Heating in the car stays cold - just clean it yourself

Hello,

For the cold winter season, I recommend with cold heating, if the controller is on "heat" and not really hot is the following thing:

Crush 3 to 4 dishwasher tablets to a powdered form with a knife, drain a hose in the car, clean with it, fill with water and drive for 5 days. I recommend driving on the highway or driving in the higher speed range, so the pump pumps more water, also through the heater.

The whole brown smear salad dissolves with it. Drain the water again and rinse the entire system with a garden hose. It is also best to flush the heat exchanger directly. The brown sauce is all the oxide that composes the exchanger.

Workshops completely disconnect the heat exchanger and fill the heat exchanger completely with 25% ethyl acetate. Leave the case for a day and rinse the next day.
