So it looks like I need a new water pump, problem is that two are listed depending on engine number. I already looked under the car, I don't see it. Any other way to find it? Vin #?

Not sure if it makes a difference, but I know that my chassis number is the later one because when I ordered the harness that's what I needed.

Thanks:surrender:

Got it all figured out; for the next person with the same issue on a 1995 C288here is what I found.

The water pump I ordered was for the later engine number
The only difference I could find between the two waterpumps is that the earlier version has a port on the backside (facing the firewall when installed). I believe this is for some type of additional cooler.
My water pump did not have any provisions to attach anything on that side, which matched the later version pumps.

So fitting on backside = earlier version/engine number
no fitting = later version/engine number

If you have any question as to which pump you have, it's pretty easy to see the backside of the pump, just pop the hood and take a look.
