Re: 99 Taurus Overheating
Rod,
Sorry, forgot to mention but I had also replaced the bottle and cap with original ford parts. Yes, I'm sure the thermo is in correctly but didn't notice the jiggle valve? Impeller is moving in correct direction per belt routing as well. As you might notice, I'm running out of things to check. Like I said, you can be doing 60 mph but if you punch it into passing gear, it will start to overheat. Keep it at 60 and it's fine. I have also read that somewhere around 62-65mph the PCM will shut off the cooling fans but the fans shouldn't be needed at those speeds anyway. Any other ideas?
