[Vwdiesel] Leaky Plastic Water Outlet at Head on 91 Ecodiesel.

[Will Taygan]

I've been fighting coolant leaks for the past couple months.  Finally
tracked it down to the coolant outlets on the front of the head on BOTH
Jettas.  The 94 1.6TD conversion has the metal outlet, it turned out to
be a bad fit on the bypass hose (pulled the hose, put it back on, all
good.)

The 91 1.6 Ecodiesel has the plastic outlet and the new, bigger sensors.
I replaced the o-ring and what was a little leak is now a big leak.

I've got a new plastic fitting to put on, but before I do I thought I'd
check to see if there's anything I'm missing, especially since the first
attempt didn't go so well.

I'm planning on pulling the fitting, scraping the head a little, putting
the new one + o-ring on and tightening it back up.  Do I need sealant on
the bolt threads? Anthing on the o-ring??? Bentley doesn't say anything
but torque to 10nm.

Thanks,

Will.
