If the WW temperature in Peugeot 207 is often increased to more than 90 degrees, it is necessary to radiate the heat sink before you start troubleshooting. With little contamination, the engine cooling radiator can be cleaned at the car wash without taking off the bumper. At the same time, using a high pressure tile, you have to be very careful, because there is a risk to damage the heat exchanger. In addition, after such cleaning or flushing, the space between the engine cooling radiator and the air conditioner will remain dirty, which significantly reduces the efficiency of the heat transfer, so the quality cleaning is possible only with the removal of the front bumper and the dismantling of the heat sink.
