I just had to replace a split coolant hose that I'm gonna guess cost me atleast 50% of system capacity and now comes refilling and burping of said system. How do I go about burping the system to get all the air out of it so I can hopefully avoid an overheating issue?

------------------
4,500 RPM in 5th gear is bad?

Basically pour antifreeze in slowly at the radiator and thermostat housing until full. Replace the cap(s) with the thermostat removed start engine let it run for about five minutes, shut off engine, come back in about an hour remove thermostat cap, top up antifreeze as necessary, install the thermostat back in. Drive away

way too long!
remove radiator cap, fill from tstat with tstat removed till radiator is topped, the cap the radiator. continue to fill till tstat is topped off, put on cap, but no tstat. start car for 30 seconds. shut off, remove tstat cap and top off, replace cap. start car and rev the motor a few times, 3-4krange is fine. shut off, top off at tstat, replace tstat, cap off, fill reserviour to cold line + a smidge more. check it in a few days after driving.

What tjm4fun said is the method I use, and have had exellent success. Except I dont use the 3-4K rpm part, as the engine is usually running at a fast rpm because it is cold.

Nifty, when filling from tstat til radiator is full would it help if the back end of the car is elevated (jack/ramps/steep driveway) putting the radiator below the tstat to more or less force coolant down the lines to the radiator?

That is awesome pontiackid, I'm gonna have to pick me up a funnel like that.

I finally got the system burped using the first method mentioned, but I will def use the faster method in the future.

Thank you for the advice ya'll.

you don;t need to raise the car. it doesn;t help. ( a while back I posted a drawing based on the side view of the car, and you can see how you would need to put the rear almost 6' in the air before you would be able to overcome the ups and downs of the coolant lines. Bein basically lazy, I always opt for the simple methods ) running the motor without the stat in allows the circulator pump to move the air around, and air will always rise tot he high spot, the tstat housing and the heater core. if the system is fully empty, you should probably do the run part 3 times, or until the fluid barely drops.
