#1: steam from radiator expansion bottle cap Author: mikesrob, Posted: Sun May 19, 2013 2:25 pm ---- Hi, as my daughter was parking her peugeot 206, 14 petrol to-day she noticed a lot of steam and water coming from the expansion bottle cap, when the car had cooled down,I re filled the bottle with water, I noticed that the rubber seal inside the cap was not seated evenly in the groove but half on one groove and the rest on a lower groove, the seal also looked stretched,would this seal in this condition cause the car to overheat like this and allow coolant to escape or is there another reason? thanks in advance for any replies,Mike.

If the seal / cap is not fitted properly I would assume you could lose coolant this way. I believe you can get a replacement from peugeot.
Is the car showing any other signs of overheating?

Now I remember how I knew this. You told someone else the same thing the other day

I would like to met the person that answers this! I have never taken the car for a run (to running temp) and then start touching parts under the bonnet to see if they are hot.
