FWIW, I do too.<BR>
<BR>
Bob has been asking my advice for years on why his Pantera constantly overheated. I tried every suggestion I could think of but nothing seemed to work. Bob eventually shared with me that he had a radiator that would only flow air in one direction???? That sounded ridiculous, but he said his tests had proven it.<BR>
<BR>
What he didn't say, and I perhaps didn't think to ask, was HOW he came to that conclusion. If he just switched the polarity of the fans and spun them backwards, and compared the airflow, of course there would be substantially more airflow from back to front, if he had pusher fans installed on the wrong side of the radiator.<BR>
<BR>
The fact that the car ran perfectly while moving but overheated consistently while stationary points to an airflow issue. Installing the wrong fans (or rather, installing fans the wrong way) would explain that airflow issue.<BR>
<BR>
The other issues point to a deeper problem lurking in the car though. How does a cooling system get overpressurized? If a head gasket is leaking, and combusion pressures are allowed to enter the cooling system, that can certainly do it. One of my Sciroccos had a weepy head gasket, which would both allow a bit of fluid into the cylinder, and also allow combustion pressure into the cooling system. It was pretty easy to detect--besides all the 'mud' in my cooling system, I could demonstrate it experientially. I could approach the car when cold, remove and replace the radiator cap, start it up and run it for five seconds, shut it off, and remove the cap, and there would be a hiss of pressure being released. That pressure was being produced by combustion, not by expanded/heated coolant.<BR>
<BR>
So I'm calling BS too....I'm glad the car is finally fixed (or at least isn't overheating, although a compression check would probably be a good idea, as well as testing the coolant for indication of combusion gasses), but I don't think Fluidyne deserves to be bashed here.<BR>
