[C36IA] engine temp #2

[tjsoko at aol.com]

Steve,
Because of the way it is constructed (in one end, out the other), and because brass/bronze conducts heat so well, the whole thing would probably be hot.? 


Paul,
I know this is a really stupid question, but I have to ask it, because it happened to me.? Is the "fan belt" in one piece and operating properly?? If not, your circulating pump won't be?circulating any water, and the engine would overheat right away, yet water would still be coming out the exhaust.

Paul, 
I have had recent experience with removing and replacing the heat exchanger.
But first, if you suspect this may be the issue, it's very easy to remove the round end plates off both ends to check inside.
When replacing, each has two gaskets, one large one the size of the round end cap, the other a small o-ring to seal the bolt- this ring goes on the inside of the plate I think, check while removing yours.

If you have to remove it, it's not hard, less than an hour to undo the hoses and remove the clamps that hold it. 
Refer to Fred J's email about two weeks ago how he held the two-stiff- holding straps to get the bold started.? I did the exact same thing a year ago!
Good recommendation.

But one thing, if the H/E (heat exchanger is the problem, wouldn't one end by hot to the touch?? Tom S?

Attached is a photo of what one should look like looking down the axis (more or less) of a clean H/E.
AND.... a little photo-write up I did about the pencil zinc which shows crud before having it cleaned

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??
