RE: [DML] Coolant leak under manifold ... but where?

["Video Bob" <videobob@xxxxxxxxxxx>]

I can vouch for this, I just had to replace ALL of the hoses and connectors 
that was part of my heater hoses system, it is easier to replace the whole 
nest of them in one piece that to try to
do them one by one.

Sometimes you can develop a tiny crack that has a pinhole, and under 
pressure the fluid can squirt
several feet away and pool up somewhere else.

I once had a bad oil leak in an old Pontiac GrandAM of mine, one side of the 
engine and tranny was covered in oil, sopping wet. I showed it to a mechanic 
who told me that it was the main seal
and that I would have to spend over $1000 to fix it.
So, I let it leak. I would just put a quart of oil in it everyday.
I never bothered to changed the oil filter or the oil because hell, it 
always had fresh oil in it! Right?
One day when the car was running, I dropped a tool and it of course ran all 
the way to the center
of under the car. While crawling under there to get it I noticed that there 
was a tiny little stream
of oil squirting from a pinhole on the side of the oil filter onto the top 
of the transmission.
HOLY CRAP! For the last few months I had been wasting money and oil on a car 
I thought was
doomed and all it needed was a friggin $3 oil filter!!!!!
I changed the filter and it never leaked a drop.

Something similar could be your problem, and you will want to change all of 
your hoses in one shot.
You can get a pre-assembled kit from John Hervey.
You first have to heat up your engine and poke your head in there and see if 
you can spot the leak.
Once you determine that it is your heater hoses, you need to change them.
...and if they have never been changed, then you need to anyway.

There is only one way to do it.
First off all you need a set of skinny hands.
I had to get my brother to help because my bear paws would'nt fit in there.
You have to remove your louvers and your deck lid.
Then I put a blanket over the engine and both sides of the pontoon,
then I cut a piece of plywood so that it fit directly over top the engine 
and pontoon.
This way you can climb up on top with your knees and reach down behind the 
engine.
The hardest part is getting a little stubby screwdriver down there and 
getting the hose clamp loose.
The other end runs down into the frame under a cover.

The only other way is to remove the who intake, and really that is not much 
better because
the hose connection to the engine is underneath the distributor and you 
can't take that off,
so you might as well do it the way I suggested.

Been there, done that.
