No issues with heat after I did the flush/fill on my car using this tool. Refilling it took all of a few minutes.
More than likely the thermostat is stuck open. |
You would be surprised how few techs actually own vacuum bleeders. At Acura zero techs owned one. They are more common in domestic and euro but even then at my last dealer that was domestic (before I finally got out 2 years ago) out of somewhere between 35-42 techs depending on how many were quitting vs new hires only about 5 of us owned a vacuum filler. 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.
