Most don’t even own a coolant system pressure test kit. Dealers today mostly hire at low wage at flat rate and those tools aren’t cheap. We had a corvette come back 3 times for overheating after a service because they didn’t use a vacuum filler and air got trapped in the crossover piping before it finally got sent over to us drivability guys to fix it.
