And this is with a 195* Stant thermostat.

Actually, I don't see any improvement in engine temps with this new pump. And I didn't need any improvement, only changed pump because of a slight weep hole leak. And only bought Edelbrock because of "quality" concerns.

But like I said earlier, car does not over heat to the point of being harmful. Just spikes up and down and runs warmer than before, both in town and open road at constant cruise.

Outside air was 65* Car warmed up nicely to about 86 and held that + or - a degree or two until I got off the interstate. in moderate traffic it held 200 to 205 steady. Very normal but may be a couple degrees higher than the stock tstat. I'm not sure as I didn't pay that much atten to the temp and I don't drive it much anyway. As I said above I did not do anything special to "burp" it. Hope this helps you.

So, if you get the standard pump, it might fit but the vanes might be in the wrong direction. Just wanting to make sure. Also, do you happen to have a scanner to see what temp the ECM sees while it spikes? I don't really trust the gauge.

And yes these cars do have the reverse rotation pump.

Thanks

Shopped on Summit 3 diff pumps edelbrock-8815 $242.92 ; FlowKooler 1688 $116.97 ; Summit sum-312635 $62.97 the last three are all high flow reverse- I guess that's what I want, the base Napa is multi directional, haven't pulled the original Delco to see the impeller direction.

Any follow up to this thread, or any additional pump advice. I leaning toward the summit based on price.
