After sitting overnight, resevoir is empty, engine struggles to turn over. When cranked, very much white smoke from tailpipe for five minutes. Have been told that I have a hole rusted in the plenium, leaking coolant into the engine. Is a plenium the same as a manifold? where is the plenium located?

Re: coolant dissappears with no visable leaks.
Yes the plenium is part of the intake.dont mess around otherwise you will blow the engine.it should cost on more then 400.00 dollars to fix.If your broke.you can try using a engine block sealer.that stuff has worked for me in the past.

You must have a coolant leak. If there are no signs of a leak, you may have a gasket on the engine that has gone bad, and the coolant is being pushed out the exhaust system. The coolant expands when hot and cools when the engine cools. During the cooling stage the cooling system creates a suction on the coolant in the reservoir and draws enough coolant back into the system to keep it full. Apparently you are loosing enough coolant somewhere that the reservoir can not fill the system before going dry.
Your owners manual should have step-by-step instructions. If that is not available this is what I would do: With the engine "overnight cold", that is to say after sitting all night, locate the coolant resevoir (forgive my speeling please), you will notice on the side of the resevoir notches telling you where the level should be when, cold fill the resevior to this level, if you over fill it don't worry. Never put coolant in a radiator with a hot engine you can crack the engine block, and/or burn yourself badly, also make sure you use not only the proper coolant but a good quality one as well. I hope this has helped you. :-)
The coolant bottle is on the passenger side and black in color. Wait til cool and simply remove the cap by unscrewing it. Top off to the line on the exterior of the bottle and replace the cap. If the resevoir is empty (take a flashlight and peer in), start the engine from a cold temp. and turn the heater on high to ensure that there are no air bubbles in the system to create an issue. Fill the resevoir until you reach the level on the exterior. If it is empty you need to get it looked at and find this leak before it overheats and destroys the head gasket. Let me know if you need anything else.
this is a sure sign that theres a blown head gasket and maybe a crack in the cylinder head, the engine is burning the coolant, the white smoke and the hard starting is due to coolant entering the combustion chamber and burning it and will cause overheating and other problems, this car can not be driven,the is a costly repair,
it could be a blown head gasket or could be a stuck thermostat causing the coolant to bowel and the only place to go is out the resevoir bottle pull your oil dipstick check to see if you can see little water bubbles in the oil on the stick this kinda gives you an idea if the head gasket is blown because most of the time the coolant will mix with the oil if the thermostat is stuck close it will lead to a blown head gasket if you dont get it taken care of also you may have a slow leak in the water pump and once the level gets low its going to bowel whats left and the stem will come out the over flow tube on the bottle
you could have a blown head gasket and coolant could be leaking into your combustion chamber.
rent a radiator pressure tester and see if the cooling system will stay at constant pressure. If the pressure drops you have a leak, and it could be your gaskets. pretty costly to repair.
make sure you have not blown the seals on the engines water pump. when they go out, the burst disc on the pump open and gush coolant everywhere.
You may very well have an internal leak as in a blown head gasket. If you see white smoke from the exhaust and it smells sweet that is a definate sign you do. You may also notice a white foam on the underside of the oil cap and the oil level may be over full. Remove the radiator cap, engine cold, and start the engine. If you see air bubbles escaping you have a blown head gasket or cracked head. Stop driving the car until you verify this with a compression test. Severe engine damage will occur if you continue to drive this car, if the head gasket is blown.
Thick black oil generally does not indicate coolant in oil...that appears as coffee coloured residue with a milkshake thickness to it. But, I'd let the car stand overnight and then drain oil. coolant will stay at the bottom of the pan and exit first, so watch carefully. Next, have a shop dye check for leaks...often small leaks are in the form of seepage that is light enough to evaporate on the hot engine before reaching the ground. Another test you can do is to let it sit overnight with the radiator cap off. Sometimes a water pump seal will only leak when not under pressure. (like when you try to empty a can of dog food...punch a hole in the bottom of the can and it will fall right out!) Also, check the rug inside the car...any dampness indicates a leaking heater core. I hope at least one item here will help. Obviously if you are loosing coolant, it has to be going somewhere. PS: use a good grade of synthetic oil and it should not break down as quickly as what you are using (regardless of if contaminated or not)
