Something in my coolant.

Jeff H · Nov 7, 2012

Is there any way diesel fuel could get into the cooling system? 2002 with 295,214 miles.

Injector Cup

Jeff H · Nov 7, 2012

Is the injector cup replaceable or is it part of the injector? These are the original stock injectors.

Yes, cups are replaceable. Rosewood diesel has a great tool for doing this, the tool,cups, and new injector o rings is about $500 iirc. Its not a bad job at all with the right tool.

:whs:

Riff Raff also has the tool to rent and parts

Stock injectors?

If so, it might would be smarter to go ahead with a new set of injectors while you're already in there.

are you SURE its fuel?
Post a pic

Jeff H · Nov 7, 2012

Got a sample and had it tested. It's not diesel.

Spatel23 · Nov 7, 2012

I really didnt think it would be. Could the same place not tell you if it was oil?

I think its oil, which is a bad oil cooler. Easy fix with a new gasket kit.

Still like to see that picture though.

Jeff H · Nov 13, 2012

Now it looks like oil. Are there instructions on here on how to change the gaskets on the oil cooler?

it didn't look like this before. I've flushed all the coolant out twice it is just water now.

here is a PDF on how to do it,,

Jeff H · Nov 16, 2012

Could this be anything else other than the oil cooler. Not getting any coolant in the oil. Would it be better to buy the cooler, gaskets, and o-rings or just the gaskets and o-rings? Can get the cooler and all gaskets and o-rings from Ford for $300.

Unless the cooler is rotted there is no need to replace it unless you just want to.

If it looks like someone hocked a loogie in your antifreeze, it's probably fuel from leaky injector cups.

I don't think so....

Jeff H · Nov 17, 2012

It smells weird and it does look like someone hocked a loogie in there.

Southmike · Nov 20, 2012

there is a video of an oil cooler rebuild...done by cody iirc.

might just be pics all i remember is some comment about dont look at the bald spot...lol

Two bolts up front on the flange, three in the back by the oil filter. Drain the coolant, drop the oil filter then unbolt everything. Remove the oil cooler, pop the end caps off, clean everything up good, inspect the cooler tube to see if it is rotted. If not then replace the o-rings, clean the mating surfaces of the flanges and mounting surfaces on engine. Be sure to use assembly lube on the o-rings so you don't damage them. Use a ratchet strap to "pull" the ends down firmly on the tube. Re-install it into the truck with new gaskets.
