Make sure engine is cold then do the following:
- Open radiator cap
- Start engine
- Once the thermostat opens , air bubbles should come out of the radiator neck
- Wait until air bubbles stops coming out of the neck
- Once the Air bubbles stops from coming out , fill radiator as neccessary
- Replace cap and test drive
- Repeat as neccessary
- Process can take long more than 10 minutes or more depending on how much air is trapped in the system.
It tends to be 525 Grams...Just remember the Honda's have a purge system so if it's overfilled it will expell what it can't handle although you may have to do 20-30 miles with the system on to get it to purge and you will notice a diff in the way the car behave's but dont panic this is normal and the Honda guys used to do this befor the systems had measuing capabilites on them..
On the bottom of the radiator it a purge valve
This is an indication that either the a/c system is over charged or the cooling fan is not working.......
If you mean "purge" the air out of the cooling system, then loosen the top radiator hose at the radiator. Pour coolant mixture into the hose until most of the air is purged and replace.
Trouble code P0441 means: Evaporative Emission System Incorrect Purge Flow
Have you done a rebuild? Is this why your trying to purge the cooling system? Typically you will need to run the vehicle till the temp gauges reads near overheating, then allow the vehicle to nearly cool and remove the radiator cap. This allows air pockets to be pushed through the system. You can also run it to normal operating temperature and slowly crack the radiator cap allowing the system to expell excess pressure.
To bleed air from the cooling system, take off the radiator cap and let the engine run. IF there is no radiator cap(some vehicle manufacturers have done away with them, just add coolant to the overflow tank to the correct level. The cooling system will purge air out on it's own
there should be a little purge valve located on the thermostat housing just crack it open and start your engine and you see antifreeze start to come let it flow for about 30 seconds then close it. That should purge out the air.
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.
The purge unit is located at the condenser.
As soon as the proper amount of coolant is in the system the light should shut off. Be sure to properly purge the cooling system of air. what if light still does not shut off
park your car on a steep hill and let run until you see or hear all the air bubbles come out
