Puking coolant, high oil temps

[nick28]

Hello,

Looking for some feedback on some problems I had on 800 mile trip today with my 2008 job 1 f350.

Radiator has had a small leak for sometime now, coolant temps/oil temps always in range. I mostly city drive.

Today towing 18ft open trailer, I noticed my EOT climbing, it reached 230 the Spartan alerted me, I eased off (was running around 80), it almost immediately drops back to 210-212 range. ECT's are 194-200 all day. Oil temps range from 198 to 235 once, mostly consistent around 212-215. I noticed when I stopped for fuel, I had puked some coolant out of the degas bottle. I topped it off and it seemed to help with the temperature fluctuations. But they varied all day, and of course pushing uphill etc it would climb quicker. It puked coolant a few more times throughout the day as well.

I read anywhere from headgaskets, to oil cooler, to degas cap, to all of the above lol

Truck has 190K, deleted, Spartan tuner, just had up pipes replaced this week, and I changed oil before I headed out on my trip.

Can anyone point me in the right direction.
Thanks
Nick

I would lean towards a bad oil cooler.

Update today, I went out this morning before starting truck, coolant level was down below lower hose. Cap had some pressure upon taking it off, topped it to the cold fill. Started truck let it warm up, drove to parts store to get new cap. It puked a tiny amount on the drive to parts store ~5 miles, under 50 mph. Temps were fine.

Put new cap on...

Got on the interstate, steadily accelerated up to about 90mph trailer is still hooked up. Oil temp increased to around 218. Got to my shop to drop trailer, raised hood, no puking, normal coolant level.

Truck runs fine, Im curious to the ECT/EOT spread under load. Should it remain within the same 6-10 degree spread all the time?

They will spread more than 10 under load, mostly dependent on RPM.
90 with a trailer, glad you dont live near me.

Thanks, that was my assumption. So far with the new cap everything seems to be back to normal. No pressure under cap when cold in the am, and normal coolant levels.

It was a short 4 mile burst between exits, 8 am, I passed one semi. I was unloaded.

why are you towing 90mph with a trailer? no truck is going to last driving 80-90 all the time with a trailer hooked up to it, considering it sounds like you are running the **** out of it.

 

[nick28]

I was looking for suggestions to my issues, not lessons on how to drive. Its an open car trailer that weighs 1800 lbs. The trip down I was empty running 75-80, on the way back loaded I may have been 4500 lbs and was running 70 mph.

The 90 mph comment was a short run up to 90 and then back off to see if I could replicate the issues with the new cap. Again unloaded.

Its not like I run 80 mph all day long with a trailer hooked behind me everyday. I'm positive these trucks are more than capable of towing a light load at 75-80 mph with no ill effects on the engine.

Don't know why they are making a big deal out of your speed... just look over it.

Sounds like to me you're in need of at least an oil cooler but your head gaskets are probably blown too with it pushing coolant.
