Wait for it. Exactly three months later, the new matrix burst I was driving home on the M3 when the car
suddenly filled with steam and the floor was flooded with that evil-smelling coolant. The RAC came to
the rescue. He joined up the flow and return heater hoses so that I could get home. Thank goodness I
had a good overcoat and gloves.
This time the same end pipes on the matrix had failed, having been eaten away from the inside. I didn't
have the nerve to take this one back, but bought a new one and phoned Andy Burnett instead.
Andy thinks my problem was contaminated coolant, and I have followed his advice and flushed and
reverse-flushed the system out several times and then filled up with fresh anti-freeze. He explains how
coolant can become contaminated, but the high chemistry eluded me. I am praying Andy got it right I'll
be praying extra fervently in mid-June, when the new matrix will have been in service for those fateful
three months.
