Radiator leak @ 45k miles

[po-po 5.0]

I have a job #2 truck, and just started leaving little puddles of coolant on the ground. The truck has 45k miles, is a new rad going to be covered under the powertrain warranty?

Might be the o-rings for the upper and lower radiator hoses. I just had to replace mine yesterday (44,000 miles). Not a warranty claim.

If its just the o-rings I wouldn't be concerned. What I am concerned about is dropping $700 on a new rad.

My job3 08 just started leaking. Driver side bottom where aluminu
meets plastic so assume this is not oring but possible crack that I have read about. Where did your drip come from?

My t-stat was leaking at 44,000 miles as well. Go to Gullo Ford in Conroe. They warrantied it. Assuming that is where it is leaking.

I agree. Mine leaked at 40k and it was a fluctuating tstat and I did not have the venturi T TSB. Either one of these problems allows the radiator to be replaced under warranty.

Mine job1 just started doing this as well... leaking from the same place... drip on the ground, running from the frame rail, which is being dripped onto by the bottom drivers side corner of the radiator. I notice my engine coolant temps seem to fluctuate a lot more now too... used to hold at 190F pretty steady... and now it slowly makes it up to like 196-198F, (empty, no load) then goes back down to 190-192 quickly.

35,700mi... better get it in the shop I guess!

I noticed my temp is doing the same lately, no leak yet though. Job 1, 26K and original rad.

Ford has extended the warranty on the radiators on these trucks. Heres a thread on FTE
All 6.4 Radiators are now covered for 5yr/100000 miles - Ford Truck Enthusiasts Forums

Mine started leaking at 43k. My thermostat locked up on a muddy back road one day and blew the coolant line off the passenger side of the truck that goes into the engine. Needless to say it puked out all my fluid in about 2 seconds and i never even knew it was happening untill the temp light came on. Its a well known problem about these truck to have coolant issues and its a good idea to walk around once a week and look for leaking coolant. Id hate for you to have to buy 70$ worth of coolant like i had to. (Its expensive from a conveinence store in the middle of nowhere!) Anyways since ford knows its an issue take it in ASAP.

That is incorrect.

There is two different causal numbers on the radiator replacement TSB.

If the thermostat functionality is okay, the TSB is causal numbered to 8009, which is the radiator, and is only covered after 3/36. If the thermostats are hooped, the TSB is causal to 8575, which is covered under diesel/powertrain coverage.
