. If you have white coming out that is coolant, black is fuel and blue is oil. After the pressure test if there are no leaks detected in the hoses then get a compression test to see which cylinder is leaking.
Due to the complexity of the newer cars on the raod today!! what you are experiencing is Normal!!! since the coolant systems on the newer cars run at such a higher pressure and a high Rpm the reserve tank which has it's on drain hose for excessive overflow from the radiator allows the extra high pressure release from the radiator to back flow to the reserve tank and then out the reserve tank overflow hose on to the raod
Fill the coolant system back-up to level and pressure test the system. Check for chalky, white trails, antifreeze trails, spots on the ground, and see that the pressure is holding for more then five minutes. Could be: head-gasket, freeze plug, hose, heater core, water-pump, or radiator.
You are probably low on fluid.
Behind the rear seat is your motor/pump/reservoir combination.
With the top DOWN, fill the reservoir to overflowing with ATF.
Cycle the system a few times and repeat.
Do this till the reservoir will take no more fluid.
Check the lines and cylinders for leaks. The fluid must be going somewhere.
If you replace any lines or cylinders, always do them in pairs.

If it's leaking at the top of the engine down. Look at the top of the engine at the front and you'll see a bleeder valve on top a black housing. These housings like to come apart at the glued seams. If it's leaking at the lower part of the engine towards the front, it could be your water pump leaking. Check your oil and if you see the color of the oil looking like chocolate milk, your water pump needs replaced, the oil will need changing as well. Do a coolant system pressure test and see if your hoses somewhere are leaking. Also check for your surge tank leaking. This is the tank that you put coolant into.
