I was wondering what is the proper way to bleed a coolant? I see way to many videos and tutorials in YouTube about how to perform bleeding in my cooling system.
Do you
have the same problem?

If there is no bleed valve then the best way is to either jack up under the frame on the side where the radiator cap is until the radiator filler neck is higher than the rest of the cooling system which includes the heater core.
Or just pull that side up onto a curb. Then remove the radiator cap, top off the coolant, place a drain pan under the filler, start the engine, place the heater on hot, leave the blower fan off, rev the engine to 1,500 to 2,000 rpm's until the thermostat opens. Then top off the coolant if need be. Then while the engine is idling, grab the top radiator hose in both hands push down as far as it will go without pushing it into anything moving, like the fan, then squeeze real hard with both hands on the hose and push any air out the radiator filler neck, top off coolant again, replace cap, shut off engine and/or lower vehicle to ground.
If though there is a degas bottle, they are supposed to bleed the system themselves.

Thanks for the reply. There is bleed valve located just right above the reservoir next to the cap. What is the best way to do bleed it using the reservoir? See picture attached.

Hi. Thanks for the reply. I am a bit confused with one of the instruction (c). It says I need to disconnect two hoses and place them on the air cleaner case. Is that mean I disconnect two hoses away from the reservoir? And if so, which of the two hoses that needs to be disconnected? I see three hose. One from the bottom of the reservoir and two from top side of the reservoir. Thanks.

I was a bit confused also when I was reading that and as far as I can tell they wanted you to unbolt the coolant reservoir than lift it up and affix it to the hood latch. I assume this is to get the reservoir higher than the rest of the cooling system so the air will rise to the top (the reservoir).
Now about them hoses in C, I assume they mean getting them hoses free as if they were secured somehow, but I don't think they actually mean disconnect any hose cause coolant would leak out, although I could be wrong.
If it were me I would just jack up that side where the reservoir is or pull that side up on a curb and then follow the rest, which includes removing the bleeder plug.
