Lamborghini R6 190 /Deutz Fahr Agroton 6190 dirty coolant and leak problem

[RaulP]

Noob me, before I took the head down I checked the oil cooler....aaaaand guess what? filing a hole with water made all 3 holes full of water, so it's destroyed. I have taken the head down and there's no sign of damage of the headgasket. It's 5 layer steel and seems bullet proof. I might taken the head down for nothing...But still, why does it build up pressure? maybe the radiator is clogged?

Does it still do this after replacing the oil cooler? I’d have thought that would have sorted it.

I dont know yet, because I already had taken off the cylinder head just be sure that the gasket isn't cracked. And it isn't. Still, I dont understand why did pressure was built. Replaced the headgasket and tomorrow i hope I will start the engine.

I suspect it will be fine with the new oil cooler.

I've finally finished the job...It seems the only issue was the oil cooler. After many flushes water is clean and the tractor seems to work just fine.
Local Deutz dealer made me an offer of about 1000 euros for the cooler box (oem SDF)
Local Fendt dealer made me a better offer for the same part, oem sdf, about 500 euro
Bought NRF aftermarket with 180 euro
NRF 31862 for who asks

Final conclusion, watch out for the OIL COOLER BOX!!!

Make sure that the coolant you use meets the Deutz standards. It may, like JD, require some fancy modified organic acid coolant. I don’t know for sure because my knowledge of these engines is limited, even though I struck gold with this particular issue.

Well I'm glad I'm not the only one who didn't know coolant needed changing. I'd never done it either and had dirty water in my massey and had to change the head gasket recently because of it. And a water pump
Seems fine now. Got a tractor that's almost 30 years old and has never had coolant changed and it's fine 15 year old tractor sh1!s the bed because of it

Look on the bright side, you've likely saved thousands by not replacing coolant for a total of 45 tractor years and there's every chance the head gasket would have failed at some point anyway.

That's not the reason. My father has an Agrotron mk2 and he never changed the coolant. The coolant looks good and he bought the tractor in 2010....
