Water pump and radiator leak

I've been battling an intermittent coolant leak for a few thousand miles. I never could pinpoint where it was coming from, but I knew it was behind the fan around the water pump area. I finally took it to the dealership to diagnose. They agreed it was the water pump, but the radiator was also apparently leaking. I hadn't seen the radiator leak even though I've been looking for a while.

Even though I'm deleted, they're warrantying the water pump. But they're not covering the radiator under warranty. Maybe because I'm at 40k miles? Either way, I'm having them fix both problems while they're in there. Total cost for the radiator replacement is $1576. My dealership is also providing a loaner F-150 at no charge.

Waterpump is covered under the engine warranty, while the radiator is under the 3yr/36K. Seems like they might be able to give you a break on the radiator labor, since they have to do some of the same work to replace the waterpump. Might be worth the ask? Too bad you didnt get it into the dealer 4k miles sooner....

I believe the new replacement radiators leave out the top driver side bolt to prevent stressing the end cap.

I asked about the additional labor for the radiator. They said with water pump replacements they just remove the fan shroud and fan and work behind the radiator. There isn't a whole lot of cross over. I find that a little hard to believe, but I've never done it. I imagine the water pump replacement without the radiator in the way will certainly make the warranty work cheaper!

This new radiator should come with a warranty, correct? It will get a thorough once-over before that warranty period ends.

I just got everything back. I didn't check to see which bolts were on there from the factory, but it looks bolted up completely now.

Anybody know where the coolant level should be? Is it supposed to be between Min and Max when it's hot or cold?

Mine sits just under full line when cold about 3/4” above when at op temp.

I thought it should. That's what the manual says and that's where mine sat when new. After leaving the dealer, mine doesn't even register on the tank when warm.

Not surprising. it will take awhile to burp all the air out of the system. you'll have to add some for sure.

dealer should have given you the balance of the container that was left over knowing that you will need more.

You can get it at walmart

I had two gallons mixed up sitting on the shelf from when it was leaking. I've used a gallon so far topping the system off.

There is still a ton of coolant dropping on the suspension parts and onto the ground. Either the tech didn't get everything buttoned up correctly or it's residue from pulling the parts out.

spay it all down so you can monitor it. Then maybe wipe it with grease rags.

That doesn't seem right. When I had both replaced, I had to add maybe a half gallon. I second the idea of going to a carwash with underside wash to get it all off, then see where things stand. Doesn't sound like the tech pressure tested the system...

Deuce - Where was your water pump leaking from?

Walked out to start the truck this morning and found this.


Looking up from the bottom of the engine. Looks like it's dripping from the area above the lower radiator hose, which I assume is the water pump. I've also noticed an occasional slight whining sound as well.

Here is what mine looked like for a known primary water pump failure.

To update my last post, I filled out the post-service survey very honestly. The dealership called me to discuss the issues I had with cleanliness and topping off the system. I'm not sure it'll do any good. I also noticed the tech scratched the crap out of the top of my painted bumper while messing with the grill. **** poor. So far I have not had any leaks since the repairs were made.

Yes, that looks like where mine was dripping from. The drips followed all the suspension components before dropping on the ground so the point of puddle would vary. It looks like you might have an oil leak as well?
