Just pulled my waterpump. There was at least 1/4 inch space between divider palte and impeller, maybe a bit more. I am adressing this in the next few hours.
Also, I measured my flex fan. It is 18". I have a 19" fan waiting for me, along with new waterpump gasket, at the parts store.
Tom, I also checked my radiator temp a week ago. It was 20 degrees lower than the gauge temp. I think this is normal.
I'll advise results...hopefully by tomorrow, if interested.
