Hi Please bear with me as i know nothing about engines
I was driving down the road and someone pulled out on me so had to slam on the breaks for a splt second i didnt come to a stop but herd a strange pop noise,
Steam was escaping from the bonnet area (but only for about 5 seconds) where the water goes and the temp guage was in the red i continued driving cos i couldnt find a safe place to stop!
As i continued to drive the temp guage went slowly down and still in the 90 - 100*c mark but not in red
A friend suggested that it could be an airlock but i cant see where the steam escaped from as all pipes are intact and look ok
Also during this time the fan never came on

I have only had the car a week since my last cars head gasket blew up
Thanks
Beau
