Overheating !!!!!!!

Overheating !!!!!!!
I drive a 03 g35.
Couple weeks ago i was driving and car was fine until the bearings in my Fan Pulley bracket when out and caused my fan to come of and (destroyed) my radiator.
I replaced
1. Fan
2. Pulley bracket
3. Radiator
But i was still getting overheating and my Car heat was NOT hot neither. I also noticed my lower radiator hose does NOT get Hot but ONLY the top radiator hose gets hot .
So i decided to replace the Thermostat.
After i replaced my thermostat i was still getting overhearting.
I think i may have air pockets?
Any step by step procedures to get air pockets out.
Ever time i look up bleeding instructions for g35 they are all different methods.
I also purchased leslie spill free funnel.
Can anyone help

Turn the car on without the radiator cap, turn heater on full blast, let car warm up a bit, and squeeze the middle of the upper radiator hose till only fluid comes of radiator, and no bubbles come out.
I have found this unversal air bleeding to work on diff makes and models.
Does the lower radiator hose get hot now with a new thermostat?

Yes I would flush out all fluid to make sure nothing is blocking anything in the cooling system.
Generally an easy and cheap way to flush out a system is to turn the car on, heater full blast and have a hose at the radiator filler neck filling it up with the radiator butterfly plug removed from the bottom.
Keep the hose running till you see clear water come out of the bottom.
Once you see clear water coming out put the plug back into the bottom of the radiator and let the engine cool down with the water. Don't drain all the water just plug the radiator and turn the hose off.
Once it's cool you can drain the water and fill with antifreeze.
If you have an actual bleeder valve(sorry haven't worked on this model car in a while)
After new coolant is added, turn the car on and the heater and open the valve a little till coolant starts coming out.
leave it open till coolant comes out of the valve in a steady stream with no air gaps.
Some people say they raise the front of the car up so the valve is higher than everything else.

Can you provide step by step for example on your bleeding method.

I ended just walking home with the car parked at a family member house i was so pissed.
Ive been trying ti bleed for weeks and no change. Lower radiator hose cold, and no heat.
I dont think im bleeding it correctly.
Here is what u do.
1. Pour coolant in spill free funnel
2. Turn car on
3. Heat on high full blast
4. Rev a few times
5.I let it run (i can see air bubbles in funnel)
6. But then funnel overflows with coolant
7. I turn car off and Back to Square 1

Are you sure you don't have a clog in your radiator?
Are you using the right kind of coolant? I've seen some cars gum up their cooling systems by mixing two incompatible types and it looked like Superman's fortress of Solitude in there with all the crystals. My sister's old Passat pretty much got trashed when she did this without knowing any better.
It's possible that your water pump could have damage too which is resulting in weak flow.

When you swapped between different antifeezes, did you do a full system flush with pure water before loading the system up with the new coolant? If not.. this could be the cause of your problems.... The radiator may be gummed up.
How many miles do you have on your car? The electrical cooling fans dying is a common problem on these vehicles and a lot of people have problems bleeding them (mostly do to operator error), but replacing radiators and the fan pulley bracket are not normal.

Oh snap... this very well could be the problem then. When you look into your radiator through the cap wen the motor is stone cold, do you see anything odd in there or chunky/gunky looking?

Flush it using the hose trick I mentioned. You'll be surprised how much gunk comes out.
The lower radiator hose should not get as hot as the top hose. Just warm.
Water pump failure be a possibility as well. Not causing fluid to flow.
With the car on, squeeze the upper radiator hose and have someone rev the engine. You should feel hose surge.
If the hose feels the same when the car is revved compared to not revved. Might be a bad pump.
The car is not losing coolant is it?
