Bill3558 Posted May 13, 2023 Report Share Posted May 13, 2023 The rubber flap is falling apart. I guess it’s supposed to direct airflow to the oil cooler. But I don’t see it in the parts catalog. See attached pics. Any thoughts or suggestions? I’m tempted to just remove it. Quote Link to comment Share on other sites More sharing options...
Anticept Posted May 13, 2023 Report Share Posted May 13, 2023 Baffling. Not the confused kind, but the kind that forces airflow not to flow around the cooler and instead through it. You must have it. If it's in poor condition, replace it. When baffling is in poor condition, air goes around it and raises static pressure behind the cowl. This reduces airflow through all cooling components.

Bill3558 Posted May 13, 2023 Author Report Share Posted May 13, 2023 Thanks. I’ll call FD Monday and get one coming. Quote Link to comment Share on other sites More sharing options...
Tom Baker Posted May 13, 2023 Report Share Posted May 13, 2023 I have material to cut one if needed. It is a fiber reinforced neoprene rubber. The original was not fiber reinforced. I'm not sure if I have a pattern laying around anymore. It is just a rectangle with a few holes punched in it. This is what I use. https://www.aircraftspruce.com/catalog/appages/neoprenepyroglass.php Quote Link to comment Share on other sites More sharing options...
FlyingMonkey Posted May 15, 2023 Report Share Posted May 15, 2023 I replaced mine a few weeks ago with 1/8" x 4" baffle material, it takes about two feet and costs about $20. It's thicker and stiffer than the original thin black material. I just matched the holes to old baffle on a drill press (hand drill would work fine) and made it slightly wider than the radiator. Seems to work great. Link:Silicone Rubber Baffle Material at ACS You can use the same material on the muffler shroud inlet, if those pieces are missing you'll likely not get good cabin heat.
