Hello John::
 
I would suspect #3!!  Airflow!  Baffling needs to be pretty rigid to force the air from the top of the engine (High Pressure) around the cylinders to the low pressure side of the engine.  The biggest culprit is the Heavy gasket that goes transversely across the top of the engine that separates the front of the cylinders from the accessory section.  This gasket must lean forward toward the propeller so that it acts like a ram air scoop when the top of the cowl is installed and forces the air down through the fins on the sides of the cylinders.  If this flap points to the rear the ram air will escape around it and will not properly cool the engine.
 
Hope this helps,
 
Wayne Woollard

Subject: [COUPERS-TECH] Ercoupe C-85 Overheating

----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----


I have a 415C with a C-85 that is running way to hot for this time of year.
 
Today , field elevation 450 MSL, OAT at 1400 MSL, 84 Degrees.  After 20 min flight time the Oil Temp was 213 degrees.  Steps taken to correct:
1. Verified the temp gauge and pickup are accurate.
2. Changed oil, cleaned screen.
3. Replaced all rubber baffling in the engine compartment.
   (needed it, old baffling was rigid and not flexible)
4. Richened up the mixture.
 
Anyone have any suggestions as to what else might be causing the problem?
