Yea, and be sure to inspect the replacement one too. I have seen
rebuilt pumps with very suspect impellers being recycled. A new pump
would be best.

From memory, a 3mm restrictor was added in the degas line. A new,
shrouded impeller design was introduced to correct a flow balance
problem caused by casting variations in the front cover. Earlier
models had a bypass loop in addition to the heater core loop. That was
eliminated. Not sure if the TSB involved adding one-I'd have to look
that up....
