I have been following this discussion because I have the same problem with my car. Temperature is fine at speed but rises in traffic. I am in the process of adding AC, so I am concerned what is going to happen. I already have a Flowkooler water pump and a Be Cool radiator.
My car currently has a 2 electric puller fans and 6 1/2" pulleys on both crank and water pump.
My question is: where can I purchase either a 5 3/4" water pump pulley and a 7 1/4" crank pulley? I may need to consider going this route in the future.
