Volkswagen Mechananic

The dealership told me i need a new water pump. My 2016 golf overheated when the air was on high. It does not do it if the air is off and I have not turned it on high again. I am looking for a reputable Volkswagen mechanic close to DC. Thank you for the recommendation.

It doesn’t overheat with the A/C turned off because it can still move enough coolant (even at diminished capacity) through the radiator to keep engine temps below the overheat threshold.

But when you add in the extra thermal load of the A/C evaporator coil when the A/C is running, the radiator can no longer shed enough heat to keep engine temps down.

Your water pump is failing. I’m guessing you have the 1.8L turbo? Any severe overheating will warp your cylinder heads within minutes. That’s a totaled engine.

Thank you for the information. I will get a new water pump.

BTW, it's not a turbo.
