I always try the cheap and simple fixes first. I got a hot running Mopar to cool down by switching to a smaller water pump pulley, as per Don Dulmage. Worked like a charm, and got the pulley for free. Amazingly, I have also cooled hot-running Mopars over the years by installing a 16 lb radiator cap, and nothing more. This only worked on two or three cars, but when it worked it completely solved the problem. Cost about six bucks each time. I think fan shrouds are effective. What car manufacturer didn't use them? I have found they help the most when I also seal the radiator to the support and the hood, as Chrysler often did with A/C cars. You want as much incoming air as possible forced through the radiator, as you all know. ---- Please address private mail -- mail of interest to only one person -- directly to that person.
