Changed over the thermosat today and that bottom 10mm is a ****** to get to with my rather big hands.
Anyway thats it done and flushed the full system out and all topped up with new antifreeze for no doubt another horendous winter.
Temp sits bang on the 90 now rather than the 70 that it was.
While i was under the bonnet i swapped the two middle injectors about as iv got a PO171 trouble code witch if i remember correctly says summit about over/under fueling on cylinder 2.
Can anyone confirm what way they are numbered as in 1 at timing belt or opposite end?
Car seemed great on way home and pulled better than has for a long while and so far no engine light on, so hopefully iv fixed that too but im not holding out much hope.


1x S3 and 3x Fiestas.
Yeh 1 is timing belt and 4 is clutch end.
