[Vwdiesel] Ways of cooling an AAZ

[LBaird119 at aol.com]

  As stated, first check for a solid stream of coolant in the small line to 
the 
reservoir.  Bubbles, spurts, steam are all bad signs of a blown head 
gasket.
  If no bubbles then you want a good, solid stream of coolant coming back.  

If not, then you're looking at a circulation or flow rate issue, like 
clogged 
passages or a bad water pump, collapsing hose, etc.

  Gotta analyze the system and see where the problem/s can be.  First is 
heat.
Excess heat?  Bad injector, plugged intake, exhaust, intercooler not 
getting 
  cooling air, leaking head gasket.
Transfer of heat?  Low coolant, poor circulation, restrictions, straight 
water, 
  thermostat, plugged heater or radiator.
Elimination of heat?  Bad cooling fan, thermoswitch, fuse, etc.  Plugged 
radiator 
fins.

  Check temp in the reservoir with a thermometer, check the radiator hoses 
and 
radiator once it's at full temp, check for proper circulation etc.  Follow 
the heat.
