2000 mitsubishi eclipse coolant leak and car smoking.? My coolant reservoir has been dry for several weeks now. Stupid on my part I know, but it's the third time it has gone dry in the past three

It is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke. One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located. THESE LEAKS WILL CAUSE SEVERE ENGINE DAMAGE! Have the car inspected immediately.

Internal coolant leaks can and will cause

Where is the smoke coming from, Is it coming from the exhaust of engine bay. Colour of smoke?

Do you know where the leak is on the tank, and what the trouble codes in the computer are ?

Unfortunately this will be kind of hard but, it sounds like you may have a blown head gasket depending on where on the passenger car it's leaking? Drive the car get it hot. Leave it running get out and pop the hood. Start looking for leaks. Use a powerful flashlight to help look. If it doesn't leak while you're driving and only after the car is shut off then I'd say you're creating a vacuum in the coolant system, change your coolant cap at that point.

You'll need a cooling system pressure tester to put pressure in the system and it will force the coolant out of the area where it's leaking. Water pumps are common as are heater hoses. Sometimes it's really hard to find the leaks. If you've overheated too many times, you may have warped the cylinder head and that will cause a major leak. Look for white residue around the head/block and should point you in a genreal direction.

Defrost is turning the fans on so there is probably an issue with the fan controls on the car.

Just as a possible solution just to close the roof, remove the motor and try an manually pull the roof closed, if it does'nt move it could possibly be the operating rack that pulls the foor back and forth, in which case it will require dismantling the roof assembly

Looks like bypass hose or engine coolant plug just got leak! look at ur coolant reservoir, it might overflowing when ur engine heats up and its dripping towards the engine! Look and search all the hoses in the side of the engine and reservoir! If its the bypass hose, there will be a difficulty in removing and replacing it, but u could fix it! taah!

is the car smoking or is white smoke coming out of the exhasut pipe, could be a small leak in the head gaskets

does the car blow white smoke out of the exhaust when its running?
