Is a little end play in the water pump bad news?

I have developed a slight rattle noise from the engine during the last few times I drove the car. It usually goes away as I increase RPM's. Ive checked everything and cant seem to figure where its coming from but I notice a very slight play in the water pump when I move the fan back and forth. Would there usually be a slight play that I never noticed on this or should it be dead solid?

There should be no play.

Does it also make noise while in park ? Then that could be it.

I always tell the customers at Autozone....if it (waterpump) is squeaking or leaking, it is time to get a new one. I wish I could the number of people that think the weep hole is a made up thing.

I had one pump go out due to a clutch fan, had oil everywhere.

Re: Is a little end play in the water pump bad news?

Water pumps end bearings tend to spit the dumby with a little play then usually not long after that and a good rev, leak.
This is caused by over tight side tension of the belt and or fan clutch bearings gone, and out of balance.
I was replacing pumps with good clutch every couple yrs..I even rebuilt one my self with upgraded industrial bearings...(not worth the effort)
Anyway quite Some yrs back I decided to slacken off the fan belt from stock, just enough so when one put the boot in it would sqwell a little.
Presto the water pumps just would not wear out....If I was going out to run a quarter mile or knew I would be hammering it over a long trip of quite a few 100s of miles, I just tighten a little.

My Spelling is not incorrect...it is creative
