Hello Together I have the following problem: Before 800km kilometers I have both head gaskets, water pump Thermostad stop everything that belongs to it let renew. In cold condition the marking on the balance tank is exactly to maximum. Then the car ran warm times in the stand gas. At 110 degrees (according to temperature indicator) I switched off the engine. Here I noticed the following things. Hose from the Thermostad to the cooler is cold. All hoses are relatively hard (also the hose that stays cold) as if there was pressure Ok sounds primarily to Thermostad but when I drive everything is normal. Cooler gets warm all hoses are warm and the fans set just before 100 degrees Does someone have an idea how to go on? Greetings and thank you in advance
