NO HEAT
#4
sounds funny but a few years ago i knocked off my small skinny rubber over flow line that connects to the top of the radiator, thus the radiator was essentially open and i had no heat until i found the small problem, LOL

just changed my heater core. and the box that covers it was cracked during my DIY job. so that could be causing the air in the heater core. I actaully just got back from the junk yard and found a replacement for 50 if i pull it.. So if i change that it will stop leaking cold water and the heat should work... im guessing?

The cold water that is coming from the box you cracked is most likely condensate from running the a/c, and not water from your cooling system. You want to get that taken care of unless it is dripping out under the car which is totally normal.
Like other people have said you have air in the cooling system. It automatically bleeds yourself all you need to do is drive it around until it is warm with the heater running then park it, let it cool a bit, and top of the radiator. repeat this until the fluid level doesn't change

Unfortunately winter is starting to head this way and I'm having a similar problem. The heater will only be warm if the car is moving. Once I stop the air blowing in is cold. Is this the same type of problem that can be fixed with the coolant or is there something else I'm missing.

You can. A small amount of water will not dilute the coolant mixing ratio significantly. If you have to replenish the reservoir on a regular basis, then you have a problem. But, why not add coolant instead of water?

50/50 mix of antifreeze is, well... a bad purchase. It usually cost the same if not more than straight antifreeze. You understand you are paying for half a gallon of water, right? at like $5.00 for a gallon of water???? Get the straight and mix it yourself.

True, if you are adding constantly you have a problem. But I wouldn't recommend to constantly add coolant, if you are adding it all the time, because you don't want a system full of coolant and no water. It needs to have a nice mix of both. Just wanting all to understand that having straight coolant in the system is not good advice.

50/50 mix is what you want to have in there. Coolant is anti-freeze, doesn't work as well for high temperatures. The water is there for the higher temperatures, but doesn't work well for low-temps. Hence the 50/50.
If you're using PURE coolant, you should mix 50% with distilled water.
Or, you could just buy the premixed 50/50 stuff and pour it in all day and all night.

So wrong

Wrong also

the over flow tank is more than just an overflow tank. if all your hoses are free of leaks and the system is air tight the overflow tank will self bleed the system.
as the engine and cooling system gets up to temperature the pressure raises and will force air and coolant through the radiator cap to the overflow tank bleeding the system of air. as your engine starts to fully cool the cooling system pressure lowers and sucks back in coolant from the overflow tank and replaces the volume of air that was pushed out with coolant.
I drain and fill my radiator every year to keep the coolant fresh and I never burp the cooling system. I just keep adding coolant to the over flow tank. after all the air is bled out the overflow tank level will stop going down when the engine fully cools..
to help it bleed better while the engine is cooling off I turn the heat on before I shut the engine off.
