The starter service doesn’t require removing any cooling line. You do need to move the radiator shroud down a little and your clear. Everything can be disconnected under the car and removing the lower bolt. Then, the top bolt comes off and bam.. your golden. Reinstall. It is a easy job. No clue how the tech messed up.
It is very possible that the tech instead did this: he removed the radiator shroud and took the whole shroud off of the car just to get to the starter. This can very much cause you to lose some coolant because the shroud has the expansion tank built in. If you remove the shroud you can leak from expansion tank, hence, loosing some coolant. An overblown situation is what I would call it. However, if they put tap in the car, remove the expansion tank (assuming they put it there) fluid and fill back with factory 50/50. But! If you have already ran the car thru 2 or more heat cycles, you already mixed the tap water in the system.
So many sloppy Joes.
