Oh....that's not good.
Justrucking2 and Hurst Thank this. -
Oh no... That is not good. Looks like someone mixed coolants. The water jacket in your motor may possibly look as bad. I don't think a flush is going to fix this mess. I would say a new radiator and pull the motor apart. Have you removed the thermostat yet? I would do that and see how that looks. If there is a coolant filter on there, I am not that well versed on Cat's, but there should be one on there too... If there is, pull that too and see what it looks like, normally located close to the water pump, looks like a car oil filter if it is there.

Looks like old geled up coolant. Really old.
Either it hasnt been flushed in a long time or the truck sat for a really long time.
I've bought old cars like this. I usually tore the motor down and flushed it out in a parts cleaner with solvent.
Guessing that is not really an option or something you want to hear. But there is no telling how many passages are clogged, how bad the clogs are, what condition the thermostat is in. Maybe run some high pressure water through it and see how much gunk comes out.
Thats not something I would want to see in a truck.
Hurstnax and Justrucking2 Thank this. -
Could it be a bad oil cooler? The radiator is all new with waterpump and thrmostat, well i dont think its new nomore after all the clogged up #### i found in it
Roger McG Thanks this. -

The gunk wasnt there when i replaced the radiator and air cooler,, poped up after the red coolant was added then 2 months later thats when it showed up in the reservoir since the driver kept addin anti freeze due to a leak he noticed inside the reservoir looked like red hard clay

YUUUUUUPP!!!
someone mixed red/green coolant.
Start with the coolant flush cleaner, and rinse, repeat a few times, before going crazy...
- best case: flush & be done
- worse case: replace radiator/water pump impeller/ hoses
- worst case: open up block (not likely)
Rubberens Thanks this. -
