New K3 Set-up: Need some suggestions from you...

All,

I’m about to purchase a new (used) truck with a Nathan K3 set-up, and would really appreciate some suggestions from seasoned horn blasters.

Here is what I would like to know:

  • Is it better to purchase a kit or piece together a custom set-up? (Keep in mind, I am considering using a Graham White Valve instead of an electric solenoid- more on that in a minute)

  • What are people’s experiences with manual valves? (I’ve read mixed opinions, and I am aware that the airline must come into the cab/driver area)

  • Can you make any recommendations for me bearing in mind that my set-up will be exposed to the extreme weather of the high Sierras (deep snow, below zero temperatures, moisture)? > I think this is what killed the compressor on my SUV.

  • Any other pieces of advice? (Compressor? - Something fast, quiet and capable of performing in extreme weather conditions)


Here is some more info that might help you advise me:

  • I plan on installing the compressor OUTSIDE, under the chassis
  • I plan on fabricating a sound deadening box for the compressor to reduce vibrations and noise
  • As mentioned, the set-up could be exposed to extreme weather: deep snow, ice build-up, road moisture and heat in the summer)
  • As for “$” I’m willing to save-up and spend on a set-up that is going to last longer and work better, versus a quick set-up that will be prone to problems.

Thanks for your time and help. / Justin

  • I’m going with a Chevy Tahoe or Silverado. A train horn installation won’t be the ultimate deal breaker for which model I’m purchasing, but I’m keeping a future install in mind when I look at the dash/cab and under body.

  • I had a P3 set-up in my Acura, and it worked great for years, however I think the weather this winter (feet of snow in days, below zero temperatures, etc.) killed my compressor and wiring

Justin,

Since I’m in your neck of the country, here’s my install:

I haven’t had any weather related issues and we’re in the Boise area. Like I said in my install post, I’ve got some leaks but I’m hoping to fix those this summer with some upgrades … including an XD3000.

I’ll have to see if I can keep the frame mount for the new compressor, but I may end up just going for an in bed install and plan on buying a hard lockable cover for the bed.

doesnt matter if u piece it or buy together. just as long as ur happy with what u buy…

get atleast 10 gal tank. run dual 480 viar compressor. all half in lines. a water trap.
if u do manual valve its good but u cant hook it up to a remote if u wanted to do that route…
use loctite on fittings… and take pics of the install

If you go with an Oasis compressor, rinse the compressor with fresh water at the end of the day to remove any road salts that might used in winter and spray the motor brush area with WD40. It’s a good idea to occasionally spray WD40 there anyway.

If you want to keep it looking new, spray it with “Fluid Film” before mounting under a vehicle and spray it again about every 2 months. We haven’t tested that product but I have a customer in New Jersey that swears by it.

It’s recommended to mount the air intake filter in a dry location for all compressors.

Installation is done! I will post pics soon.

sweet cant wait

Looking forward to it.

Sweet post away. Ready to finish my k3ha set up.
