156 T-Spark Coolant system
A few month's ago I went over a pothole which caused my expansion tank to split. Got a second hand one, fitted it, ok.....I thought.
Now temp gauge shoots to max, heater stone cold........after a few days no water in expansion tank (although it only takes about a litre to bring it back upto the correct level).
Have I gotta leak I asked myself.......although I could never see any signs of a leak......so I added a sealant to the water system......still the same.
I was gonna replace the thermostat but after speaking to a few peolpe they are certain it's an airlock.
My question is..........how to bleed the system? I've found the rad bleed screw, where else should I be looking?
Thanks in advance
