I would be surprised that you overloaded the coolant pump, unless it is the high pressure type, most are centrifugal pumps, and even if you block the pump outlet, that actually reduces the current.
Anyhow, the fuse or overload is going to be in the main panel. It may be just the overload tripped which is on the coolant pump contactor.
You should at least have service manuals or schematics, this make for much easier servicing.
If factory fitted, there will be a designation label that identifies the contactor and O/L.
