Dude, Acura needs to start using all-aluminum radiators. This crap seems to happen alot.

I don't know about the other guys but for some odd reason it was a total pain in the ass trying to disconnect the radiator fans on my '97 GS. I could disconnect the main connectors but both ends of the connectors (this happened on both the left and right fans) were like GLUED onto the fan, meaning disconnecting would just free up a little slack and totally freeing the fans were out of the question. I ended up just taking the fans off while the radiator was still in the car and flipping them out and resting them over the engine then I yanked the radiator out. Still worked though.

Oh and about the Honda/Acura Antifreeze, make sure you only use the genuine stuff. I screwed up and used Pestone in the yellow bottle. A week later I ran across a thread about silicates being a no-no in Japanese cars. I emailed Prestone and they told me to flush my cooling system thoroughly then only use Honda OEM antifreeze. If you go to a Honda dealership you can get the full concentrate which is a better buy than the premixed stuff. I thinking 1 gal of premix is like $16.25 or so and 1 Gal of the concentrate is like $18.25.
