And when you cannot find the 0552106-3 winterization plate there is always DUCT Tape :wink: ...Brad

I use duct tape, and I remove it and clean up the adhesive right away when the airplane goes back in the hangar. No damage to paint yet (Imron). One of these days, I'm going to make a set of proper baffle plates after the Cessna design.

John,
My kinda tongue-in-cheek comment is because someone in the past had the proper winterization kit, but it fit so loosely that we had to keep it in place with Duct tape :roll: Just seemed funny to me using a very useful tool to hold a proper thing in place.....Seems redundant.....Brad

I bought the winter front from Spruce about 4 years ago. Its spendy for what you get but is the exact cessna part number fot the 170B. I'm always trying to cram 30hr days into 24 so it was easier to buy than build.

I don't know if my planes temp gauge is accurate or not. Measuring the oil or engine temp after landing and shutting down may or may not show what the temp is while flying at 100mph. Therefore, to check the engine and oil temp while in actual flying conditions, one should stand on the wing strut with a heat gun or turkey fryer temp probe.

When flying in the winter, I used to feel good when I shut the plane down and saw moisture dripping from the breather tube because then I knew the oil temp was hot enough to boil the water out. But that also means there is still moisture in there. Now when I shut the engine down, I like to see a drop or two, but know that the flight was long enough to get all the moisture out. I just assume that the oil temp gauge is wrong but want to see it rise to about the same spot every flight.

2cents worth

FWIW, be careful using duct tape as an air flow reducer. I owned a C-140 years ago and tried the tape method and apparently blocked too much air as I had to make a quick return to the takeoff airport with a cockpit that was starting to fill with smoke! I just put up with cold feet after that!

When I do this, I block the same area of the cowl opening that is covered by the Cessna winter baffles. I haven't had a problem yet.

And be sure to leave the area just in front of the cabin heat scoop and carb heat scoop unobstructed.

N9149A,
Keep in mind that the oil temperature bulb is immersed in the oil which is passing around it at a rather rapid rate, therefore the temperature of the surrounding engine structure is able to absorb heat from the oil touching it thus cooling the oil.

I have been using duck tape when necessary, without any problems. I too would like to manufacture the plates rather than continue to use the tape. I have seen the parts manual depictions of the Winteration kits, however I have not seen anything that contains measurements - is there a diagram avaialble with measurements?

Can you post a picure of that on a plane, and show how it's latched on. What gauge of material?

I don't know what gauge and I'm not at home. I'm sure you can get something close enough from the following pictures:

Have you reinforced the two forward horizontal "bars" of the upper nose bowl? They often crack on their own yet yours look very sound.

I believe the left side is still stock with no repairs. The right side has cracked and been repaired a few times prior to my purchase 4 years ago. I do not know if a winter kit was ever on my plane before I bought it as I purchased the winter kit after I purchased the plane.

I was wondering if anybody had a winter kit for a 48 or pictures for one. As for temps here in Indiana I think we are now stuck in the teens and I need to do something other than duct tape.
