cel: coolant circuit low input
 

Some idiotic car shop did a coolant and radiator flush/swap. I didn't really check assuming they could perform this task. However they filled the coolant reservoir to the tip top and the coolant spilled all over the engine bay. I didn't notice until i saw smoke coming out of my hood. Before I could park to the side the car threw a CEL. I checked it with the AP and it says that the cel is from the coolant circuit: low input. Does anybody know what does this mean and hwo to fix it. I am going to flush and swap coolant myself on my day off.

shouldn't be too big of a deal. let it warm up and evaporate. clean the engine bay. maybe use air instead of water at first.

not sure about the cel. probably not a big deal either.
