    Anybody have a source for new water pump rebuild kit (impeller seals)? I know they are obsolete, but maybe someone has a fix for Sebring, 3500, Mistral???

    There is an easy modification which uses an industrial pump seal. The seal I use is a US Seal # PS360. Cost is about $30. It requires the impeller to be machined .130 inch. But most impellers need to be machined to repair the damage. I have used this seal for over twenty years in six different Maseratis and have not had one fail. If you must have the original seal contact me off line. I do have two.

    Thanks Gene,
    I should have contacted you first. We wanted to avoid any machining (and also had a fan clutch problem to deal with) so we sprung for the MIE conversion. $650 w/exchange for the whole pump with clutch. There is also a seal available in Italy that is recommended but again requires machining.
