The Fan Fix @ SpecialTAuto, and Fanzilla from Zilla Products are both 
devices that are designed to help the electircal portion/function of the cooling 
fans. Niether are failsafe items to prevent overheating, nor will they increase a 
cooling capacity. Only a properly bled system, and/or a larger radiator will 
accomplish that.

The bleeder kit that DMC Joe sells is invaluable. Certain engines such as the 
DeLorean require you to purge the system of air bubbles which will cause 
"vapor lock". Quick answer: Assuming that your cooling system is functioning 
properly (which it sounds like it is), you've probably just got too much coolant 
inside. When things get hot, they will expand, and water is no exception. So 
the water probably just got a little hotter than normal (although still within a 
safe operating range). Since the water got hot, it expanded. The radiator cap 
functioned properly, and it let off the excess pressure so the cooling system 
wouldn't be damaged. And it did this until the water stopped expanding. I too 
have had this problem as well a couple of weeks ago. And just like you, it 
didn't happen untill I stopped the car. As long as the car stays within normal 
operating temps, everything should be fine. But in your case, it's hard to 
determine if you had the cooling system over filled, or if it was simply air 
bubbles. I would reccomend to first get rid of the blue relay, and replace it with 
a crimped connector, and install the Self-Bleeder kit by DMC Joe. These are 
both inexpensive repairs, and ones that are beyond important for your car.
