How much coolant is required to fill the system after flushing the entire system?

two liquids regulate temperature i the car - oil and coolant. you need to check both, as you did not bother to think and provide us with manufacturer,model, fuel type and year, only general info can be provided.

oil - check level and change/top up as required, if change required - change oil filter as well while you are at it. change for type of oil required for your vehicle, oil and filters should be changed every 5000km (3500miles) to 10000km (7000miles), this depend on the condition, driving and age of the engine.

coolant - check level, top up f required.

if oil level is correct, and no loss in coolant either, you need to check coolant flow, start investigation if pump belt is not too lose and tension it if required, cannot do that if pump is driven directly from the shaft. check for thermostat problem and change if required, lastly - check radiator flow and reverse flush if required.

if you are flushing radiator - best is to flush block and heating system as well at same time, drain liquid and re-fill with new coolant.

hope this will help you at least a bit - do not forget to vote... :-)

Several possibilities. If you have just had your engine coolant flushed the heater core could be filled with air preventing circulation of warm coolant. Requires bleeding of excess air from system. Search for the details for your car model. The cable controlling the heater valve may be broken, the heater core may be clogged and require a reverse flush to clean it. Heater hose could be kinked.

1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary

You need to drain the old antifreeze and flush the entire cooling system with a commercial product such as Prestone Super Flush. After flushing according to the directions on the product you will want to fill the cooling sysstem with plain water and let it circulate through the system. Drain the system again and repeat the process until the water is clear of any antifreeze. Refill the system with the proper mixture of antifreeze. Make sure you use a quality antifreeze that is compatible with your make and model of car. The auto parts store personnel can help you select the right antifreeze. DO NOT refill it with Dexcool. That is the antifreeze that GM put in originally that is causing the problems. Dexcool not only forms a gummy sludge in the cooling system, it also attacks certain gasket materials and causes coolant to leak into the engine. Hopefully, this hasn't happened yet.

On your MPV engine coolant total.

Without rear heater total coolant 10.4 qts.

With rear heater total coolant 12.3 qts.

take of the top heater hose, use a funnel to insert flushing agent connect hose and flush through.with radiator cap off.take off bottom hose to radiator to drain system,reconnect all hoses,fill expansion tank to fill system...

replace radiator, the trany cooler which is part of radiator is leaking inside radiator, flush cooling system after replacing rad, also i would flush trany also to be 100% sure that theres no coolant in that oil, hope this is helpful,

Slap on those vinyl gloves because the ethylene glycol in antifreeze can cause skin damage - however we recommend this because the antifreeze feels like engine oil.With your catch pan in place, remove the radiator drain plug and collect all old coolant. Immediately dispose of the coolant as required by environmental laws - if you are to surrender the old coolant at a waste management facility, be sure you use containers which can be properly sealed to avoid spillage, etc.To expedite the draining process, remove your radiator fill cap to allow air to enter the system.
Also be sure to remove all coolant from your radiator reservoir. We suggest you use the gravity siphon trick - just be sure not to ingest any coolant.

Watch the old coolant as it exits the system - this will give you a good idea of your vehicle's cooling system condition.If you see metal flakes, oily surface, white flakes, etc .. you can make a diagnosis of your engine's coolant system.
Essentially, if you see anything but coolant and some very minor debris, it can indicate the early signs of cooling system failure.When all coolant has been drained from the radiator, replace the radiator drain plug and then fill the system with plain tap water to dilute remaining antifreeze in the engine block.
With the cooling system refilled with tap water, replace the radiator fill cap and run the engine allowing it to reach operating temperature.When the engine's cooling fan turns on, it is an indication that the vehicle's thermostat has opened, allowing the freshly added water to circulate through the engine thus diluting the remaining coolant. Allow the engine to run for a few minutes before shutting it off.
At this point, you can either wait until the engine cools off, or take fate in your own hands and continue the flushing process.Repeat the draining process being sure to once again collect and dispose of all waste coolant.
At this point, if you have opted to purchase a radiator flush kit, you should refill the cooling system with tap water and add the caustic fluid as directed.
Run the engine for as long as the radiator flush kit calls for (usually less than 10 minutes).

Once again, drain the cooling system, collecting all waste fluid. This is the last time you will be required to collect engine coolant during this process.Now that the cooling system is empty, replace the radiator drain plug and refill the cooling system with distilled water only. The reason that you should only use distilled water at this point is to avoid mineral deposits which will deteriorate your cooling system over time.
Once the cooling system has been completely filled, start the engine to allow the water to circulate. Once again remove the radiator drain plug. As the engine runs, pour fresh distilled water into the radiator fill hole at the same rate that it exits the system.Continue this process until the water being drained from the radiator appears to be clear and free of debris. Once you are satisfied with the drain water's appearance, stop the engine and allow all remaining water to drain out.Replace the radiator drain plug and prepare to mix your distilled water and coolant.
Be sure to mix your coolant to the ratio recommended by your manufacturer. In most cases, the ratio is 50% distilled water and 50% coolant.
As a tip, mix the coolant and water in a third container being sure to observe the proper ratio.As you mix your water and coolant, use your hydrometer to measure the specific gravity - this will give you a good idea of whether or not you are mixing the coolant and water properly.
Once you have mixed enough coolant and water to fill your engine's coolant system entirely, grab a funnel and place it in the radiator fill hole.Fill your radiator at a rate of no more than:
{ 1 L/min. \ 1.1 US qt./min. \ 0.9 Imp. qt./min. }.
Continue the filling process until the coolant reaches the bottom of the fill neck. Now fill the radiator reservoir to the full mark.
With the radiator fill cap still off, start the car and allow it to idle. As the engine runs, continue to add coolant as air escapes the engine and cooling system.As you top up the radiator, be sure to "burp" the cooling system by firmly squeezing the radiator hoses (both upper and lower). Continue to squeeze and release the hoses to help push any errant air bubbles out of the system.
Once you are unable to fill the radiator any further, replace the radiator fill cap and stop the engine - you are finished.

Power flushing is usually not a good thing as the heater cores can become blocked.I would suggest to remove the lower rad hose and drain as much coolant as possible.Refill with clear water with lower hose reattached.Bleed system of air as you fill with water and keep filling until operating temp is reached.Drive and return and drain it again the same way,now refill with at least 1 and 1/2 gallons of dexcool and don't forget to add the vegetable based aluminum protector required in your vehicle available from gm and make sure you bleed the air from the system from the valve just to the rear of the rad filler neck on the engine at the end of the coolant pipe running across the front of the engine.
