3.6 TDV8 bad overheating on hills towing caravan

Does the compacted graphite iron block metallurgy conflict with the alloy radiator, and cause blockages?

I'll pass on the suggestion. I suspect that my brother would also like to know just how badly it was blocked.

He doesn't have a high volume pump to reverse flush it but I have a 8HP 2" 600 L/min water transfer pump so if he removes the top tank but leaves the blockages intact then I'd like to reverse flush it to see if the blockages can be cleared.

I’m glad I have a spare radiator & intercooler.

Yes the results of a flush would be interesting. Ta.

i was more thinking cutt off the sides and have a look.

The radiator has top to bottom flow and has plastic tanks so the crimps can be peeled back.

I expect not as LR has been using this combination at least since the introduction of the TDV6.

is the top to bottom flow a lack of space thing?
