Hydraulic oil in radiator

[Svenxtian]

Hi all. New here from OZ, great info and forum congratulations guys.
I've read through and watched the video on engine oil in coolant/ frost plugs/head gasket etc, but my engine oil is quite black at the moment and the oil getting into the radiator is a honey colour (hydraulic). Any clues? B1550HST. Thanks

is there an oil cooler in the bottom of the radiator?

The oil cooler on this model is a smaller separate cooler.

Hi just found out my father topped up the radiator with hyd oil instead of coolant, after I'd stripped the hydraulic pump but before opening the head. :/ Another day....
Thanks

I could not imagine how hydraulic fluid was getting into the radiator..... I guess that shows we all tend to overlook the simplest solutions. Where's Forest Gump when you need him?

How is that possible??? Reminds me of the day a lady came to my trans shop with a complaint of trans fluid leaking on her foot..??%^*%$???? The cause,,, dirt dauber had stopped the vent up on the trans, as trans heats up, fluid expands and pushes fluid up the speedo cable into the dash,( this was before electronic cars), drips down from the dash onto her shoes. I was her hero for fixing that.
