My guess is that you have a water pump seal weeping. Most of my 603s have
done this. On the first one, I did replace the WP and it stopped. On my

Yeah they do that too. As someone else already mentioned, the radiator
cap on the tank can look ok and cause problems. If the coolant only goes
down when you drive, look at the tank and cap. If it goes down while
setting, look at the WP, hoses etc

I Have two 190DT's, essentially the same engine. The white (Bent) one
blew the gasket at 120Kmi and I think the Blue one is going. Oil is
decorating the RF of the engine about where the chain tensioner is.
There is anecdotal evidence that they blow when some idiot (me) goes
over 161kph
yea, they do sometimes have head gasket problems but its usually oil
burning very badly, as in, blowing out the back. In that case, the
gasket blows out between #1 and the timing chain area. Never see one
burning coolant though.

Head cracks will lead to coolant loss, but also hard cold starts with
lots of white smoke and very rough running on startup. White smoke
smelling of glycol will persist until the engine warms up.
Coolant leaks from a bad head gasket are also known -- usually out
the exhaust side.

Check the evaporator drain for coolant, and pressure test the system
-- those plastic tanks have several failure modes that are not
obvious except that the cap won't seal. Test the cap, too.
Although it's cold outside, it's possible that you are getting
coolant burping into the expansion

Does the 124 have that little stubby hose between the thermostat housing and
the water pump housing like the 123 does? Thats what was leaking on my 240D...
I did the waterpump while I was there, I figured that was $45 of cheap
insurance.

From:
The mystery leak in my son's 603 300D turned out to be a crack in the
coolant tank just under a fitting on the side facing the front. Only saw it
when it got bad enough to see dripping under the car. Saw a small stream
squirting forward when up to temp and under pressure. Liquid steel cured it.
Yeah they do that too. As someone else already mentioned, the
radiator cap on the tank can look ok and cause problems. If the
coolant only goes down when you drive, look at the tank and cap. If

Wasser Pumpe or hoses in the area. It is a hillary with the york

remove the bracket to get to all the hoses. the pump itself you

Loren,
I am curious-does this explain the vacuum in the radiator or is that normal
on these?
If the water runs out, air has to get in or there will be suction. Maybe the
vent in the radiator cap is clogged?

Result of coolant expansion when hot (overflowing), but no vent action
in the cap, so lower pressure once it cools?

Look for a leaking hose somewhere -- coolant will go out when hot,
but when the engine stops, the pressure drop as it cools will pull
the hose down onto the nipple and seal it off.
And maker sure its vacuum! Squeeze the radiator hose when it's cold
