  Iain:

  No contribution on the fuel pump relay other than to say if the circuit is not designed to cycle on/off then toggling it on should be just fine.  However, I have no experience or information to support this theory.

  As for the viscous clutch.  The more obvious question is have you tested the fan clutch to see if it's at the end of it's life and in need of replacement?  I am now in the habit of replacing the fan clutch with radiator, hoses and tstat at or about 120k miles or so.  How many miles on your fan clutch?

  If you find it needs replacement, buy only the Behr brand.  The other aftermarket unit costs 1/2 the price but on two that I've tried they have been junk right out of the box.

  Regards,

  Dick

    Does anyone know if I will create any problems by jumping my fuel pump relay with a switch while I'm waiting for a new relay? Also notice that the new relays are 10 pin, as mine is 9 pin and one alignment (dummy) pin. Pins match up is the same. Repaired this relay 3 years ago and no problems since. Cannot find a obvious defect yet.

        Also, does anyone know what the plate on the front of the viscous fan does. Mine came off, broke the plastic cage and sliced 2 fins out of my rad. It didn't stay lodged in the rad so "do I need a new plate?"
