Subject: Oil cooler size 360 angle valve
References: <list-3828586@logan.com>

Hello,
I've installed an Lycoming IO-390 which is very similar to the IO360 =20
angle valve.
My only problem is the high oiltemp.
In cruise I have 195=B0 to 210=B0   In climb after takeoff and landing I =
=20
get 210=B0 to 225=B0
Cyl head temp is between 350=B0 to 380=B0 never got higher than 400=B0
I use an Aero Classic cooler with 9 plates (8.14"x5.33"x3.62") in =20
front of cyl 3
I've installed also a spoiler to force the air thru the cooler. =20
Without this spoiler I've got 10=B0 higher.
I used all the tips I could get from Chris Zavatson, which lowerd my =20
temp already.
The next step will be a bigger cooler!

So I'm interested what size of cooler are you using.
Do positech coolers have a better performance as aero classic cooler?
Will constant higher oiltemp (210=B0) harm the engine.


regards,
Christian
