I recently had my car's engine replaced with a rebuilt engine because of a blown cylinder. Since I got the car back, the engine light came on and I discovered there was no coolant in the radiator..the mechanic says my car now needs a new radiator fan? I'm not sure what he's talking about.
The need of a coolant fan replacement, should not cause you to be low on coolant. You coolant system is a closed system, meaning if it is extremely low or EMPTY there is a leak. All vehicles have a cooling fan to increase air flow on maintain the block temperature.
Hope this Helps
If the radiator was empty, the vehicle should have overheated. You need to see what the code was so that you know why the check engine light came on. It's possible that the coolant was low and you just couldn't see it when you opened the radiator.
As for the fan, I'm not sure why they are telling you that you need a new one. Ask why. Is it possible that they damaged it when they installed the engine? They either run with a belt or electricity. Find out why they feel it needs to be replaced.
