Oil cooler leak

mx racer 161 · Dec 25, 2014

I have a 2000 f250 and the oil cooler is leaking i just seen it today. I plan on fixing but will be next week. I have to drive 200 miles to you guys think it will be alright to drive and just keep an eye on the oil.

Should be. As long as there is no oil and antifreeze mixing.

I'd be sure to keep an extra gallon of oil with me in case the o ring completely fails on you, but I wouldn't be too worried about it.

ic the o ring completely fails on it then you will be dead in the water.. it will pour out of it quicker then you can get it in... now if its just seeping and when it heats up it stops seeping then you will be ok.

Thanks guys. It made the trip fine with no issues. But the next day after i got home went to start and had a big puddle of oil under it so time to replace now.

Yep Good luck. Big bar clamp will help a bunch. And put a tarp under the truck, it's a messy job.

Yeah thats what i figured. Do you recommend getting a whole new assembly or just the orings and gaskets

Just orings and gaskets.
I used a ratchet strap.

:whs: Usually they leak the most when cold, those old o-ring going to be real brittle.

I ended up waiting a year before changing mine from the time it started leaking. It started midway through winter.
Only leaked when the temps got below a certain point, then would quit after running for a few minutes.
When I changed them, I already had the kit on hand, just forgot about it. Well it got cold again, and was leaking worse. Lol
Then when putting it back together something didn't look right. The filter bypass valve was gone. Still had to drive to work, so the next weekend I pulled it again. Lol
Fun times.

To squeeze the ends back on the cooler over those big o-rings. Easier than pushing or sitting. Ratchet strap would also work, I had the bar clamp handy.

I noticed a leak on mine so I monitored the coolant and oil level. Over a couple of months neither the coolant or oil showed any issues so I quite monitoring it. Last week I checked everything out again and the oil was barely registering. Well then I noticed it was all in my coolant. I instantly wanted to slap myself in the face. Lol So what steps should I take now? I know at a minimum I will have to change the gaskets and flush the coolant system throughly, any other suggestions? Things to look at or check out? Motor only has 30k miles on it.

Replace the o rings and gaskets with ford parts only. Then flush the coolant system. Use simple green or cascade.

Simple green and water? I assume I should let it heat up and dump it and do it all over again or just let it run? Thanks for the advice.

Yep simple green and water. Fill her up and drive it for a while to clean everything then dump and flush. You may have to do it a few times to get it clean. Here is a good flush write up. http://www.ford-trucks.com/forums/9...kflush-procedure-and-coolant-information.html
I would use a elc coolant when you fill up.

WILD_PHIL · Jun 3, 2015

Well thank you very much sir. I will be doing this in the morning.
