I have a 64 pontiac 389. I have a overheating problem. Tha car when driving its it does not over heat, yet when stoppd or in stop in go traffic (normal in miami) it starts to climb. I put a oil cooler and i have a 16 electric fan in the front to push my car does not have a fan cover (other name but don't know how to spell it) I used to have a straight flexfan but removed it to install fan clutch with big fan blades off a chevy caprice . It goes down when i am driving but goes back up when stop. I am wondering if the 64 came with a fan cover. I have not seen fan cover for sale on any pontiac auto part. I put the timming back some, it just take longer to warm up. I have heard off lean and rich what does does saying mean and if it would help. I have a 160 new thermostat. Thanks MIGUEL
