Hello, who can help me with my M25 multicar?! I have restored one and have registered it now also endlcih but I still have a problem there. the engine is getting too hot again and again. So that he pushes the water out of the pressure compensation tank out. I have already pierced the water channel 20 times but somehow it gets hot again and again. If I drive up to approx. 30km/h it keeps the temperature but as soon as I drive 40-50km/h it does not make the cool anymore!!!! So I please you to help all of me. Already in advance THANK YOU!!!! MfG Micha
