ive also used insulation tape around the bottle cap threads which seems too work well i also had this problem with luke warm heating i fully flushed the cooling system changed the stat bleed the system numerous times still cool in the end changed the matrix and it was like a new car heating really good never had a issue after.I guess some of the matrix tubes was partily blocked alowing only a little hot water too flow through the matrix.
