I just got a CSI Water pump. Is it suppsed to come with the freeze plug? What will work instead of it, or is it something I can buy at home depot?

 

It should come with the plug for the waterpump (but not the timing cover).

 

I got the freeze plug for the wp housing with mine recently, I ordered from Jegs. If it's not there you could call them and ask them to send you one or just get one at an auto parts store, I'm not sure of the size but I've seen it posted here. I doubt Home Depot would have something like that but who knows.

 

That would be an auto supply store item not Home Depot...
If you need it I can go find one and measure it for you I have one around here somewhere..
