WITH ONLY 14,000 MILES ON VEHICLE THE ALUMINUM RADIATOR BEGAN LEAKING WHERE THE CORE IS ATTACHED TO THE TANK. MANUFACTURE HAS SINCE REPLACED ALUMINUM WITH STEEL RADIATORS BUT WOULD NOT AGREE TO PAY FOR ANY OF THE REPLACEMENT SINCE THE WARRANTY TIME HAS EXPIRED.

RADIATORS SHOULD LAST LONGER THAN 14,000 MILES. *TR
