How do i drain old engine coolant? no idea where

Hi ronaroll, YOU MEANT FORD EXPLORER SPORTRAC
WHERE IS THIS VALVE LOCATED IN THE CAB OR IN THE ENGINE BAY , IS IT AND AIR VALVE OR COOLANT VALVE HOT.
V6 OR V8 ENGINE? NOT TOLD , USA ??
IS HEAT LOST IN ALL OUTPUTS VENTS IN THE CAR OR ONLY SOME , NO PROBLEM TOLD. JUST A VALVE THING.

THE ANSWER IS YES,DRAIN IT.
IF YOU ARE TALKING THIS EXACT PART,
SEEN FOR SALE FOR YOU CAR


IF THIS IS IT? THE RULE IS (BY SEAMANS EYE)
IS TO LOWER RAD COOLANT BELOW THIS LEVEL OF THIS VALVE. HERE.
IT IS VACUUM OPERATED. DID THE VAC HOSE FALL OFF?
OR IS THE VACUUM SERVO THERE DEAD.
OR LEAKS FLUID.?????
THAT'S MY GREEN ANSWER , NOT SPILLING.
CATCH THE OLD. AND RECYCLE THE COOLANT

Question moved to model category.

To replace the freeze valve in a 1998 Cadillac DeVille, you will need to follow these steps:

1. Locate the freeze valve. It is typically located near the radiator or the heater core, and it is responsible for preventing the cooling system from freezing in cold weather.
2. Disconnect the negative battery cable. This will prevent any electrical accidents while you are working on the car.
3. Drain the cooling system. This will allow you to remove the freeze valve without spilling coolant all over the engine compartment. To drain the cooling system, locate the drain valve at the bottom of the radiator and open it.
4. Remove the freeze valve from the cooling system. This will typically involve loosening the mounting bolts or screws that hold it in place, and then pulling it out of the system.
5. Install the new freeze valve. To do this, you will need to reverse the steps you took to remove the old valve. Start by placing the new valve in the same position as the old one, and then secure it in place with the mounting bolts or screws.
6. Refill the cooling system. Once the new freeze valve is installed, you will need to refill the cooling system with the appropriate type and amount of coolant.
7. Reconnect the negative battery cable and start the engine. This will allow you to test the new freeze valve and make sure it is functioning properly.

It is important to follow these steps carefully to ensure that you replace the freeze valve correctly and safely. If you are not comfortable with performing this task yourself, it is recommended that you seek the assistance of a qualified mechanic.

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.

Here's a link to read about your Olds.Here's a kit that has instructions how to flush.You need to drain the system, the drain valve is located on lower driver side of the radiator. When the system is dry, shut the valve and fill the radiator with new coolant. Fill until the coolant runs out the top, fill the overflow tank to cold mark.
Start the engine and let it warm up until the thermosat opens. Standing in front of the vehicle there is a small bleed valve located on the right just above the thermostat open it until the coolant comes out and shut it back off. Located on the left of the engine just above the water pump is another bleed valve, do the same with it. You may have to do this two or three times before you have all the air out of the system.

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.

Easy to do at home. Requires the Coolant to be drained. My symptom was that the car took forever to warm up and the faster I drove the cooler the engine got which sucked in the winter.
1) Locate the Thermostat housing which is located at the front of the Engine, Passenger side, under the Air Conditioning compressor.
2) With the Cars engine cool, place a container under the engine where the Thermostat housing is located.
3) Loosen the Radiator hose clamp on the Housing, and pull off the hose from the housing. NOTE Coolant will start to gush out just make sure that the bucket or container is catching the coolant to avoid any spills. Removing the Coolant cap will make the coolant drain faster.
4) Remove the 2 bolts which hold the housing on the engine block. NOTE Coolant will start to gush out just make sure that the bucket or container is catching the coolant to avoid any spills.
5) remove the old thermostat, you will probably notice under inspection that there are some pieces of rubber seal missing on the valve which allow the coolant to bypass the valve, not good at all.
6) Replace the thermostat with one of equal temperature rating. Also replace the o-ring on the Housing while your at it, most replacement themostat kits have this included.
7) Make sure that the engine block surface where the housing sits is clean, and reinstall the Thermostat and Housing and Radiator Hose.
8) Fill the Coolant resevoir with GM approved Dexcool coolant.
9) Start the engine and check for leaks. Turn off the engine then top off the coolant again. Just be sure to remove the Coolant Resevoir CAP SLOWLY to equalize the pressure or you can get splashed with hot coolant BE CAREFUL!

1.) the drain valve is a bolt type device under the radiator..

2.) different flush has different methods usually buy the flush and follow the instructions.. usually
empty radiator by loosening valve underneath
tighten back valve when drained
pour in flush and top up with water
start car and allow to run for 15 minutes (with cap off)
cut off
let cool and then drain..

add coolant .. your done..

It is located at bottom of radiator, you will need 1/2 inch square drive or a 3/16 inch hex drive to open drain valve. Usually on pass. side at bottom end of radiator.

I Suspect that you have AIR in your COOLING SYSTEM Fallow Procedures BELOW to Insure there is NO AIR IN COOLING SYSTEM


Draining and Filling Cooling System

Draining Procedure

Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240,000 km, (150,000 mi) , whichever occurs first.

1. Park the vehicle on a level surface.
2. Remove and clean the coolant recovery reservoir.

Caution: Refer to Radiator Cap Removal Caution in Service Precautions.

1. Remove the radiator cap when the engine is cool:

3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap.
Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound.

1. Place a drain pan under the radiator drain valve in order to collect all of the used coolant.
2. Open the radiator drain valve located at the bottom of the radiator tank. If only partial cooling system draining is required, drain enough coolant to perform the procedure.
3. Open the air bleed valve on the thermostat housing 2 full turns
   1. Open the air bleed valve above coolant pump 2 full turns.
   2. Place a drain pan under the engine block drains in order to collect the used coolant.Important: Allow the coolant to drain completely.
      
      
      1. Remove both of the engine block drains.
      • The front left engine block drain is located between the starter motor and the engine oil filter.
      • The rear right engine block drain is located near the crankshaft position sensor.
      Filling Procedure
      Reinstall the engine block drains
      
   3. Close the radiator drain valve,
      1. Install the coolant recovery reservoir. Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL coolant. If Coolant other than DEX-COOL or HAVOLINE DEX-COOL is added to the system the engine coolant will require change sooner; at 50,000 km (30,000 mi) or 24 months.
      2. Slowly add a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water to the radiator until the coolant level is at the base of the radiator fill neck.
      3. Wait for 2 minutes and reinspect the level of the coolant in the radiator. If necessary, add coolant to the radiator until the coolant level is at the base of the radiator fill neck.
      4. Install the radiator cap.Ensure that the radiator cap arrow points toward the radiator overflow tubeImportant: The air bleed valves are brass. Do NOT over-tighten the air bleed valves.
         
         
         1. Close the air bleed valve above the coolant pump.
            1. Close the air bleed valve on the thermostat housing.
            2. Fill the coolant reservoir with a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water. Caution: Refer to Radiator Cap Removal Caution in Service Precautions. Important: If the coolant temperature indicator turns ON, turn the engine OFF immediately and allow the engine to cool. Do NOT remove the radiator cap.
            3. Start the engine and allow the engine cooling fan to cycle on and off 3 times. If the low coolant indicator does not turn OFF and the coolant level is above the Full Cold mark on the coolant recovery reservoir, refer to Engine Coolant Temperature Gage Inaccurate or Inoperative.
            4. Turn off the ignition.
            5. Allow the engine to cool.
            6. Ensure that the engine coolant concentration is sufficient.
