Anyone else having any issues with the large plug on the back coming out at high rpms? The new one is new not a remanufactured. Hopefully it will last a little longer.

I just had this exact problem with a new AutoZone pump, I had about 10 min on It and it came apart. I bought a new Delco off rock auto for around $100. I'm installing it tomorrow

Makes sense though, higher rpms means increased pressure. If you have any restriction in flow throughout the system this could cause an increase in pressure at the pump which results in blowing the back out of it as the weak point.

Never had an issue. But I've only ran GM water pumps. No fancy fittings, just good ol stock configuration.

I have been hearing of guys welding a plate to the back of the pump to hold the plug in.

7+ years between a stock 6.0 & now an L33 5.3, I've never had to do anything fancy with the water pump. BUT I don't have all the horse power some of the folks do either......so what do I know! LOL

Yeah I think I have discussed this with you or Patrick. 16 doesn't restrict the flow of coolant anymore than the thermostat. Also I run what wod runs.

Does anyone see a problem with this for my steam port? I wouldn't think it would build anymore pressure but wanted to ask the pros

Mine is done that way and attached to the crossover vent tube. It is designed to Suck out the air from the crossover steam ports.

I installed this adapter in the center of my upper radiator hose. I run my automatic fan controller temp sensor to it and I drilled and tapped another hole in it to connect my steam port hose to.

I tapped my pump on my first swap, but used this on the last one I did. Just add an npt nipple.30th6 said:

I've ran my new Delco pump tapped for the steam port for a hour or so with full throttle runs with no problems.
No more AutoZone water pumps for me
