Out of interest, has anyone here had a coolant leak firstly from the oil cooler, repaired, and then shortly after a coolant leak from the thermostat?

I have an ongoing case with Land Rover as my argument is they are the same piece of work/claim, but Land Rover of the view everything was done right the first time and therefore the second repair is entirely seperate

Hi. I had a mysterious coolant leak.
Couldn't locate it anywhere. Then saw on YouTube the plastic thermostat housing was a weakness. It drips onto the manifold and evaporates so hard to detect. Also oil in my coolant. After fears of a head gasket I saw again on YouTube that it was more like oil cooler. Had the oil cooler replaced and at the same time the leak on the thermostat housing was discovered. Both fixed at the same time but were separate issues I'm afraid.
