Bleeding coolant bleed a new radiator

Did you bleed the air from the radiator and coolant system? Every manufacturer has their own method for bleeding the cooling system as most are sealed units and they bleed themselves when topping off but not after a radiator replacement or complete flush. You must follow manufacturer coolant bleed specs....also did you test the new thermostat? I've noticed one out of 8 new ones don't work. Best to test in a pot of boiling water 3 times before installing to avoid the headache. I've learned the hard way. It's time-consuming to check it before less time-consuming than having to take it out and troubleshoot a million other things all because of the bad new thermostat.

remove header tank cap undo drain plug at bottom of radiator and bleed screw at top of radiator once all coolant has drained retighten tthe drain plug pour the new coolant into the header tank waiting for the coolant to drain through system and watch for coolant to come out of the bleed screw , shut bleed screw top up the header tank to the max level replace cap.Now run engine ,dont drive just stay with revs at 1500 open bleed screw to let any trapped air out and wait for the cooling fan to cut in , allow engine to cool down and refill header tank if required and repeat the running/bleeding/fancutting in procedure until when engine has cooled the coolant is near the max mark on header tank

just keep bleeding the air out. unless you have a blown head gasket or cracked head, there is no way for the air to get in there accept for the work you have done. you can get a fitting that will screw in to the bleed port and hook a hose on it, stick the end of the hose in a jug half full of coolant and start the car let it idle you will see the bubbles coming out let it run with out the radiator cap on when it starts filling the jug with coolantwhen you dont see any bubbles put the cap on and kill the car. Replace the bleed plug and fill the radiator back full , make sure the over flow tank is full of coolant start the car let it run it will get rid of any other air and push it in the overflow tank and when it cools off it will suck the coolant back to the radiator.

Was the thermostat changed? I would suggest replacing the thermostat refill the system with new coolant and purge the air out of the system.

there should be a plug (small bolt) at the thermostat housing remove it while filling the radiator. replace it when coolant runs out without air pockets

Hi,
The bleeding nipple would be near the water pump rad hose inlet and beneath the thermostat valve cover.
Bleeding is easy, just fill up the radiator and the reservoir w/ coolant run the engine for 5 min and open the bleeding nipples! or Just fill up the radiator before u start the engine, early morning, run the engine for 5 min. untill the thermostat valve opens, open the radiator cap( use a wet rag ), carefull not to open it instantly! Fill up the radiator while the engine runs, add coolant while u slightly reving up the engine.
Do these and open the heater to maximum, air might be inside the core too!
Hope that helps u out!

BLEED AIR OUT COOLANT SYSTEM.WAIT UNTIL ENGINE COOL DOWN.REMOVE COOLANT OVER FLOW PRESSURE CAP.IF YOU HAVE 3.1 OR 3.4 ENGINE OPEN AIR BLEED SCREW ON WATER PUMP BYPASS HOSE.OPEN BLEED SCREW.WATCH COOLANT IN OVER FLOW AS YOU OPEN BLEED SCREW COOLANT WILL DROP IN OVER FLOW JUG. AS IT DROPS CLOSE BLEED SCREW ADD MORE COOLANT IN OVER FLOW JUG DO THIS UNTIL COOLANT LEVEL STAY AT COLD FULL MARK.WHEN DONE TIGHTEN BLEED SCREW DONT OVER TIGHTEN IT OR IT WILL STRIP OUT BREAK.CRANK CAR UP UNTIL THERMOSTAT OPEN THAT WHEN TOP RADIATOR HOSE GET HOT.WATCH COOLANT GAUGE,IF ENGINE TEMPERATURE RISES TURN OFF ENGINE WAIT UNTIL COOL.REMOVE RADIATOR PRESSURE CAP USING A RAG TO KEEP FROM GETTING HANDS SCALED.ADD MORE COOLANT IF NEEDED WHEN ENGINE COOLANT STOP DROPPING IN OVER FLOW JUG AND ENGINE DONT OVER HEAT AIR IS OUT OF COOLANT SYSTEM.

The reservoir is the traditional top tank of your radiator.

The answer to your question is yes.

1. Fill the coolant in the coolant expansion tank
2. Ensure that no coolant leaks from the radiator and pump
3. Identify the coolant bleed screw, this screw is just beside the thermostat
4. Start the engine and loosen the coolant bleed screw. Now coolant comes out with air bubbles. allow the coolant to flow until coolant comes without air bubbles.
5. Tighten the coolant bleed screw.
