Hello.  I was riding around in my van (90 GL) yesterday and all the sudden the cooling fan trips on while I am sat at a light.  This has happened before, but what was outside of normal was that the fan was making a huge amount of vibration that pretty much shook the whole van till it got the engine temp down and cut off.  I figure something is hitting the fan blade or maybe a mounting screw came loose.  My daily drive isnt very long and generally the cooling fan doesnt come on during the drive.  I am hoping someone can tell me the best way to get in there to look and see what is afoot.  I looked into the front end, but I can see the radiator is in the way.  What is the best way to get to this fan to investigate the problem?

Thanks,

Jeff
90 GL
