Coolant leak, thinking water pump

Car is my cousin's 00 taurus 3.0 that has been neglected. I went to take a look at some things for him today, brake leak, coolant leak, power steering leak. I brought my stant pressure tester and pumped it up to 16 PSI and it seemed to hold for the 5-10 minutes I had it on there. Didn't see any major leaks but when I crawled under the car I saw some coolant dripping from the exhaust on the passenger side and then a few signs of coolant dripping down the engine coming from the area of the water pump. Is it a pretty good assumption to say the water pump is shot or is there something else in the area of the water pump that I should be checking out?

Thanks for any advice with this.

the water pumps on the bulls are horrible. the cooling system needs to be maintained with new fluid every 2 yrs. coolant on the exhaust would make me look at freeze plugs and head gasket.

It is dripping down the passanger side of the engine and then onto the exhaust. I don't think it is a head gasket because it was holding pressure with the stant hooked up. Might be freeze plug but I didn't see any up there. It was coming from above the oil pan and looks to be coming from right about where the water pump is. I have a uview dye kit that I can put in but with the system holding pressure and the drip coming from the area of the water pump I figured it was a slow drip out the weep hole on the pump?

its possible that the water pump has a broken vain blocking the output or input hoses giving you a false reading on the pressure test. i would die test and see what you can see.

Which engine is in this car?

If it is the Vulcan OHV engine, it is quite possible the timing chain cover gasket is leaking.

Check the VIN number, eighth place letter. If it is a 'U', it is the OHV.

I just asked him to check the vin.

Is there a way to tell if it's the timing cover or the water pump? I couldn't really see up in there to well to see exactly where it is coming from.

Also lets pretend that it is the cover leaking, what all is involved in fixing that? Is it something I can do along with the water pump fairly easy while I got everything out of the way to do the water pump?

I know it is the flex fuel engine which while I was just checking advance auto website says the vin is 2, the OHV is U and the DOHV is S so according to them the vin is 2. Does that help with the timing cover issue at all?

Flex Fuel is the same engine design as Vulcan

So there is a strong possibility that there is leakage between the block and the timing chain cover.

If it is not leaking from the pump, check this area out. There is a comprehensive thread describing this problem and the repair action. I also wrote a wiki on the repair. It is for the Gen IV (model year 2000+) and should cover your car.

If you can't positively identify this as the problem, take it to a mechanic or Ford dealership service and have them look at it.

I had a similar problem about 2 months ago on my 01 , at first I thought it was the water pump, so i replaced it with a brand new one, and it was still leaking coolant, I checked all the hoses and everything looked fine, come to find out it was the overflow tank was leaking from the bottom . replaced it and it stopped leaking. check the coolant overflow tank, that could be your problem. I have seen a lot of early 2000s with the same problem, the plastic tank cracks and it starts leaking.
