Today while i was doing coolant change, i only manage to get about 1gallon and a 1quart out of the radiator through peacock. I had the car idle for 45minute while squeezing the upper and lower radiator hose and even rev alittle. The radiator fan came on at least 5 times in the process but I could only put back 1 gallon of new coolant. Am i missing something?

oh almost forgot to mention for some reason having heater on max, air vent air sometime is hot sometimes is not.

 

I just did a half flush on my v6 Mustang and our Edge v6 by undoing the bottom radiator hose. Both took a gallon and a half to refill. I'm afraid you have gotten a lot of air in your cooling system I had to help someone who got a lot of air in their cooling system. I had him pull up on a hill with the front as high as we could get it. Took the cap off and filled with coolant as needed. It blew bubbles and cough for an hour or so. This worked for him, might not for you. I'm a hillbilly from Tennessee and we do strange things . I see your from Florida and might not have any hills

 

Thanks for the reply, im about 3/4 of quart short than what i drained. Ive been doing alot of reading seems i need to take it out for a drive like 15 minutes or so for the coolant to circulate. So i might try that tomorrow if it doesnt rain. Oh i moved to NY last year but yea no hills around here.

 

The cooling system is easy enough to bleed. Next time you start the engine cold, remove the pressure cap on the expansion reservoir while the engine's idling with the heater on MAX and top it up. After a couple of drive cycles the system should be properly bled and you can do a final top up.

 

I know you know to put the heater on all the way to hot and the fan on high when you do this, but it's easy to forget

 

This morning when i went to check my coolant level it was the same but what was surprising was as i open the cap it release a great amount of air suction. The level from max dropped down to min. I also took it out for a spin and will be checking the levels again tonight or tomorrow once its cooled down. The air vent was hot the whole time during drive too. I think i did it but probably need to change my coolant couple times every 6month or so to get the last 2 gallons of old coolant out.
