I picked up a new small block CSR water pump, new still in box, but I bought it from a friend, who bought it from a friend, so no warranty , and installed it and went through quite a bit of trouble relocating alternator, and after all this work it wont pump, motor runs, won't pump. Rechecked wiring, even hooked it up backwards, won't pump either way. Really sucks ?

I had to pressurize my Meziere with a little air in the radiator to get it to start flowing. Then I had to get all the air out of the system,

Try putting the cap on the radiator and then squeezing the radiator hoses to get the air pocket moving. If that doesn't work your going to have to loosen the allen head bolts closest to the pump motor with the pump running. Your trying to get air out. Sometimes I have to even take a bolt out of either side and roll the pump a little to get the air out.

The other problem with this,I am using a motor plate, While it may not matter, it is another 1/4" or so,But I used the stock water pump this way and had no problem, in fact wish I had never seen this new one,lol Stock one worked fine,but the motor went bad, new Moroso kit was $79.00, this was $100.00. Actually a 69 Mustang Blower motor looks the same as Moroso water pump motor and NAPA has for $23.00.

Want to thank everyone, Burped the air and it works just fine!Only thing I noticed is I used to start it let it build to about 130 degrees and turn on the water pump and temp gauge would drop back down to nothing and gradually build back up,and go all the way up to about 190, this one didn't do that,just stayed at 130 and then built up to 150-160 and ran it quite a while. Would have had to shut it off with old pump. Thanks again, I was pretty disgusted, Just spent a month,pulling trans about 5 times to fix a leak which turned out to be converter snout (which was fairly new)and I kept going through the pump,and I pulled the engine for a hairline crack in the Milodon oil pan and replaced. Just a long 5 weeks or so....
I have the same problem every year after I drain the anti freeze... it gets a air pocket, I'll fill it then warm the engine up(pump turned off) and when it gets warm I shut down the engine then turn the pump on and off a few times then it'll finally pump, then I can top off the cooling and all is well. I also put a clear plastic tube in the upper radiator hose just to make sure its pumping. I only have the problem if the cooling system has been drained

Another thing that I always do is start the pump before I crank the engine. That way if you have any seepage on the head gaskets when cold you have less of a chance of putting air into the system.
