just wondering i have an '09 ranger 4.0L i know were the alternator and fuse box are but were are these coil packs. what do they look like.

 

rectangular box, i think it is on the drivers side rear of the engine (top) has all the spark plug wires coming out of it... it replaces a distributor cap

 

i would cover the coil pack and fuse box

 

Ok so I'll cover those but what would be safe to clean the coil pack alternator and fuse box damp clothes or some friendly spray.

 

I wash it all, just don't "kill spray" stuff. Hold the wand about 2 feet from the engine and move around a lot.

 

when i do it, i stand in front of the grill, and just get everything soaking wet, but i don't really pressure wash it, i just super mist it...

 

I heard WD-40 stood for not only 'water-displacement' but also when they were coming up with the formula for the aerospace industry that it was the 40th try before they got the formula right. I believe I heard about that on the discovery channel.
