Purging air from cooling system.

[opus69]

JFP is right. I did the burping technique but have only managed to get 4 gallons into the system leaving me to believe there may be air still in the system. I am fairly certain I completely drained the system but likely did not since the amount captured when draining was between 4 and 5 gallons. I replaced the lower radiator hoses and installed a new low temp thermostat. Thought all fluid was out but perhaps not.

I thought I had a link, but couldn't seem to find it. There is another 1/2 gallon of coolant still in the system that canot be removed simply by removing a hose. It's in the heater core. To remove it, you need to find the two lines form the heater core and use compressed air at low pressure to the top hose. This will blow out the remaing 1/2 gallon.

Personally, if you flushged your system with disctilled water as I did, I wouldn't worry about it. Same if you used the same type of coolant for the fill.

I've done it Eric's method since 04.. lol The lift system works great, but I have NEVER (ever) had a car overheat. Paranoid? Buy the lift system.

The system is self burping. The two lines from the top of the radiator go into the top of the reservoir and bleed air into it.

Fill it up. Warm it up, drive it. Carry a jug of distilled water with you. Top it off up to where the white plastic meets the black plastic (look down into the reservoir)
