1998 Lincoln continental low coolant level added coolant and coolant level warning cleared know car is overheating even after bleeding air

Engine or hydraulic system overheating Coolant system low on coolant in 6020, 6030, 6030 Premium, 7020, 7030 and
7030 Premium Series Tractors.

Symptoms
After several hours of work, warning system indicates hot engine coolant or hot hydraulic oil.
Situation or Problem
Coolant level in reservoir is between the "MIN" and "MAX" range but engine or hydraulic system is overheating.
Summary
Air is entering cooling system, hindering coolant flow. Check coolant level. Fill to the "MAX" line on the coolant reservoir.
Bleeding Cooling System:
The bleed valve (see Operator's Manual for location) on the radiator must be closed when the tractor is operating. Open the valve when coolant is drained or filled. If the bleed valve is left open, coolant will internally bypass between the low temperature circuit and engine high temperature circuit causing overheating. When bleeding the system, open the bleed valve and run the engine with no load for 5 minutes at 1700 rpm. Then shut engine off for 5 to 10 minutes before closing the drain valve. Check the coolant level. If level is below the "MAX" fill line, repeat this procedure until coolant level stays at the "MAX" line.

check your vacuum actuated heater valve assembly under the hood for proper function .possible malfunctioning thermostat

check coolant level,did you put right thermostat,could be air look,on top should be bleeder ,have to open to bleed the air,keep engine running.

What engine 2.2 or 2.4 ?
Important: On vehicles equipped with the 2.4L engine, open the coolant air bleed valve. The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.
Does the cooling fan come on ?
Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL™ coolant. If coolant other than DEX-COOL™ is added to the system, the engine coolant will require change sooner: at 50 000 km (30,000 miles) or 24 months.
Close the radiator drain ****. Remove the drain hose.
If previously removed, install the engine block drain plugs.
When installing the drain plugs, use pipe sealer GM P/N 12346004.
Important: On vehicles equipped with the 2.4L engine, open the coolant air bleed valve. The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.
Fill the surge tank to the base of the filler neck.
Start the engine with the pressure cap off. Let the engine run until the upper radiator hose starts to get hot.
If the coolant level in the surge tank is low, add the proper mix of coolant until the level reaches the full cold line.
Important: After servicing the cooling system, and if the vehicle is equipped with an intermittent low coolant light, an occasional low coolant light may be encountered during some extreme driving maneuvers. This complaint should be eliminated by removing the surge tank cap and adding coolant to a level just at or above the full cold line when the system is cold.
Install the cap onto the tank with hand tight pressure.

You need to bleed the air from the cooling system. To do this raise the front of the car as high as possible and fill the coolant bottle completely full, run the engine until it gets to high side of normal temp but do not overheat it, shut it off and run cold water over the radiator to pull the coolant in and expel the air from the system.

where do you put the coolant show me a pioctures

Sometimes the service engine light comes on when the censor in the coolant overflow gets low. Try adding a little coolant to the overflow to the appropriate level.

> Thought I had a air bubble but it has ran over fours off and on with the breather cap on the manifold open and still nothing.
This doesn't have much to do with the cooling system; you need to bleed either at the radiator cap (if your car still has one) or multiple cycles of cold-hot with the overflow open and refilling it as it drops. If with a cap, it is simpler; open the cap on a cold engine and observe the level while the engine warms up; once the coolant starts to flow, you should see the level drop and replenish until it no longer drops.
After you have done this, if your engine is still overheating, you may have a head gasket failure between combustion chamber and coolant channels. Even with this problem, you should have heat from the heater core.

First of all you need to check your coolant return bottle level, it's probably low, and needs coolant added. Heater will be starved for coolant, if level is low, thus, cool/cold air comes out. Try to add when engine is cool, to avoid getting sprayed with hot coolant. Leave cap off for a while, turn your heater on (not defrost) and let engine run up to temperature, and add more as needed while you watch level. Rev engine slightly and hold it for 5 seconds or so, every once in a while to help circulate coolant, and remove any air in system. If you have an actual rad cap, that you can remove and watch flow in radiator, that's even better, for adding and bleeding air out same way. Make sure your rad fan is working as well, and once you get it topped up, and heat back working, I'd seriously consider having a system pressure test done, as you obviously have a leak somewhere if the level went down to the point of overheating, and heater was starved for coolant. Keep an eye on that return bottle level until such time you have it checked, to avoid more damage to engine.

Check to see if the heater control valve is not opening,feel bot hoses,and they should behot to the touch.Did you bleed the air out of the cooling system?Coolant will not circulate if this is not done.
