How is reverse flushing of a cooling system done?
Reverse flushing of the cooling system is the forcing of water through the cooling system. This is done using air pressure in the opposite direction of normal coolant flow. It is usually only necessary with very dirty systems with evidence of partial plugging.
What happens when you flush the coolant bottle?
If the engine cooling system overheats and pushes coolant into the overflow side of the coolant bottle, this coolant will be sucked back into the cooling system ONLY IF THE PRESSURE CAP IS LEFT ON THE BOTTLE. Removing the pressure cap breaks the vacuum path between the two bottle sections and the coolant will not return to cooling system.
How often should you flush and refill a radiator?
The irony is that many new radiators do n ot outlast the long life coolant!! If you do a drain and refill every 3-5 years, you will never need to flush the system. Flushing actually increases the potential for contaminants in the system.
What’s the best way to flush a car cooling system?
Step 5: Fill distilled water. Once all the coolant is drained, close the petcock and fill the cooling system with plain, distilled water. Replace the radiator cap, start the engine, and run the vehicle for about 5 minutes. Step 6: Check the system pressure.
How do you flush and re-fill coolant?
Fill the funnel until water is built up within the funnel then start the engine. Water will be sucked into the radiator so add more water to fill it up until the level no longer drops. Stop the engine. Fill the reservoir with demineralised water as well.

What happens when you flush your car cooling system?
After it cools down, start the vehicle again and continue to let the air bleed out of the cooling system. When all of the air is out, the heater will blow strong and hot. When you touch the lower and upper radiator hoses, they will have a similar temperature.
When to drain and refill a fully sealed cooling system?
Coolant which has expanded as the system warms up passes down the tube into this tank, and is drawn back into the radiator when it has cooled. The system is supposed to be maintenance-free, and is drained only when a hose or the coolant is due for replacement.
