I got an estimate of 3 hours ($85 each = $255) for labor to replace the leaking waterpump. The shop said that elsewhere 4 hours are the standard.

1) Do you think I have a deal, provided the job will be well done.
2) At such labor cost it does not seem to make sense to replace only the O-ring. Cost saving for part is about $200 with the risk that it will be leaking at the pulley some other time.

Thanks for your input.
