xart23x: How long are you supposed to do this? Til fan turns on?

Jim Main: Hi Eric. All of your videos are great but there is a lot easier way to bleed the cooling system on a car.
Remove the radiator cap and fill to top with coolant mix. Make sure the reservoir is at full level (this is important when you put the cap back on so air does not get sucked back into the system.
Put the heater on max heat and no fan like you say.
Start the engine. Rev the engine while standing near the open radiator top so you can see when the level drops and air bubbles pop to the surface. Add coolant and keep it to the very top of the radiator.
The coolant level may drop some as the air is expelled from the radiator top where the cap goes. Keep filling it to the top as it bubbles and make sure it is topped off at all times.
Eventually, you will see coolant flowing fast at the top of the radiator as the thermostat opens. You can rev the engine a few times and some more bubbles may pop to the surface of the coolant in the radiator.
When all bubbling stops for 4 minutes and you can see the coolant is flowing (swirling), the air is gone.
Make sure the radiator is full the top, replace the cap, and top off the reservoir if it has dropped.
I have done it this way since I first started working on cars of all types.
I am 100% sure it works. On the latest car I did, air bubbles were going from the radiator into the reservoir while the engine was idling. Heat was also weak. I had replaced the water pump and the thermostat. Once I did my procedure, all air bubbles going into the reservoir stopped showing there was no air in the system. Heat is as hot as it should be.
IMPORTANT - While the coolant is not under pressure, it can splash from the air bubbles or when the thermostat opens so make sure you are not in a position where it can splash on you or in your face. Safety first.

Amanda Owen: my fans never kick on until the car is off

Lino Acuna: well when I first got the car it ran great then it started bubbling up.I bought a new head gasket my mechanic changed it out so he says.car ran great for about a whole year then it started slowly over heating changed out the water pump thermostat. new coolant new radiator new cap.ran great for a few months car still runs great just dam resivor sucks up the coolant fast til there nothing but steam coming out of it or the coolant bubbling hot!!!! so am thinking this asshole probly never changed out the gasket or my head is cracked or a big air pocket is in the system

유종민: Got a P0125 code (Insufficient Coolant Temperature For Closed Loop Fuel Control). I constantly needed to add coolant, no heat and the car overheated during idle and runs at high temp (225F+) during acceleration. I added a sealant, the coolant leaks stopped but now the car overheats at idle but cools down (180F) when I press on gas. Still don't have no heat at idle. Do just need to burp the cooling system?

alex luevano: hey eric i have a 00 gsr with a b18c does it have the bleeder valve in the same place?
