Re: Stus-List Mystery Coolant

[Ryan Doyle via CnC-List]

Yes.  By "fresh water cooled" I mean my Atomic 4 has a closed loop cooling 
system with a heat exchanger circulating a mixture of water and antifreeze 
(just like a car).  It then goes through a heat exchanger that dissipates the 
engine heat into seawater that's pumped into the exchanger.  I primarily sail 
in salt water... Hence the "fresh water cooled" description.

You need antifreeze for winter storage in climates which freeze. Plumbing 
antifreeze is fine as it's biodegradable.

FWC does not usually mean *literally* fresh water cooled. North of Florida, 
most “FWC” engines use a mix of water and antifreeze. I buy the premix 50/50 
antifreeze myself for my A4.

Stus-List Mystery Coolant

For several winters, I was loosing approx. a cup of engine 
antifreeze..only in the winter, not during the sailing season.


I placed white paper towel in plastic trays under the enginefound 
the location of the leakturned out to be at a loose hose 
connection.tighten the SS clamps and problem solved.


Must have been the cold temp causing expansion inside the hose.

Re: Stus-List Mystery Coolant

[Headgorilla via CnC-List]

Good Morning Men,
 
In the early 80's I was crew on a large commercial fishing boat with twin 3408 
CATS. We had a coolant leak we could not find for love nor money.
 
This old CAT mechanic came to the boat finally and showed us the trick to 
visually finding coolant leaks.
 
He made us turn off all the lights in the engine room so it was pitch black, 
then he went down there with just a Maglite and searched over the engines and 
in few minutes was able to find the small bead of antifreeze coming from a 
pinhole in an elbow on the cooling system..

He said that when looking for leaks it is best to do it in complete darkness, 
this way your eyesight is not distracted by all the shadows and colors in a 
lighted engine room or compartment.

I would imagine if you were to pressurize the system (at night) and then look 
with a flashlight, you would find your leak pretty quick...

should be a heat exchanger on the engine . There is a sump under your mast step 
on the 30 - 1 also . The antifreeze may be coming from there from a previous

Hey everyone, 


Thank you for the responses last week about my tiller - which I went out to

Sometimes after heavy precipitation I find engine coolant in my bilge.  This 
ONLY happens after heavy precip - like last week here in NYC. 


I inspected the cooling system plumbing connections and hoses on my A4 and I've 
looked over the engine itself, there are no leaks I can see.  Also, the level 
of coolant in the engine's reservoir has remained constant for months.  

If it was leaking from the motor, the level in the reservoir would be going 
down, right?  That said, the engine is winterized, so the water pump hasn't 
spun since October.

The fact that it only happens after it rains is really confounding me too.  A 
constant leak from the engine would steadily fill my bilge no matter what the 
weather was, right?  The water system on the boat is winterized with pink 
antifreeze, so it's not that.


Any thoughts?  Thanks in advance.

  A constant leak from the engine would steadily fill my bilge no matter

Stus-List Mystery Coolant

[ssjohnson via CnC-List]

I have a similar problem.every year / winter I loose engine coolant into 
the 'after bilge'.   All hoses replaced.  Still happens.  Haven't found the 
source of the leak yet.Any recommendations for coolant dyes?  Probably less 
than a quart, but never a drop during the sailing season. Spencer Johnson1984

Hah!  Thanks for the reply.  But I have the original gas motor, so no
diesel on board.  It's definitely engine coolant - has the unmistakable
smell.

Thanks John.  I had no idea that was a fairly common practice.  That must be 
what's happening.  There's a section of the bilge forward of the motor and aft 
of the opening in the cockpit sole that I just can't see into.

Joe and Joel - thank you guys.  Apologies, I was on "digest mode", so I didn't

"nothing else on the boat looks like it".  Joel, I have a feeling you're right

either it was spilled or the previous owner intentionally put it down there,

I inspected the cooling system plumbing connections and hoses on my A4 and I've

Re: Stus-List Mystery Coolant

Perhaps coolant was spilled elsewhere and gets washed down by rain?  Not to 
sound too trivial but maybe check where spare coolant is stored on boat and see 
if it has been leaking from the bottle …

Hey everyone,

Thank you for the responses last week about my tiller - which I went out to
observe/fix today and then got distracted by another issue - c'est la vie.

Sometimes after heavy precipitation I find engine coolant in my bilge.
This ONLY happens after heavy precip - like last week here in NYC.

I inspected the cooling system plumbing connections and hoses on my A4 and
I've looked over the engine itself, there are no leaks I can see.  Also,
the level of coolant in the engine's reservoir has remained constant for
months.

If it was leaking from the motor, the level in the reservoir would be going
down, right?  That said, the engine is winterized, so the water pump hasn't
spun since October.

The fact that it only happens after it rains is really confounding me too.
A constant leak from the engine would steadily fill my bilge no matter what
the weather was, right?  The water system on the boat is winterized with
pink antifreeze, so it's not that.

Any thoughts?  Thanks in advance.
