If the electrical fan turns slowly, it can be that your pulse width modulated relay has a problem.
This car doesn't have a mechanical fan run off the water pump....just the electric fan.
Is the pulse width modulated relay the one that is well hidden in the passenger side fender? I've had to replace that one awhile ago (what a pain) as the fan didn't come on at all then. This time, the fan is coming on just not screaming fast. Now don't get me wrong....it isn't turning so slow that you can see the blades...but it isn't turning fast that it's making a roar either. And last night while testing it, the temp was around 230 and not blowing any harder than it was at 190ish.
