So yesterday I was driving my 1995 Civic DX and I notice that the temperature gauge was rising. I opened the hood, opened the coolant reservuar and it was empty with steam coming out of it. I filled it up, opened radiator cap and filled that up as well - used almost the entire bottle of antifreeze. Then I pulled the car away and there was a huge antifreeze spot on the ground, right around where the water pump is. I made it home, and when I got out I saw a trail of antifreeze on the road where I was driving, and. This morning there's was huge paddle of antifreeze underneath the car. It is leaking on the left side of the car, and as far as I know the only thing there that it could leak from is the water pump. I don't think there are any hoses in there that could be leaking.

Right now I have 145k on the car, last time I replaced water pump and timing belt was at 80k, so they both have 65k on them. I am wondering what would be the difference in labor cost is I was to replace the water pump only or if I was to replace both the pump and the timing belt. The Civic is my beater car, so I would like to invest as little as possible. Is there a way to stop the water pump leak without replacing it?

Also, yesterday when I saw the problem it was kind of dark out, so I couldn't see clearly, but when I checked the engine oil it seemed clean, I didn't see any antifreeze in it, but the antifreeze looked and smelled kind of funky, might have been some oil in it, but im not positive. I will check it out when I get home. And while I'm not certain about the oil, the antifreeze also had a lot of small particles in it, almost like sand or metal dust - what the hell could that be?
