Question about 2005 Chevrolet Equinox
These trucks, and most GM vehc. Had a problem with intake manifold gasket deterioration. Probably need to replace the intake manifold gasket. Make sure you check the oil also as usually coolant mixes with the oil also. Be careful this can cause seveer bearing damage and catastrophic engine failure. Good Luck.

Usually a sign of a blown head gasket or intake gasket or, gulp a cracked head or block. Check your engine oil for a milky color, This would confirm a blown head gasket. There is a test to determine if hydrocarbons are in your coolant. If your coolant level is low or empty, this is another sign.

SOURCE: white smoke comes out tail pipe
Its perfectly normal.Hot exhaust gases mixing with cold air and by products of the combustion process create the watery substance that you see spit out .Dual fuel (LPG,Hydrogen etc) vehicles do this a lot more noticably.By products of the combustion process are various but water vapour is one of them.Alot of heat is generated by the exhaust so watching a car driving in very cold conditions you can see this effect more clearly

SOURCE: white smoke from tail pipe
It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings.

White smoke is caused by water and or antifreeze entering the cylinder...If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
Good luck..i hope this helps.... please rate me a fixya
