[Vwdiesel] New head installed 91 ECO

[Val Christian]

The timing won't make a big temp difference on that engine.

Chances are you have some air in the cooling system.  

On a side note, there are some vacuum devices which "burp" air out of 
cooling systems, which make them easier to fill.  Anyone have one?

Can I just take an old pressure cap and hook it up to a vacuum pump?

Nick, check your cooling system for air captive in the head.  A few 
thermal cycles will help, but it would be better to somehow get it out
first.  Chrysler puts a plug in their 4 cyl heads for this.
