• My 1.6td is running Evans NGP+ coolant (low psi ) with a 19*22 *3 Griffin double pass NASCAR radiator and 16" Spal fan.  I'm thinking that I must be leaking compression into the coolant system.  The head is newly rebuilt though.  Any suggestion would be great.

• Yup, head gasket, cracked head, or cracked block.

• Agree with above. My Evans wasn't pressurized when I lost my WP pulley and the temp was WAY past 250. It only expanded a little and dribbled out the overflow hose(open system)

  The coolant system should only pressurize once it gets hot enough for the coolant to expand a bit. Then at higher temperature it should pressure to keep from boiling over.
  
  PS: Tie her up and put her in the basement. (I didn't understand the question anyway)

• Well it looks as though I gonna have to pull the head again.  What is the likelyhood that a 1.9 head will mate up without issue?  Btw it looks like I may be in the market for a head, if anyone has a GOOD leed please let me know.  Thanks for all of the prompt input.
