Is Buick Luzun's rear heater water tank easy to change?

More troublesome! It takes about 3 hours if you are skilled! Remove the rear seat first! Take down the plaque on it! It can be seen that the fan, evaporation box and warm water tank are a whole. Remove the air conditioning pipe and two water pipes under the car! Can be removed as a whole! I hope I can help you with your car problem, and ask the car master. 4S shop professional technician, 10 minutes to solve.
