My "scirocco" is missing...



Just something to think about - not to worry any one :)

Tstat is definitely a contributor to low engine temp, but if your water 
temp is in the normal range, you should get heat.  Tstat is already open 
when you are at the normal operating temp for the engine.

So I am assuming the issue with no heat is that the engine temp is low 
also, so the water temp is too low to actually heat the air in the heater 
box.

Now comes the thing to think about:

IF your water temp is at normal and you still do not get any heat in the 
car then there are a couple of issues I have experiences in the multitude 
of used a1/a2 cars my family goes through :)

Original heater cores that have clogged.  You'd be surprised at how often 
someone "fixes" a hose leak with some rad sealant. I have taken out heater 
cores that barely have any flow at all.

I have found also found, that an engine that runs normal op. temperature 
with a good heater core and still consistently does not produce heat 
usually is the first sign of a weak head gasket.

If there is a very small leak in the head gasket the small amount of 
pressure keeps the water from flowing through the heater core at a decent 
rate.

Usually you can confirm this with a plug that has been washed clean.

I'm with you guys on this. The rieger is overdue for the yearly coolant
flushorama, I'll throw in a virgin (undrilled) t-stat for the sake of
troubleshooting.
