1 st drain the oil if excessive for it will just aggitate in the oil pan and it will not pump through the oil pump resulting in internal engine damage. The belt should be replaced every two years on any Northstar motor. A tune up is also recomended as well with high milage
a 6ya expert can help you resolve that issue over the phone in a minute or two.

White SWEET smelling smoke, or white OILY smelling smoke? If it's white thick SWEET smelling smoke, you have a blown head gasket - that's the smell of antifreeze burning in the engine, which it should NEVER do. If it's white OILY smelling smoke (smells a lot like diesel), then you're getting too much fuel into the cylinders.
If it's sweet-smelling smoke (antifreeze), pull the oil dipstick & check the oil level. If the oil level is HIGH and the oil looks like a mocha milkshake, that's absolutely conclusive - that's what happens when antifreeze gets into your oil, and it's nasty corrosive to engine parts.
I'm not at all surprised that the oil light is on if it won't start - you won't get much oil pressure until the engine is running.
overheating sound like faulty thermostat.thermostat either sticking close or could have blown headgasket if you see a lot of white smoke coming out of exhaust.if headgasket is leaking check engine oil should look milky.also check water pump look around weep hole or see coolant leaking around water pump replace water pump.also check water pump drive belt.make sure drive belt not loose slipping.
usually: white smoke is coolant leaking into the combustion chamber
blue-ish smoke is oil in the combustion chamber
black smoke is excessive fuel (running rich)
If it is white smoke, pull the oil dipstick and check to make sure your not getting coolant in your oil. If thats okay check the compression on each cylinder to make sure your head gasket isn't leaking.
if your car is burning oil, you may need to replace your PCV valve(about $5). As far as oil additives, try RESTORE
High temp could be low coolant check your coolant level. Low oil-check for leaks, if no leaks then check for blue smoke out exhaust, if no blue smoke it could just be low. A vehicle will go through a quart of oil between oil changes, even a newer one.
If you are having a lot of white smoke all the time the car runs then
check for coolant mixing in with the oil,look for water in the oil when
you check the oil or milky brown oil. This produces a white "steam" that
is very thick to come out of the exhaust. If your engine temp. gauge is
very high and over heats you probably have a blown head gasket. If it
has a bluish tint look it may be burning oil. Indications might be how
much oil is currently in the car i.e too much oil, or if there is a leak
in the line you may be adding a bunch of oil over a short time. If it
is only when you first start the car and the engine is cold, then it may
be that your valve seals are bad and need replacing.
Somehow water has or is being burned,check coolant level and temp if you
have temp light put a guage in if coolant low there is your problem if
not check egr valve and pcv valve also check oil level if high and milky
there is high possibility that you have blown head gasket and or block
may be cracked allowing oil to get into the oil pan.
If you are loosing radiator water/antifreeze and you see 'white' smoke out of your exhaust then it is likely that you are seeing steam: this usually indicates that you have a blown cylinder head gasket or have a cracked ylinder head: both situation will cause overheating of your engine. You can also check this situation by waiting until the engine is COLD, opening the radiator cap, refill with clean radiator fluid/water, restart the engine and see if the water as seen in the radiator is violently bubbling. Another condition before even starting the car again is if you see oil/white-brown staining in the radiator fluid caused by cracked cylinder head or gaskets letting engine oil in the radiator circuit. In any case, it is a critical sitation and you should get it checked and fixed immediately.
Hope it helps and please let me know if I have assessed the correct situation.
Could be three things: Hopefully the first...
1. radiator fan not blowing. (most likely)
2. Radiator clogged (not likely)
3. Head gasket blown... (very possible)
If #1, system cannot detect fan not blowing. It may be the fuse or the relay switch, disconnecetd wire at fan, or burned-out fan motor.
If #2, Flush radiator
If #3, you will see WHITE smoke out the tailpipe and excessive water drops.
Your new oil will have a "milky" look (check the oil dipstick). That is water.
When engine is COLD, remove radiator cap and start car. You will notice high-pressure "bubbles" squirt out of the radiator, even before the engine warms up.
