take fill cap off run engine this will run it though the system. if the system needs more coolant or had air pockets in it this will make it burp
Bad coolant concentration/leve. Most likely has bubbles in the head. Google "burp 240sx" and follow the instructions.
I can generally do it by forcefully squeezing the upper radiator hose several times with both hands.
Fill the vehicle with coolant and leave the filler cap off. Start the vehicle and keep adding fluid as the coolant level drops. When the motor is warm enough for the thermostat to open up you will see the coolant level drop quickly. Put in more coolant until it is full then shut off the motor and put the filler cap back on.
You carefully remove the top coolant hose to the heater, not totally off, just enough so air can get out.
Open the radiator cap and pour coolant in. If you're filling an empty system, you'll want to leave the cap off, and run the engine for 30 minutes or so to 'burp' out any air in the system, then top your coolant off again.
low coolant level check for leak and repair add new coolant and burp the system to get all the air out and make sure thermostat is working properly
Fill the coolant, leave the cap off. Start the engine, turn the heat on high. Keep the engine revved to about 2000 RPMs (I use a hood prop for this). The engine will heat up, open up the thermostat, circulate the coolant, and burp out the air. You may have to repeat this process a couple times. Me, personally, I just use a vacuum refiller to refill the coolant, and it eliminates the need for burping. But they're very expensive and require an air compressor.
you might need a machine but what i do is disconnect a big hose from the raddiator thendrain into a pan refill and burp all the air out
do goats burp
you burp, as you are burping make your mouth move as if you were saying a letter
Sometimes you can't burp because you never did something to do something to burp. If you would like to burp try drinking coke. Could be any any coke. The normal coca cola, diet coke you name it! If it doesn't work try to ask questions on how to burp in lots of different ways. For example How to burp? Or How can I burp? Or How do you burp?
You burp right from the start.
