- During tune up, the cooling system may have been opened resulting in loss of coolant.If any leaks were present before, they could worsen in the absence of coolant.
- The tune up might have caused a mechanical issue that caused a loss of coolant in the car, like damaging a hose or the water pump.
- The air conditioning system may have been overcharged, which could create pressure in the cooling system and cause coolant to be pushed out.
- There might be a leak in the cooling system that may have been overlooked or exacerbated by the temperature changes when the A/C was filled and the tune up performed.
- It is possible that a radiator cap or hose clamp was left loose after the tune-up, which could allow coolant to escape.
It's important to take your car back to the mechanic or the auto shop that performed the tune-up and A/C refill to have them diagnose the issue and make any necessary repairs. They should check for leaks in the cooling system, test the integrity of the cooling components, and ensure that everything is properly sealed.
