Coolant Leak at Front Corner of 1993 WL on Passenger Side....Please HELP!

[Jack and Liz Pearce]

Howdy, WL_Forum family.
We need HELP. We were using our hydronic heating system this past week.
However, we have discovered a coolant leak.
There is a coolant leak(drip) at the front corner of our 1993 WL, on the
passenger side. I am uploading photos of the area of this leak.(Pearce
1993 Coolant Leak) The coolant is dripping onto the grill-type metal
that is next to the HELLA cover.

Jackis trying to find the source of this leak. He has removed the front
nose cover(under the windshield wipers) to expose the heater core of the
OH dash heater . The front of the core is DRY. And the area between the
nose cover and the core is bone dry. Jack can see the coolant dripping
on one of the headlights, as he is lying on his back under the front of
the coach.What is the procedure for removing the headlight assembly? He
is trying to dismantle the right front corner section of the coach. Lots
of struggling and cursing going on outside. That is why I am INSIDE!! It
has been suggested to us that Jack check a petcock that is supposed to
be on the top of the core.

Any suggestions, ideas or recommendations as to how to FIND this leak,
petcock and/or drain hoses would REALLY be appreciated. It is cold
down here is SE Florida and we would like to use our hydronic heating
system. BUT we can't until we stop that leak.

Thanks,
Jack Pearce

Liz:

The front heater core is not part of the hydronic system. It
should be on a separate loop.

UPDATE ON COOLANT LEAK!!

Jack discovered an open petcock on the heater core and closed that
thing. Problem solved. However, this petcock is NOT the easiest thing
to find. I am uploading photos to that effect. I am going to name the
Album as Hidden Petcock.

Thanks to Ron M. for his reply. Appreciate it.

Ron, would the hydronic system circulate the Detroit coolant thus run
the chassis heat also? My Wabasto system will heat up the detroit

I believe that petcock is the bleeder for getting air out of the
chassis heating system. Such a petcock is also found in the front of
the 89SP. The SP has another one, either behind the left rear engine
access door or on the left side behind the rear engine cover, cannot
remember which.
