Overheating. Whats Up?!?!?

[Silver6]

So after a huge fight getting my coolant reservoir out and found no leaks. I still can't figure out why my temp goes up. I blast the heater and it goes down a little and when I stop. Could it be the thermostat? Or a relay of some sort? Are they expensive fixes?

Any help it appreciated.

yea can be or your thermo fan not working or water pump or blocked core in radiator , or air in the system

The thermo fans are working fine from what I can tell. Are they expensive fixes? Are they hard to diagnose or fix?

If it needs a new thermostat it's a few hours labour due to some GM insanity it is positoned on the back of the engine and hard to access.
I'd be checking things like waterflow through radiator before you go and get a new thermostat. Sounds like you had a build up of pressure for some reason which blew the hose off.
Maybe the cap is blocked and doesn't regulate the pressure?

How would I go about doing that? I don't have a lot of money so want to diagnose and hopefully fix what I can.
I thought the hose would rip open as aposed to coming off at the clamp?

The factory clamps lose tension over time as has happend to you and the hose just simply blows off. Worm drive hose clamps are the way to go.

Will be something I look at in the future. Don't want it happening again. Is there way to diagnose the above mentioned possibilities?

take it to a coolent place would of been the first thing i thought of. not ask here. it could be one of a million things. hose leak. thermo. pump. no way of telling.

Check with a Radiator Specialist regarding a full system pressure test. The only way to accurately assess the condition of your cooling system and ancillaries.
