Bleed the Coolant System, air vents? Options

[VavAlephVav]

so I recently did the water pump and while I had it apart I flushed through everything with the lower hose off and into the heater hose that connects to the front of the motor.
but I may not have gotten everything out as I had not yet removed the thermostat or water pump when I flushed it, yet I think I got most of it.
I've filled it up and checked it over the last couple weeks and it's not losing any coolant. yet when I start off down the road about once I've got it revved above 3k I hear a little
noise of the water circulating through the heater core. I still have awesome heat, this thing blasts me out and I have to crack the sunroof even when its 2 degrees outside.

So I wonder if I've just got some air still in the system since the heater core is probably the highest point in it. I read something somewhere that showed two air bleeder cocks in the system and one was right on the heater core connections in the firewall.
but I cant seem to identify them on the car, and I can't find the book I read that in and the other manuals I have don't show them.

Do any of you know where these are? or is it sufficient to just rev the motor up high with the cap off and hope that gets all the air out eventually?

Our coolant system is designed to be self-bleeding, given enough time, but for faster results you can park the car facing slightly uphill, remove the radiator cap, start it up and let it run for a while. Make sure the engine warms up so you can be sure that the thermostat has opened up and is letting all of the coolant circulate.

And while doing so, make sure the coolant reservoir is never below the COLD mark -- you don't want the system sucking up air after it cools down.

So it started to get warmer than the normal mark on the way to work this morning.
pulled over and checked and it was just a little low. but the overflow bottle is full, in fact I can see were its spilling out from the overflow bottles overflow hole and onto my battery tray.
I'm pretty certain that it is not leaking from anywhere else. and I know the water-pump and T'stat are brand new.
I do have a new radiator cap as well, but its a cheapy I got at the local parts place when I first noticed my radiator cap wasn't working a couple months ago.
So it seems that my problem is that the system is Not sucking coolant back into the radiator from the overflow bottle,
and possibly that it is expelling coolant from the radiator at a lower pressure than it should be.

So in order for it to siphon coolant back into the radiator do you guys think it is just a bad radiator cap? (I'll get one from Mr. Toyota this time),
maybe just having the overflow bottle too full effects the proper operation?
Is there anything else I should check, like maybe the overflow tube/cap/hose is not properly sealed anymore?

Internal leak, combustion gases goes inside the cooling system creating pressure and pushing the coolant out thru the overflow bottle.

Is there anyway to pinpoint where it is? Intake manifold or head gasket.
It only looses a quart in two weeks maybe and it seems most of that is coming out the overflow, but wouldn't it still suck back in when it cools off?
I also noticed that didn't have much pressure when I opened the cap while hot

It has to be opened up. It may be a small crack but hard to tell where exactly it is. To verify that there are exhaust gases in the cooling system, https://www.youtube.com/watch?v=1_SIwHMLmkM

Have it professionally diagnosed will be your best option.

Generally if you have a crack in the head gasket between the combustion chamber and a coolant jacket you'd have smoke and hindered performance.

I have noticed once or twice that it seems to have more smoke than I'd think it should. can't say that the performance is down much because I've only had it a short time.
'though I've thought maybe the exhaust sounds a little strange.
I do have a local shop that I used to replace a motor in this Astro van I had before I got the Celica, and they did a good job for a lot less than I would have thought ($600).

should they be able to tell whether it is just the head gasket, or an actual crack in the head before they actually open it up?
or do you just have to wait until it's taken apart to be sure, I know with an aluminum head once its been over heated it's a goner

[VavAlephVav]

So I went down and talked to the guy today. He looked it up and said it pays 8 hours for about $500. which isn't terrible, especially since he knows what he's doing and wont try to fkk me.
and another $150 to send it to the machine shop and they'll resurface it, injector seals, clean the valves up a bit.
I told him I'd bring him a complete head kit with all the gaskets and a new set of bolts, so which do you like?

Felpro kit $90

the felpro is the only one with an actual list of all the gaskets it comes with, but it even says things like turbocharger mounting gasket, supercharger mounting gasket.

I mainly want to be sure its a top quality head gasket that will take a little abuse and not break again.

and what about head bolts, are the $16 ones good enough or do you really need the $35 dollar set on a stock 5s-fe?
