I'm flushing a 1988 Chrysler Newyorker 3.0 liter

With a cool engine remove the rad cap and run the engine for awhile and usually any air will work itself out.

Cooling System Draining and Filling (Static Fill)

Draining Procedure

Warning! In order to avoid personal injury, do not remove the cap or open the cooling system drains from a hot system. Allow the system to cool first.

ImportantA 7.6 liter (8 qt) coolant container will be needed.

1. Place the coolant container under the radiator drain **** located at the bottom of the right radiator end tank.
2. Open the drain **** and drain the coolant. A small amount of coolant will drain from the system.

3. Remove the surge tank cap from the surge tank and the coolant will drain from the system.

4. For LE5 and LAT vehicles, if the engine block needs to be drained, a drain bolt is located near the bottom of the water pump assembly.
5. Inspect the coolant.
6. Follow the appropriate procedure based on the condition of the coolant.
• Normal in appearance--follow the filling procedure.
• Discolored--follow the flush procedure. Refer to Coolant System Flushing .

Filling Procedure

Caution! All entrapped air must be purged from the powertrain cooling system before the final coolant level can be determined. Proper coolant level is critical to avoid engine damage.
ImportantThe vehicle must be level when filling the cooling system.

1. Slowly add a mixture of 50/50 DEX-COOL antifreeze and clean water to the coolant surge tank. Fill the cooling system as indicated below:
• For LE5/LAT vehicles when the engine block is not drained, add 3.5 liters (3.7 qts)
• For LE5/LAT vehicles when the engine block is drained, add 6 liters (6.3 qts)
• For LZ4/LY7 vehicles, add 5 liters (5.3 qts)

2. Start the engine and check for leaks.
3. Run the engine and cycle the vehicle from idle to 3,000 RPM in 30 second intervals until the engine cooling fan comes ON, the engine cooling fan turns ON at approximately 102°C (216°F). Repeat this process twice before the engine is turned OFF.
4. Return the engine to idle, and idle for 30 seconds, then turn the engine OFF.
5. Allow the vehicle to cool, before adding additional coolant.
ImportantThe level in the surge tank will return into the cold fill range once the vehicle cools.

6. Add additional coolant to the surge tank until the level is approximately 13 mm (0.5 in) above the surge tank seam.
7. Install the coolant surge tank cap.
8. Hope this helps.

Best way ? take it an have a vacuum flush an fill .

I know the satisfaction of doing a job yourself but flushes are a menu item at many shops and also are sale priced. Typically you can find a coolant flush for $80-$90 retail. If you look around you should be able to find %15-20 off or $15 - 20 dollars off that price. For $50 - 60 dollars and a half hour of your time it's hardly worth doing yourself.

Hope this helps (remember to rating and leave us some testimonial comment)

THIS IS NOT THE FIRING ORDER. Honestly just look at it, 123456? There is no way that is right. The order is right on the distributor cap I bought and works perfectly on my 1988 Chrysler New Yorker. It is 1,3,5,4,6,2 going counterclockwise on the cap.

Coolant capacity is 7.7 qts./7.3 liters, for a 2.4 liter 2003 Kia Optima.
You will not be able to get all the coolant out of the engine, unless you do a thorough engine drain and flush. If you only plan on draining the radiator, you will need less than 2 gallons mixed total to refill it, since some coolant will remain in the engine block and heater core.

switch for brake lights on the pedal ,drain engine coolant to renew?? take the bottom hose off its easier

on radiator turn to left open radiator cap

If you are trying to solve an overheating problem this will not achieve anything, but if just to clean out dirty coolant this is how its done..
When engine is cold !!! with radiator in vehicle.
1/ Remove Top and bottom radiator hoses.
2/ Insert garden hose into bottom hose connection of radiator (Use a rag to help seal the connection) turn on water fully to reverse flush radiator till water comes out of top connection, repeat a couple of times.
3/ Reconnect hose to radiator , fill with clean water only.
4/ Run engine till it reaches normal temperature, then switch off engine and allow to cool.
5/ Remove bottom hose to drain system again, refit hose and refill with a good coolant mixture according to you climate.
