The thermostat or heater core could need rebuilding.

Are you getting coolant flow through the heater core? These cars have common problems with heater cores but they are easy to replace. IPD has a Video on U-Tube with step by step instructions. Also if you are in very cold weather have you checked your anti-freeze? I saw a Toyota last year freeze completely because of no anti-freeze. It took days to thaw out the heater core and they were lucky that the ice did not blow it apart. It took me hours of starting it and running up to a low temp and shutting it down to get it drivable.

white smoke is caused by-- water or anti-freeze entering cylinder . if in radiator or the overflow tank. it will look like a chocolate milk shake. check on oil dipstick for traces of water or anti-freeze. also, a bad head gasket will let water or anti-freeze in combustion area. head gasket symtoms if bad. Symptom #1: Chronic Engine Overheating
Symptom #2: Significant Drop in Coolant Level Symptom #3: Mixing of Coolant and Engine Oil
Symptom #4: White Smoke from Exhaust Pipe
popping of overflow cap Symptom #6: Air Bubbles in Radiator
Symptom #7: Engine Lacks Power GOOD-DAY!

sign that the thermostat is stuck open, which is just allowing your anti-freeze to flow through all the time an therefore making it run cooler at a higher rpm or low anti-freeze level

It could be one of two things.
1. Bad thermostat. Your thermostat is pobably not opening when the engine warms up. Install a new thermostat and you should be OUT OF THE COLD. If not,
2. Your heating core and radiator is probably clogged. One way to solve this is. Flush out your radiator with radiator flush kit. Pease read your owners manual, (YOU NEED TO USE A SPECIAL TYPE OF ANTI FREEZE). If you use the the green color Presotne anti freeze, It will gradually corrode through the linings of your radiator. And the green color prestone anti freeze will blow out the radiator. So read your owners malual ( I beleive it says you have to use Dextron Anti Freeze ( Pink Color).. Replace your thermostat and flush out your radiator. Then refill your radiator with dextron anti freeze. Also make sure the anti freeze resivor is filled to the proper level.. Once you do all of this, YOU DEFFINITLY WILL BE IN HEAT.. YOU CAN DO THIS YOUR SELF ( iT WOULD TAKE ME NO MORE THAN 1 TO 2 HOURSFOR ME TO DO THIS IN MY DRIVEWAY) OR YOU CAN HAVE THIS DONE AT ANY QUICK LUBE LOCATIONS... HAPPY MOTORING

U have low anti freeze wich is causing the engine temp to run higher than normal and the fans blowing help bring it back down u can take wash off the motor let it run for a while when the anti freeze is full and watch to see if u can see green fluid coming out fix the leak if there is no leak found u need thermostat

First thing to check is the radiator cap seal. If it is not sealing properly, the water will boil off and then soon, the anti freeze will begin to disappear. Clean the metal surfaces and gasket and make sure it is tight ---or buy a new cap --but make sure there is a seal. If that doesn't cure it, you may have a head gasket leak that blows the coolant (anti freeze) into one cylinder. If that cylinder is tight, the coolant will only evaporate in the heat and be blown out the exhaust --not entering the oil pan. Check your exhaust when you start up. You may see white smoke, or even liquid, exiting the exhaust pipe, indicating a blown head gasket (then engine may run rough, too). If this is the case, there are reasonably inexpensive cures for this in some cases.

AND THERE IS NO COOLANT ON THE GROUND? IF NOT THEN U MUST HAVE A LEAKING HEADGASKET.
