Thread: Another TDV6 Crankshaft Bearing Failure

The engine oil cooler is supplied by coolant from the heads before exiting to the radiator.
If the coolant temp exceeds 100 degC could this overheat the oil causing an issue.

To remove the radiator on the SDV6 requires decanting the ac system removing the condenser, intercooler, radiator and fuel sub-cooler in one assy
then disassembly from there!!!

Lol. But, a Disco is only (!) 400 kg heavier than a Territory, and I see lot's of the big Fords towing. Things like horse floats and big boats.

Mysterious.

So, what is normal oil temperature on an SDV6 engine?

I see ~110C when looking at such things on my IID tool. Corresponding coolant temp is around ~85C.

Radiator gets air from Grill, Intercooler from the mouth in the bumper..

Ah I see now. I was throw off by the intercooler being twice the thickness as the radiator. Looks like I will need a new intercooler rather than radiator due to mud ingress. Radiator is untouched and intercooler had been hammered. I had some thick mud clogging up the entire front end from a hole while doing the Karunji Track. 6 water crossing the next day cleared that out though.

I thought motor oil temperature over 130C was extreme (back in my boy racer days)

5W-30 oil is 30 weight oil @ 100C ?

The oil temp sender unit is in the sump I read...

Your previous post stated Coolant temp...

100c is not a magic number - it only sticks in people’s heads as “boiling point of water at sea level”...

Most if not all vehicles run above this under hard load.

Coolant temp leaving the engine is different to radiator temp - especially on the outlet side of the unit.
