Hello my apologies if this has already been posted.
I have a 1997 Firebird Firehawk M6 5.7L LT1.
I would like to know the process to get air out of my cooling system, I do not need to do a coolant change or flush.
My temp gauge has been shooting up into the red randomly when driving and I can hear the coolant gurgling really loud after a shut the engine of and even when I come back from a 15 min drive.
I also see there is coolant spewing out from the front passenger side (could be from overflow, rad cap, waterpump) but I have yet to jack it up and check underneath which I will do later today.
My engine was rebuilt few years back by previous owner and when it was rebuilt they switched it from using dexcool to regular green coolant.
I did get a new delco rad cap which I will use once the air is out.
If i need to replace the thermostat what is the recommended temp I should replace it with?
Thanks!

Re: How to get air out of cooling system
Theoretically the air should work it's way out. Is the radiator and overflow full?

When the thermostat failed on my Hawk, luckily I was not far from home. I replaced it & used this to burp the system. It worked great. https://www.google.com/url?sa=i&rct=j&q ... 6626573573

Thanks for the info.
Looks like my thermostat is shot and needs to be replaced. Just picked up a 180 degree one hoping to change it soon.
Removing the ram air intake to access the thermostat should be be pretty straight forward right?

Yes, easy enough to do, as it hangs off the front of the engine block.

Sorry for the late reply, was a hectic few months.
Update on this issue:
The radiator was low so I filled it up. Started up the car and let it run but this time I had the heater on full blast and once it got warm I saw a leak in the heater hose at the front, it was shooting out coolant towards the lower passenger side. This appears to be the heater hose that is connected to the bottom of the water pump. It's spraying out coolant right in the middle of the metal section of the pipe.
Does anyone have the part number for this hose? I tried to find it on rock auto but was unsuccessful.
I can post a video clip of the leak if that helps.
Thanks again!
