Repeated Waterpump Fails and frequent no Heat on 16'

[Bigbadbull]

So over the past 6 months I have had to have 3 water pumps replaced , as well as the HVAC system serviced due to no coolant or a line popping off after the water pump being replaced. In 13 months we have had the vehicle serviced for the same thing 5 times, all under warranty. All by the same Ford service department.

We bought the truck with 12k on it and it now has like 32500 on it. Any suggestions on what could be causing the over pressurization of the system?

Any suggestions on what the next course of action to take is? I don not want to have to call Ford Customer service , as it would look badly on the dealer service department, and they have been super helpful with our other Fords. I have requested the Service Department Manager have a look at the case and its issues.

Thanks in advance for any suggestions.

As long as you are under warranty, you don't touch it. Let FOMOCO take the hit in the wallet. You should write a nice letter to a Ford Customer Service rep that details the issue, and at the same time applauds the dealer, to let them know the vehicle has an issue that isn't being resolved and you're eventually going to be out of warranty and what are they going to do about it, blah blah blah.

I would have blown a blood vessel on the second replacement. Your motor isn't venting somehow. As nice as their are, they can't diagnose. You need to get ahold of Ford now. They might just replace the vehicle if they can't fix it. I've never heard of water pumps blowing out, especially Ford ones. Apparently theirs no overheat issues or you'd know it, this is a new one, and I've thought I heard them all. Anyone else here had a problem like this.

I just reread your tag line, didn't pay attention first time. You very likely have one of the two heater cores plugged, if your getting no heat. That or a heater valve that's sticking. Surprised your not overheating, or running excessively cold on your engine.

Yeah, there's some blockage there somewhere. Several places to look, but that's the dealer's problem. He should backflush the block and heater core and do some diagnosing. Ford engineering should help him with this after they get tired of paying for water pumps.

 

[powerboatr]

agree a heater core could be plugged....what failed the first pump? sounds like something is acting like a plug.
get on horn to ford corporate as well as politely pressing the dealer to stop the REPLACE and go, with SEARCH out the reason, then replace parts...

good luck

Just for laughs and giggles, what's the name and location of that "Dealer"? Our other members probably would like to know. I know I'd drive somewhere else for repair.

It's a shame that a plugged heater core could cause a problem other than no heat in cab.
I have bypassed a good number when they started leaking and never had any other issues.
Not familial with a 16 water pump but the original modular ones are probably the best water pump I have ever seen.

I heard from the dealer yesterday, no clue on the cause as the system is pressure testing ok. Said the tech said it started roughly so now they are looking to see if the coolant is leaking other more "vital areas". I just had the oil changed last week so my fingers are crossed that its not that. There is no obvious puddling of antifreeze in the engine bay or the under engine air deflector as well.

3 of the same failures, with in a year qualifies as a lemon.

Depends on the state most require the issue to occur within the first 90 days of purchase. Plus they bought used which very few states have any lemon laws for used vehicles.

As for feeling bad for the dealer, DON’T.
3 water pump replacements in a years. I would not have taken it back to them for the 3rd time.

Who is saying the water pumps have failed?
What information are they using to determine the pump has failed?
What is the vehicle doing from your viewpoint?

Wow that's unusual. Not sure what the issue is but man that would kill my confidence in the vehicle going forward. What happens is if it fails again over a year from now?

See if Ford can provide you with an extended Factory backed warranty on these repairs or for the whole vehicle for FREE. Who knows what else this would affect?

I would go to the service manager, then dealer manager, then Ford's regional manager to see what they can do for you as a dedicated customer.

With it being a 16 sold with only 12,000 miles on it, It makes me wonder if the vehicle had problems before and Ford bought it back, repaired it (supposedly) and put it back out for sale? Can the dealer pull up it's previous to you service records?

Evidently I've not spent much time under the hood of my Expedion. Which I'm OK with.

This week I've learned there is an electric pump that circulates water to the rear HVAC. Was news to me.

Several months ago I did replace what I thought was the heater hose on the passenger side- A line with a tee in it to feed water to the heater core at the firewall. So I struggle to understand - if a heater core is blocked, how and why would the water pump care? The water pump is still circulating fluid around the block and radiator.

Highways don't shut down when one exit ramp is closed is my pea-brain analogy.

Whats the PSI on your overflow box cap?

 

[jeff kushner]

I agree with those who have asked, what were the symptoms you noticed as a driver?

What you have said runs contrary to all evidence we have seen with Ford Expy pumps....so we're curious what's REALLY going on. Has the dealer found acquiescence in a client they keep going back to or is something really wrong?

I wonder if the drain is weeping and they are using that as evidence of a "Bad pump"?

Im Stamp on this one.

Whats up with the water pump? Leaking? Not moving fluid?

 

[powerboatr]

i had no idea there was a pump for the rear heater...really
i need to crawl around bit under the vehicle and look around


my bus is 40 feet long and water pump is one end and the heater core is on the other.

 

[1955moose]

I agree with a plugged heater core should not affect water pump function. I'm going out on a limb here, but if that dealer keeps changing the pumps, I'm assuming their leaking. That and no heat intermittently, is why I came up with the plugged core, or some obstruction. Is this vehicle overheating at any time? You never said it did. Another thing that popped into my pea brain, what about electrolysis in motor blocking flow, causing the excessive pressure. Could be a weird casting flaw that they didn't catch when they built it. Whatever it is, this ones going to be a tough diagnostic.

If the coolant is a mix using distilled water, electrolysis is a mute point.
Excessive pressure should open the relief on the cap and vent the excess pressure.

Better to wait on the OP for info on what the vehicle is doing to cause concern.

We're only up to 20 posts. Wouldn't it be funny if something stupid like a bad cap or something simple is causing this. Usually is. I was reading online about a bent pulley on Volkswagens causing failures of pumps. Something to consider having shop check before they pop a 4th one on.
