I think I finally diagnosed my Honda Accord fan problems to a bad main ground. Many of the wires connecting the negative battery terminal to the frame were frayed and broken off. I believe that it is fixed because both fans now come on when I turn on the airconditioning and they did not prior to this fix. I then changed the coolant, bleed the system and filled the reservoir. As the manual states, I started the car and let it idle with the radiator cap off until it warmed up. The manual states to let the car warm up until the fan runs twice. Well.....my fan never came on. So I put the cap on and went for a drive. I drove for about 20 minutes and then brought the car back to my driveway where I let it idle for more time. Still....no fan. However, the car never overheated. The temperature gauge just stayed in the middle. I live in upstate NY and the temperature yesterday was in the upper 30's. Is it possible the engine coolant never reached the temperature required to start the fan because of the cool outside temperature? Also, what looked like a small amount of steam was coming from the reservoir. I don't think it was actually steam because the car had not warmed up when it started and the coolant in the radiator was actually still cold. I think it was just vapor from the temperature difference between the coolant and the air. Looking at the reservoir it appears that the vapor was coming from the reservoir cap. When I took the cap off and looked at it, it does not contain any seal....is this normal? Thanks, Bill
