Away!
No worries then about it failing where it is now....
Good point. Feeling better now.
Seriously, though, I've done a little reading...
The OE pumps are made in Canada or Mexico. (should say on the pump, I haven't looked at the one I have yet). The PRO are made in China. The OE have ball/roller bearings. The PRO have sealed bearings. Both have heat treated impeller shafts and coated seals, but the OE has a stainless spring.
I have also seen for the first time that the outlet and thermostat are different sizes. The OE on rock auto came with a thermostat and housing. I'm assuming this is because it's different than what's in there now, which is weird seeing that it's the "OE" part. "Revision", "updated", I have no idea. Will read more.
