After driving 50 mls. air gets trapped in my 328 radiator. When driving theres no temperature-problem. On idle: temp builds up to 105/110 degrees C. Coolant poors out under filler cap, so its not an faulty reading. I noticed that only one radiator fan is working so there is probably a electrical problem (bad fuse ore relais. OK. Whats bothering me is that I need to bleed my radiator every day after 100 mls. Air keeps on coming out. Anyone know where the air is coming from? Is it a failing headgasket ore is it possible for air to be sucked in the system by the waterpump ore else? Any suggestion would be great!
