318Touring 40 Report post Posted May 25, 2007 (edited) The fan is for the a/c system only. Have you checked that water pump isn't leaking. Leaking valve cover gasket will be my first suspect. Edited May 25, 2007 by 318Touring Quote Share this post Link to post Share on other sites
jpp 0 Report post Posted May 25, 2007 Did you flush your coolant system out correctly? This can leave air in the pipe work and not cool properly. Also could be fan's bearing not effective, and water p[ump as mentioned. Quote Share this post Link to post Share on other sites
