Job 1 rad leak....after 47000.

[Tsgs69400]

Well guys, i dodged the bullet for a long time, but it finally happened. I found a tiny drip from the bottom of my drivers side rad seam.
I knew it would happen, but i just wish it happened sooner. I am out of my 5 yr 60,000 warranty. Would the 100,000 powertrain warranty cover it?
Otherwise, how bad is the change to do yourself?

Mine went for a dump last week at 110k miles.

There's a TSB regarding radiator failure coverage. It depends on what part failed to cause the radiator to leak if it's covered or not. There's also prior approval required now for radiator replacement.

Causal 8590 is the O-ring in the coolant hose(s) and if I recall, (OASIS is down right now so I can't check) it is covered under powertrain. So if your rad is leaking because one of the rad hose o-rings went for a ****, then I believe it is covered.

If the rad is leaking just because they're junk and poorly made (likely the case), and you're out of basic warranty, you're on your own.

Being a Job 1 truck you're probably getting to be close on time for warranty as well.

As for doing it yourself, if you've never done one before, plan for 4-6 hours to change it.

It can be done in under an hour, but at the peak of failure I was changing 7-10 of them a week lol.

Thanks for the info. And yes it is leaking from the tank seam and not the hose connection. You are also correct that i am out of the 5 year warranty by about 5 months.
I am quite capable, i do all my own work when time allows. I was basically finding out if it was even worth having the dealer check it out an get raiped for somthin i can do myself.

It's not that bad of a swap, I personally pull both batteries out just because it makes it easier to get at the upper rad support rubbers, and it takes like 30 seconds to pull them out.

Ok, i gotcha. I had all that out last year when i made my cac and egr delete.
Now that i have the egr delete, how do u feel about the venturri t being eliminated?
Should i drill and tap one of the plugs for a fitting to put the venturri back in play?

I've had my venturi tee removed for over a year now. Rad just went for a dump last week, so take it for what it's worth LOL.

I'd slam thermostats in it while you've got it apart for the time it's gonna take you, since you've already got the cooling system open.

If you have EGR delete then definitely do thermostats at the same time. Get a VistaPro radiator too not a junky Ford one. Get the updated white end hoses as well, here is the part #'s for the radiator, hoses and thermostats, if you have the time and tools do the water pump as well so you can check for cavitation;

2008 F350 6.4L Cooling System Refresh

Thanks guys, I got a price from my ford parts dept for rad, hoses, and stats for around $850.
He is checking with their diesel tech to see if its worth it to have them check into the hyper extended stats.
Id like to check out the water pump but idk right now. Its been about 5* here the last couple days and im not sure if i want to go that deep considering my coolant tests out fine on the test strips.

My truck has 48,000 miles and started leaking at about 47,000 also. Brought it to the dealer and was told the rad is not covered under the power train warranty. This was after i had to pay them $250 to diagnose that my radiator was leaking when anyone with eyes could clearly see where the leak was. My leak is coming from the driverside seam as well. It drips here and there and then disappears for a few weeks and then maybe a few drips again here and there. I will replace it eventually but its too cold here right now to start playing with that so it can wait untill spring
