Hello All, this is my first post and if its in the wrong spot, please let me know.
A little history, my father in law is about 90 and decided it was time to stop driving his 2002 Mercury Grand Marquis, my wife wanted to buy his car and get it away before he changed his mind, he has, well lost a bit in driving skills and sight.
So anyway, we live in Missouri, he lives in Louisiana, and this Mercury has lived on a dirt road for the last 12 years, dirt is being quite generous as it is really a turn row between fields and floods quite regularly. Mr. Russell did not spare the horses either, so I knew it might be a little rough. Yeah.
Driving about 10 hours, we got in late and caught up with family and got some sleep. The next day I got a good look at what I would be driving 500 plus miles home. Flat tires, check engine light, started it sounded like someone had thrown a shovel full of gravel and sand into a washing machine and set it on spin dry.
Oh boy. Oh and it was about 2000% humidity and a cool 89 degrees. They thought it was great, being from Missouri I was about to dissolve into a little puddle of sweat.
So I opened the hood and removed the belt. Its a Ford 4.6. I had never worked on one before but they really made it pretty nice to maintain. I grabbed the water pump pulley and it would move 1/4 inch either way. Not an encouraging start. The idler pulley and the tension pulley seemed to spin pretty smooth.
Now I figure your wondering if there was coolant coming out of the weep hole, nope. I looked at the engine and wondered how long it had not had coolant in it. I could not bring myself to remove the radiator cap. I started pulling the water pump. Yeah.
So Ford made it pretty easy to remove, four bolts and an o-ring seal, it might stick a little but it should pop right out. I tapped the hub. (I already pulled the pulley off) I smacked the hub. I looked to see if I had missed a bolt. I smacked it again, and again, and again, and again, and again, and again.
Ok, so I pulled the alternator to get a better look at the water pump. It had not so much as made a line around the housing. I looked again, four bolts. I asked my nephew, Zach, to look up a picture of the pump. The picture showed four bolts, little round housing, that is what I saw on the engine. Dang it.
"Ok Zach, put pressure here, not too much we don't want to break the engine". The little tab on the edge of the water pump snapped right off. Smack, smack, smack. Nothing.
"Ok, pry here while I hit it" Snap. There went the other tab I guess was supposed to be used to pry the water pump out.
So now I am getting a little irritated, I have changed many water pumps and this is becoming the most stubborn unit I have ever seen. SMACK, SMACK, SMACK. I deformed the hub a little. But I got a line to form around the water pump. Yeah baby it'll come out now.
Nope.
Fast forward, imagine a little cursing, lots of pounding and prying, mucho sweat -- Its out far enough to wedge screwdrivers on each side. The hub is deformed and we have about 1/16 of inch of movement out of the housing. I am sweating, my clothes are drenched. I start pounding on each screwdriver, alternating back and forth.
Slowly, it gives up, but it isn't moving like it should. I wedge a full blown pry bar under the hub and on the harmonic balancer. With quite a bit of force it pops loose, mostly. I had placed a pan to catch any fluid that might still be in the engine, and that was good thing because it was full of coolant!
The pump shaft was toast, and it had not leaked a bit! Of course now the water pump housing was broke and the hub was egg shaped, but dang Ford did a good job on that pump.
The reason it was so stubborn was that whoever put it in used some kind of sealant in addition to the o-ring around the edge. Combined with age, it was stuck.
So it was off to town to get parts, but that is another story. Oh and I have to drive 500 plus miles tomorrow, in this car.
