[Vwdiesel] Coolant leak

[Bryan Belman]

Oh, just re-read this.  I am guessing this is a 1.6TD motor, not TDI
no EGR cooler.
look for the weep around coolant flange connections to the block, they tend to get pitted on the block and may need more then a new O ring to seal.
but you only have 1 on the front  of the block, facing the Inj. pump and one on the end of the head going to the heater core.
I had a weep on the 1.6TD I ran for years that turned out to be the lower hose, water pump to oil cooler, but it eluded me for 2 years before I pin pointed it.
It rarely leaked on ground, but must have dripped when motor was running with some coolant pressure in the hoses.

  Head gaskets can leak externally but it's pretty rare.  It's usually between cylinders and into close neighboring water jacket passage holes or else the oil passage near cylinder number 3.  That one is more prone to external leakage than any of the water.  
  Look closely then look closely again.  Most likely causes would be a slight weep around a hose connection or else one of the head flanges, moreso if you have the plastic flanges.  The water could easly be a very slow leak, bulds up on a ledge, from movement, then drip on the floor with little evidence where it originated from.  Gotta look really closely for any crusting, color from your antifreeze or a cleaner trail.

I have a coolant leak that seems intermittent but will lower the 
eservoir level over a few days and leave a few spots on the garage 
loor. I have checked all the hoses and the water pump and cannot find 
ny traces of antifreeze on them.I thought I had found the leak when I 
ound coolant on the heater control valve. I changed the valve and the 
eak seemed to be cured but reappeared after a few days.  Is this type 
f leak indicative of a head gasket issue? I would expect to see black 
pots in the reservoir if my head gasket as leaking. Can I have a head 
asket leak to the outside that doesn't show up in the coolant 
eservoir? If the head gasket can leak like this, are there any 
referred locations where the leak is most likely to occur? The motor is 
turbo motor with turbocharger installed in a 81 Caddy.
