96 Saturn SL-2 Radiator Fan Check

Well, let that be a lesson to me. I had installed one of the sparkplugs without its screw-on cap, and THAT was causing the radio noise and probably the PO341. The contact had to be arcing at the wire connection because of the gap. As for the radiator fan, that problem is with the temperature sensor, not the fan motor.

BTW, you have to look and look in Haynes to find the torque value for the sparkplugs --- 20 foot-pounds. I regapped the plugs to .040. They were all at .045.

Gosh, I love working on engines, especially Continentals and Lycomings. You can get to THEM without busting your knuckles. Just pull the cowl and GO! Riding lawnmowers are fun too.

As Bartles and Jaymes say, "Thanks for your support."

LOL.........I wonder who else caught on to that one?

I thought at first he flies, but what's an "AME"? An A&P? And then you don't take an aircraft up for a spin and cruise along happily. Do you? You get busy with the stick and the pedals and get it flying again.

Then he's got me flying east and I usually head westward.

Anyway, my little Saturn now purrs and doesn't make radio noise. And I can't get over that crankcase casting with the little aluminum balls that look as though they've been squeezed together.

As for the plugs on my puddlejumper, I can SEE them. *And* the neat little devices which safety the wires to the plugs -- 2 per cylinder for redundancy and to help get the flame across the wiiiiiiide combustion chamber before the exhaust valve pops open. Ancient technology compared to the Saturn's engine.

Which reminds me. There's a Saturn-powered airplane at Marion . . .

The little balls are from the casting process. What happens is they make a styrofoam mold of the block, then pack sand around it. Molten aluminum is then poured in which takes the place of the styrofoam - hence the little round balls that look like styrofoam. :)
