Please help me! Had problems with my Citroen today at about 25c early after the night shift. When I started my car everything was ok after a few kilometers controlled my car suddenly at 30kmh. In the cockpit came a lamp engine control and I noticed that the radiator fan ran on high but cooler indicator in the cockpit was as always.Then I put myself for 5min at the road edge and let it run in the stand gas. When I tried to drive it he ran again great only that the lamp in the cockpit did not run out.At home I noticed that in the cooling water tank everything was frozen and a noise in the stand gas came out of the engine room. Sounds like water pump! Has my car already pulled a harm out of it or or what else can happen? Please help! Mfg.tyler6
