its likley to be the head light censor

Start it up and drive.

that year / series of GM sonoma and s-10 where famous for having clogged heater cores - is temp of hoses going in and out the same ? if not try to flush out ther core, if they are, ck to see if the hot water valve is woking, and finally operation of the doors inside the heater box itself

because something is wrong with the GMC.

Just over half is usually when the fans switch on to cool so this should be correct, when cool check water (low oil will not affect tick over temp) , then moniter it if no water loss then dont worry.

the entire dash assembly must be removed from the vehicle to change the heater core

Usually the whole hvac box has to come out of the vehicle to replace the heater core. Once the box is out it can be opened and the heater core removed. Be careful with all the vent doors and actuators, make note of how everything came apart. The last thing you want to do is have to remove the dash and box because something wasn't on just right. Good luck.

If you are mechanically inclined then you should be able to handle it. But if this is the first one you've ever attempted you will need a manual. It will show the tips and tricks to getting it right the first time. As for the tools, you don't need a master set but you do need a standard set of some type. Similar to a 300 piece craftsman set. If you don't have the tools it would be less costly to take it somewhere.
Good luck.
