Hi, the water pipes feel very firm as if they are holding a lot of pressure. This is the case even if the car is only driven for 5 minutes. Water temp stays very low someone mentioned that this might be due to an open thermostat. Oil temp is fine also. So could this be a sign of something sinister or am I just being paranoid? I also changed the coolant and flushed the rad until water was clear and nothing has changed it was doing this before and after the coolant change.
