Cooling issue

[Funkybird]

Ok, here's my dillema. My cluster temp gauge has been acting up the last few weeks so I went ahead and installed a scan gauge to see if the pcm was getting roughly the same reading and they were completely different. I have been ignoring the cluster gauge but lately it has been getting hot so today I let it idle and the fans turn on when they are suppose to.
The thermostat is a 160 and I did have it out of the car earlier this summer and boiled it just for the hell of it and it was fine. Other then that I haven't messed with the cooling system all summer so unless an air bubble just appeared for no reason that shouldn't be an issue.
I have a custom radiator from OFI and 2 spal fans that are less than a year old.
When the car got hot only two radiator hoses were hot too. THe upper hose that goes to the t-stat and the small d.s. 90* fitting that goes to the lower d.s. radiator were hot and the rest were cold.
What do you guys think? I will try and bleed it but I wonder if the water pump has taken a shit hence no circulation and some hoses still cold? It isn't leaking out the weap hole and it isn't squealing.

If you're getting differentiating readings between the gauge and PCM sensors, change the gauge sensor first. Those get finicky at times.

You know there are two temp sensor. The one that is on the driver side block by spark plug #1 controls the temp gage in the car. The other is in front of the water pump which controls the fans, and pcm readings. I had the one on the block fail which gave me false readings. Once replace with a new oem unit the readings were close to what the pcm sensor reading.

I'm aware there are two different sensors, I replaced the sending unit in the head and tested the gauge/wiring circuit and all is well there but the problem is still there.
I just went to bleed it and there was no coolant in the upper hose to bleed and the whole time it ran it just blew steam out the hole. WTF?

Well either you dident properly bleed it before OR the coolant is going somewhere (IE head gasket burning it off, leaking somewhere ect..).

Try filling it up with the 50/50 mix and bleeding it again. Get it bled correctly and drive it, making sure ALL the hoses are HOT and full of coolant. If it does the same thing (leaks to nowhere) you might have a headgasket on your hands.

The gauge could be off because sometimes the sender has coolant on it, and sometimes it doesnt. Making the readings fluctuate wildly. Ive seen large air pockets do the same thing, even when it appears to be bled perfectly.

I'm not loosing any coolant. It just seems to be not circulating and/or have a big ass air pocket. I'll try bleeding it a few more times.
