I have a coolant problem that's been puzzling me:
I recently had my mechanic change my thermostat and radiator hoses. They also added more coolant since all of mine escaped through a damaged radiator hose.
The other day, i checked my coolant level in the overflow tank and noticed that it was dry (i checked on a hot and cold engine, however, there was plenty of coolant when i opened up the radiator cap).
Does anyone have any suggestions as to what maybe causing the overflow tank to be dry? Should i check if there is a block in the system or a pocket of air? Thanks!
