They make an installation tool that will snsure proper installation and no damage - not expensive and worth the $$ or you can rent one -

No need to use RTV around the seal for installastion

Thanks,Matt

You can use clean engine oil on the outside circumference only of the seal as stated in your factory service manual or take a chance doing it other ways.Its a big job if you have to replace that $10. seal again.Good luck with it

Hello, Just a quick update.... It's a big job. Haha. The Rack\Water pump\pulley all back on the car. I'll be honest, fighting with the lines back into the pump. They are in, just getting them down and tight - there's ZIPPO for room down there. Breaked for today before i "blew a gasket". I think i might go get some crows feet, that might help.
