I was encouraged to take care of everything while replacing the timing belts on our newer Subaru, the '89.

The metal tube inserted nto the water pump has an O-Ring on it.  The condition deems replacement is neccessary.  The groove that it resides in is square in nature and the O-Ring is now sporting a rectancular cross-section.

~Is the O-Ring in question just a 25 year old bit of rubber which is now misshapen OR was this O-Ring  originally shaped in a NOT-ROUND  manner?

Thank you, Gentlemen!

I just did the water pump on mine for the first time. The new one I got was round, not rectangular or flat.

My o-ring developed a leak back in 2001.   I coated it with some black rtv for a quick fix.   Now, 13 years later, Tom reminds me that I need to order one.  806927010.... 806927010... call dealer now... 806927010
