HELP! ADVICE! Water pump leak???

I HAVE A MAJOR AAAHHHHhhhhh POOP! My 99 Taurus SE with 12 valve and 170Kmiles decided to take a leak! And yes, the coolant is rusty looking but has been that way now since I got the car 3 years ago...........it does seem a little worse now though.

I noticed the water was coming from under where the pump is located. Took it to my friendly garage, was told that to change this think it was going to cost $1000!!! no, i WILL NOT PUMP THAT AMOUNT OF $$$$ into my lovable Taurus. But the story gets more confusing. He went on to say the water was coming out between the timing chain cover and teh engine block so not only did the pump need replacement, but at a minimum the timing chain cover will need a new gasket.

I was bewildered. I asked if water was getting into the oil.... no. But how can the water coolant pump be part of the oil circuit??? I did not get a good answer to that question. But presume the water is coming from a leak between the timing chain cover and the engine bolck, how the heck could that happen??

PLEASE--- I need some advice. I have a "shade tree mechanic" who wants to do the work, cost will be much less but again another but. Suppose this gets to be a far more complicated job because water is getting out the timing cover???

DOES THIS MAKE SENSE????:wtf2:

Thanks--

Usually, if its the cover leaking (red arrows) it will run down the left or the right of the cover. If its leaking at water pump snout (blue arrow), its the pump.

If it does turn out to be the cover, with that many miles, be sure to have the chain and seal replaced while its apart.

Thanks folks for yor fine description of what is happening. I need to follow up with a couple of more questions.

Is the waterpump acting as a cover to the timeing chain or is there another cover for the chain. Do I need to purchase both a timecover and a pump?

Timing chain-- I am guessing that the gear that eventually drives the cam shaft is removed via holding bolts and does not need a gear puller. Yes, I do know there is a lot of miles on the engine so changing the chain is good adivce. But there is not much room in there to work and there is a good chance to screw up the mechanical timing.

I think I am going to attack this thing along with my shade tree guy. Anything I need to watch out for?

Thanks again!!!!!!!!!!!!

The water pump is bolted to the chain cover. If it is in fact leaking at the cover, you'll need to replace the gasket that's shown in the illustration.

You'll remove the timing chain by unbolting the cam gear (top) but the bottom gear will require a claw type puller. I have in the past used a chisel and just broke the bottom gear but you need to be careful not to damage the crank snout.

Another thing to look for, when you remove the harmonic balancer, have a look where the seal rides and make sure there is not a groove cut from wear. If so, you'll need a balancer sleeve kit.

I'll try to get you some step by step instructions and post back.

Article 01-12-4 is being republished in its entirety to update the Service Parts involved.
ISSUE
A service oil pan gasket and a new service oil pan gasket kit has been released for all 3.0L-2V "Vulcan" engines built from 1986-2001. The new service (only) gasket eliminates the need to attach the gasket to the block with a contact adhesive thus eliminating gasket creep (sideways) movement during installation. Slightly longer fasteners (bolts) have also been released and packaged in the kit. The old bolts must be replaced with the new ones. The new gasket is installed by placing it on the oil pan and not gluing it to the block. The bolts will still have to be torqued twice during installation and once after the engine has reached operating temperature. The torque value for the bolts has not changed and is the same as listed in the Workshop Manuals.

ACTION
Install the new service Oil Pan Gasket Service Kit (2U7Z-6710-AA). Refer to the following Service Procedure for details.

SERVICE PROCEDURE

Use the following revised Oil Pan Gasket kit (2U7Z-6710-AA) installation procedure.
1. Remove the oil pan as instructed in the appropriate model year Service Work Shop Manual and discard the old gasket and fasteners (bolts).

2. Clean and inspect both the oil pan and the engine block mounting surface. Carefully and thoroughly remove all traces of the old RTV sealant from the oil pan and engine block. Refer to the Workshop Manual for the correct metal surface cleaner.



3. Apply beads of Silicone Gasket and Sealant (F7AZ-19554-EA), or equivalent meeting Ford specification (WSE-M4G323-A4) to the front cover and rear bearing cap-to-block parting lines (Figure 2).

4. Install the gasket on the oil pan, being careful not to damage the plastic tabs.



5. Install the oil pan to the engine block with the new fastener (bolts) packaged in the service kit, run down all the bolts by hand (Figure 1).

NOTE THE TWO CORNER BOLTS NEAR THE FRONT OF THE ENGINE ARE A DIFFERENT LENGTH.

6. Tighten the four (4) corner bolts first to 106 Lb-in (12 N.m).

7. Tighten the remaining fourteen (14) bolts from back to front (alternating from side to side) to 106 Lb-in (12 N.m). Figure 1.

8. Check all the bolts by retightening to the same torque specification.

9. Finish installing the oil pan per appropriate model year and vehicle application Workshop Manual procedure.

10. Refill engine with oil, start engine and allow it to reach operating temperature. The cooling fan should cycle at least one time. Stop the engine and retighten (torque) all the oil pan bolts to 106 Lb-in (12 N.m).

11. Inspect for oil leaks.

HOLY SMOKY ANDY!!!!

JWKO---That is one hell_of_a_job!!! No way am I going through all that. Heck the car has 170K on it and is 11 years old. If I can pull the pump, replace the timing gasket that is about the extent of what I am willing to expend.

If I can get another 25+K on it then it is worth a new pump. Beyond that, I would rather purchase something with lower milage and start over.

Now please do not misinterpret my appreciation for the task you just described. But you are a skilled mechanic who is able to do task A in 1/4 time as me and then move onto task B. Even with the simpler task of changing only the pump and timing gasket, I will run a risk of screwing up something.

I'm a shadetree mechanic only. lol

The only reason I posted the oil pan gasket info is it states in the R & R of the timing cover to install a new gasket. In reality, you "probably" can get away without changing it. But the instructions are there if you need em.

I don't think you'll have any trouble changing out the water pump and the cover gasket. The hardest part will be having enough room in there to work. Removing the coolant tank will help a lot.
 
#12 ·
Thanks again JWKO! Yes, removing the coolant tank is a good suggestion. It amy also help if I jack the car, remove the left wheel and the splash guard. I might have better access to the pump. Not much is going to happen before next week but I certainly do plan to attempt the job. OH--- thanks again for all the pictorials. They will help a great deal.

My 2000 Taurus POS is leaking coolant as well. I can't see the origin of the leak, but it appears to be coming from the front, firewall side of the engine. This leads me to believe the timing cover gasket is the culprit. I'm confident I can do the repair myself, but my only concern is removing the crankshaft damper. Any tips or tricks I should know about? Is it a reverse threaded bolt?
 
#18 ·
I'm working on my 2000 Taurus POS right now. Yes, you have to drop the oil pan. Therefore, you also have to drop the exhaust Y-pipe. Luckily I was able to drop it down without too much trouble. The two bolts on the firewall side are a little tricky due to limited space. I'd suggest spraying them with PB Blaster or equivalent and let it soak in overnight. You don't need to completely remove it, just lower it enough to remove the pan. You don't have to take off the power steering pump bracket. Once you get it all apart, you should probably also install a new timing chain set as well as a new water pump. My timing chain is really loose. You'll also need a new oil pan gasket. The attached picture show where mine was leaking.
