Faults:

My old Legacy overheated last year. Problem was partially blockage in heater core. Recommended repair is 9mm t shunt across the heater core. No further problems.

The problem is peculiar to Subaru.

Outback 2001:

No problems yet, but are watching for signs of over heating as the dealer says this problem was not cured until 2002.

General Comments:

Both cars are very reliable.
