| Subject: | Re: Cooling impact of using firesleeve on oil lines |
Thank you very much for the feedback and picture. Giving the oil cooler its own
location makes a lot of sense but thats quite a major cowl mod. For those of
us in the U.K. it would mean going through a Mod application (which some have
done).
As a quicker attempt to fix this problem I managed to source and fit a 16 row oil
cooler to replace the 10 row one that is fitted as standard. Required a few
small mods to the brackets on the port radiator to which it is attached and it
only just fits under the top cowl and with its bottom edge just clear of the
exhaust stub by about 10mm.
However it has transformed the oil cooling such that we can now climb at max weight
direct to 5000 with no overheating issues/reaching the red line at all (although
in fairness it has also been slightly cooler weather). It seems to settle
at 120deg C max at full power in a 75kt climb. Once established in the cruise
oil temps are quickly dropping back to 90-100deg C. Also it hasnt affected
the CHT (I had thought we might be moving the problem there since now much more
of the port radiator is covered by the oil cooler).
So I have left the firesleeve on the oil hoses in place as we seem to have this
oil temp issue under control for now.
Many thanks for your input and good luck with your build.
Best regards
David

the spinner which gave it a little smile. The more recent change was to redo
the bottom cowl. Somewhat how Tim describes his. For hot Southern California
days, this help a lot in the climbing phase of flight.
