[C36IA] engine temp #2

[Paul Jay Walchenbach]

the leaking 'water' was in the pan/tray below the oil pan and engine  
and not in the oil (no evidence of water in the oil, no froth).

green coolant overflow level normal in cockpit locker.  thru hull  
open, strainer clean, water splashing out exhaust.

i am thinking thermostat or heat exchanger.  question is, how to i  
trouble shoot to isolate the problem?

and

if it is the heat exchanger, how do i 'clean' or if needed, replace?

By in the engine sump do you mean the oil pan?  So the Oil is medium  
brown and probably a little frothy?  If so you have water in the oil.   
Unless someone accidentally added water to the engine you have a leak  
from the coolant to the oil.  This is not good!  More than likely this  
is from a bad head gasket.  You definitely do not want to run the  
engine this way.

Have you checked the coolant level?  I'd guess it's low and that's why  
you overheated.

Is your oil level high?  Again, I'd guess it is but the coolant may  
also have boiled out.

i too have an engine temp issue.  last night after only 5 minutes of  
motoring my overheat alarm came on.  the temp gauge pegged at 220. we  
shut the engine down and took off the engine cover.  there we found  
medium brown liquid (color of dark beer and the consistence of water)  
in the engine sump and a very hot engine.  couldn't tell where the  
'water' was coming from.

after a few minutes i restarted the engine and found that warm, not  
hot, water was coming out the exhaust at about the normal rate.  i put  
my hand on the heat exchanger and it felt 'cool', maybe 'warm', but  
not 'hot'.

question:  what is the trouble shooting sequence for these symptoms?

thank you all!
