cooling woes
I just did my water pump and it was really easy and the noises I was having went away. The problem is that I am having trouble getting all the air out. When I was done I had left the rad cap off to let all the air out and I had to squeeze the top rad hose. Still some what air locked.
The second problem is that my temp gauge doesn't work, so I had replaced my coolant temp sensor and it didn't change anything. I checked the voltage at the PCM/Ecu and it was reading the right volt for being at operating temp. Is there anything else anyone can think of?
One thing I did notice was that I had installed a 180 thermostat but I was running 195ish at idle(I was using a digital volt meter and using a chart to map what temp I was at).

The few times I've messed with my coolant system (replacing the thermostat, draining the system, and replacing the water pump) I've never had a problem with purging air in the system.
I always would just fill the block up, put the thermostat and upper hose on, and top off the radiator. Sometimes I would run it with the radiator cap off, sometimes I wouldn't.
For the temp gauge- (there are two coolant temp sensors - one for the gauge which has a 1 wire connector and is located on the passenger side of the thermostat housing, and one with a 2 wire connector and is located on the drivers side of the thermostat housing).
I have had issues with my coolant gauge not working, and it was the wire not making good contact with the sensor. With everything connected, try to push down on the wire itself (not the plastic part of the connector).
Also, a quick way to test if the gauge/wiring is good is to short the connector to ground. The gauge should go full hot.
