I have a 351 windsor 1979 with a v-belt arrangement. The pulleys turn clockwise (as you face the engine) and the driver side inlet is below the impeller of the water pump.

With that info in mind, I seek your input on why my engine ran up to 200 degrees in ten minutes. The car was stationary with the fan running. It had coolant. No high revving.

It did not overheat. But the temp ran up quickly. My concern is that I am not getting proper flow and may need a reverse flow water pump for my application.

This was the first time the engine ran for any significant time.

Any thoughts?

Thanks, Greg

I'm afraid I can't help you with your solution, but I had to replace my reverse rotation wp for a standard rotation version since I am only running an alternator. Let me know if you need the brand new reverse rotation wp.

If it held at 200 deg. I would'nt worry. Are you sure all the air is out of the system? did you drill a 1/8" hole in the top of the thermostat? What water pump are you using? If you're not going with reverse flow (ccw) you should have a pump from an '84 Crown Vic (cw) or equivalent. Mike

You need to determine if your water pump is rotating clockwise, or counter clockwise. This is determined by the way you run the belts. You can post which direction the WP is rotating, or post a pic of your belt setup.

Another way to analyse this is to look at the water when the thermostat opens up. The water should flow away from the motor toward the radiator (upper radiator hose).

HTH,
Robert

Air in the system guaranteed. Burp it and go again. Just an FYI, reverse rotation has nothing to do with flow direction. It only has to do with the direction of the impellers as turned by the belt. HTH, Cheers Richard.

Pulling a vacuum will help with the air problem. Also - find out what water pump you have on the car. Is it a Std or reverse rotation pump? If the belt arrangement is turning the pump clockwise, then you need a Std rotation pump.

thanks guys for your input.

Richard my dad agrees with you. We will check the flow this weekend. Also, what do you guys mean by the 1/8 inch opening in the cap?

We need to run and burp to be sure.

Both come easily to this family.
