Bled system 2 days low reservoir
 

I got a new radiator and bled the system. Was quite a bit of air in it. My question is I’m super low on coolant in my reservoir 2 days in a row after bleeding. I actually bled it the night I put the radiator in , drove it an hour. Was low in the reservoir the next day and I bled it one more time. So today after driving and letting it rest there was very low coolant to the bottom. Is this normal given all the air that was replaced with coolant. How many days can this go for. I’m almsot thru a second gallon of coolant.

If you have no leaks, continue topping off the reservoir as needed. I would give it a couple of weeks for all the air bubbles to be flushed out of the engine.

?
 

but didn’t I already bleed the air bubbles out ? How would anymore continue to get out if I have no leak ?

Evidently not. I saw your other thread regarding the bleed screw. That will only remove air trapped in that chamber when you open the bleed screw. Air can still be trapped throughout the cooling system and it can take time for all the air to be pushed out.

Matter of fact, I have never used the bleed screw. I find it too messy. I use a Lisle funnel kit on my vehicles to bleed the air out. It gets most of the air out when you refill the radiator and run the engine until the thermostat opens. After that, I top off the reservoir as needed. Usually over a couple of weeks every 2-3 days or so. And it takes very little coolant to top off. Maybe a cup, total.

I use the Car Care Nut's procedure and don't need to top off the reservoir at all. You may not be following the procedure correctly, or, you may have a leak, or a possible head gasket issue.

When you follow the bleeding procedure, do you run the engine for 10 minutes or so at 2,500 rpm, with the bleed screw open and the bleed hose running back into the bleed funnel? CCN says to keep the engine running at that rpm until no more bubbles emerge from the bleed valve. That's why he calls for a clear 1/4" bleed hose...so you can see any bubbles. To keep the engine at 2,500 rpm, I use an adjustable device that hooks to the steering wheel and presses on the gas pedal.

I did exactly that
 

only difference is I was intneh car accelerating to 1800 and I had the clear tubing going up top of the hood until I saw it going straight fluid no bubbles and up took around 5-10 minutes before that happened. Saw the fluid go high in the funnel and then start to lower, so if tomorrow I’m still low on fluid I’ll know soemthing is up. Maybe a head gasket issue hope not

Top off reservoir
 

many people have said on here when you do this procedure and have any air in the system that you get out thst air is replaced by liquid so inherently you will need to top off your reservoir when the engine cools back down also tho right ? That’s the whole reason for the procedure. If you had no air maybe you won’t have to top it off correct ?

Yes, using the CCN procedure, there is no air left in the system, so no topping-off of the reservoir is required.

However, if you have a leak, or if you cut corners on the procedure and didn't get all the air out, you will have to top off. But needing to top off indicates air was trapped in the system after re-filling it. And, as stated earlier, trapped air can cause severe engine damage that may not show up immediately. Years later you might have a head gasket failure due to the the head gasket being "spot-cooked."
