Is the cooling fan coming on? If not, check the fuse, fan thermostat and fan itself. Make sure the radiator is not clogged or blocked (either inside, or outside). I all that checks out, check the engine thermostat. I hope this helps you.

SOURCE: 96 cavalier overheating

You have a front wheel drive car so it requires and electric fan motor which in turn requires a temp sensor to tell it to turn on. The sensor should be on the radiator itself. Check that the connector to the senor and the motor are tight and if the wiring checks ok then I'd go for the sensor first.
The reason it cools while driving is the natural flow of air at driving speed.

Temp gage is solid red, air conditioner is now blowing hot air. Filled coolant reservoir and it emptied while driving but mechanic found no leak with pressure test. Is this a thermostat issue?


I doubt it.
A faulty thermostat would cause the engine to overheat after a few miles of driving. A faulty cooling fan could cause the engine to overheat and also keep the ac from working.
A leaking head gasket could cause overheating, and loss of coolant, but would not affect the ac.

Van keeps shutting off on its own and overheating


you mean the engine, overheats then the engines stalls.?
that latter symptom is normal for overheating.

(some exceptions, ) my Corvette drops cylinders, 1 by 1 to stop
this.(but is still bad , if this happens)

does it overheat only stopped, only moving or both? (KEY question)

fix the over heat, cause. there are may ways to overheat.
from simple to comlex. and no web bunny on earth can guess it.
unseen.
ill list the simple:
1: low on coolant, no not the side tank, the actual rad is low,
check only on dead cold engine,below 125F (AZ temp)
2: bad RAD cap. not holding pressure.
3: wrong coolant mix or mixing 1 color coolant with another (bad)
4: water pump belt bad , or slipping or missing.
5: rad tubes clogged
6: fan dead,
7: RAD outside ofcore, blocked with filth.
8: blown head gasket,(or far worse)
9: bad water pump.
10: leaks anywhere, (this really is first)

Overheats because engine coolant backs up into reservior.


That's not the cause. That is the effect of boiling. Start out by pressure testing the cooling system to locate any loss of pressure and repair it. It's possible that previous overheating has led to head gasket issues now.

'02 626 overheated earlier in the week. drove home. appeared to be out of coolant. replaced overflow tank(seal blown), added coolant, however it still overheats. what else to check?


Whenever you overheat once, then the thermostat must also be replaced. It is operated by the expansion of a contained wax pellet, and overheating causes permanent loss of wax.
However, you may also have caused a head gasket leak now from heat warpage. If the thermostat does not help, then borrow a cooling system pressure checker from a place like Autozone, and see of it holds pressure for 5 minutes after pumping it slightly above cap rating. Then start engine and see if it is steady or oscillating from 1 cylinder leakage.

Over heat


If the head gasket goes water is allowed to seep into the cylinders and then out of the exhaust.

Once the level has dropped enough the car overheats

Or the water is pressurised in the radiator from the compression of the engine and it is forced out of the overflow leading to coolant loss and overheating

Overheating


  1. There are many different reasons that can cause an engine overheat, but they all have in common three aspects. The three aspects which all engine overheat factors have in common are that they cause that the heating system can not get rid of heat, they cause a loss of coolant or they directly cause too much heat in the engine.
  2. One first problem which might be the cause of an engine overheat is a problem with the radiator cap and the pressure it holds. If the radiator cap does not hold pressure correctly then coolant could boil and therefore the engine would overheat. Another reason might be caused by thermostat failures; it is recommendable that you check it.
  3. The car engine might also overheat due to coolant leaks such as those from the radiator, the hoses, the water pump, the freeze plugs or any others. Also, problems in the water pump could be the cause and therefore you should check it and replace it in case it is needed.
  4. Some other reasons by which the car engine could overheat are problems in the exhaust system which you can discover by checking vacuum readings, pipes and converter. Besides, you should also make sure that the radiator hose has not collapsed and the ignition timing is working properly.
  5. You should also check the electric cooling fan by making sure that the fan motor, the relay and temperature are correct or otherwise it could cause the engine to overheat. Besides this, you should also check the radiator in case there are any debris in it as well as you should check its hose in case it has collapsed.
  6. It is also recommendable that you check the antifreeze concentration which should be 50/50 in order to be correct, otherwise it could cause the car engine to overheat. If you do not find why your engine does overheat, you should ask a mechanic or an expert for advice. You should not try to fix this if you do not have the proper tools and general car knowledge necessary for it.
