Oil cooler inlet plug

I wonder if anyone knows where to buy or how to fabricate a plug for the oil cooler inlet on my Arrow II? If I park for a few nights outside, it would be nice to know no critters can get in.

  • I made this out of scrap aluminum. Is this what you're looking for?

  • Or do you mean this in the bottom of the photo? This is like a small pillow. I got it from Bruce’s Custom covers.
  • I should have mentioned this is for the air filter and main engine inlets as you can see. I have also heard from others that use metal tape over the oil cooler inlet where Scott is showing. It would only be used for cold temperatures however.
  • What you're looking for is an air cooler winterization plate and your aircraft should have come with one. There is a part number in your manual and you can purchase one for about $50. However, you can also make one for basically free.

  • I'm looking for something to cover the inlet "scoop" on the lower right side of the cowl for oil cooling. I'm thinking it would be a good place for birds to come in if parked outside for a few days. Maybe this isn't a problem. It should be waterproof.

  • Scott,

    He may mean the oil cooler inlet duct which looks like an NACA inlet on the lower cowl, right hand side. My '69 Arrow has one also.

  • Oh! Got it, much thanks Jim. So how about shoving a piece of foam rubber in there. And put this on the foam rubber plug. https://www.sportys.com/pilotshop/remove-before-flight-streamer.html

  • Simple enough. That should work. I'll probably just tie it to the cowl plugs so they will all come off at the same time at preflight. Thanks

  • Glad to help! Sometimes it's the simplest of solutions, lol.
