We had the coolant changed and the first couple of days it was ok meaning no coolant on garage floor. He drove it to work and on return trip-it gushed coolant out from where we do not know. One thing we did observe is that the reservoir reading is hot level even when cold.
Where is the coolant comming from?
 
take radiator cap off..[not the overflow plastic thing] run it with heat on.[to add heater core to system]..add coolant [50/50] as it burps.....if no joy think thermostate replacement...
 
There is too much coolant in the system and the burping was caused by the expelling of air in the system. Both are indications of the wrong procedure used to fill your coolant. I suggest to take your vehicle immediately back to the garage and have them correct fluid level, the air has most likely purged by now. In addition, demand that they do a coolant pressure check to ensure no leaks in system.
 
Seriously overfilled the coolant, it sounds like to me.

This will continue happening until the coolant is no longer so over-full that it spills out when hot.

The first couple of days, my bet is you didn't drive the truck as far as you did on the third day-- at which point it heated up, the coolant expanded, and "burped" it out all over your garage floor. I'd be willing to bet it was also leaving a trail of coolant behind your man while he was driving down the road, as well.

Pay close attention the to S-10s temperature gauge, if it has one. If you get a coolant or engine temperature warning light, you need to park it and let it cool down. After that, I'd be getting it looked at by a trusted mechanic-- preferably not the same one who did your coolant change.

EDIT: Pedro, you made a good point. Could have some air bubbles in the radiator tubing. But to do that procedure, make sure you wait until the engine is dead cold before removing the radiator cap-- else you might get a "burp" of scalding hot coolant all over you...or at least a burnt hand. If you do this, remove the overflow jug lid, as well and be prepared to have an over-full coolant system anyway.
