White smoke from the exhaust may be an indication that coolant is leaking into the combustion chamber. This could be caused by a faulty cylinder head gasket, a cracked or warped heat or cracked block. Check the coolant level, and check to see if the oil dip stick has a milky look.
it sounds to me like the car is in need of a mojor flush and possible fan swith temp module. that could cause the radiator cap to over pressurize and shoot water out . can you give any more details? does it cool back off when you drive?
The white smoke is probably steam caused by coolant getting into the cylinder(s) either from a faulty head gasket, cracked cylinder head or cracked engine block. The loss of heat from the heater indicated that coolant was being lost..
coolant leaking into engine probably blown head gaskets. More damage will occur the more you drive it. Unfortunate and expensive repair on a northstar.
You have a head gasket leak. The gasket is allowing heat/exhaust to pass from the exhaust ports to the cooling jacket (antifreeze). This makes the coolant grimmy. As you move from traffic to park the car, there is no more exhaust gasses pressurizing the exhaust ports and now the hot, pressurized coolant is allowed to move from the cooling jacket into the exhaust port, turn to vapor and escapes through normal exhaust routes.
White smoke is a sign of bad head gasket, did your car over heat, if so blown head gasket, any auto repair shop can do a block test, this will let you know if cylinder head gasket is bad.
Hello;
Volumes of white smoke is an indication of water in the exhaust. A certain amount of vapor will be present on start up, but if it is different than what has been the norm for this vehicle then a check of the cooling system is in order.
