Hi there, at the time of purchasing my CPO LR4 (2015) I also bought an extended warranty from Cornerstone (Xtended Auto) and was curious if anyone here has experience working with them to get a new engine replacement? Sadly, like many others here my mechanic thinks my block or gaskets are likely toast and is recommending an engine replacement after dealing with coolant leaks for the past year. Any guidance or help is greatly appreciated as I imagine the insurance company is going to fight tooth and nail to avoid a $20K+ bill.

This is directly from the insurance document:
