Looking for a wee bit of help here.
I drive a 94 16.i Astra Cesaro.
I just drove to work (nightshift) and my cars tepm sat at zero for 90% of the journey (45 miles).
On the last 10 minutes the temp gague raced up to 100 degrees, but the blowers were cold.
I thought , "cool, no water".
But no, When i got to work i slowly took the cap off only to be met with lots of hot foam (like soapy bubbles, but not).
Anyone got any ideas of what this could be, and is it likely to cost lots of money to sort out?
