2011 LR4 no longer overheating after sitting

[NuruvianDOOM]

Hi Everyone!

I have a 2011 LR4 that’s been sitting for quite some time. Previously, it had an overheating issue, cross over pipe was cracked, and I was also told it likely had blown head gaskets. Before discovering the cross over pipe issue, I was told to use sealant (in a blue tin I believe). At the time, this didn’t help and the overheating continued. It’s now been sitting for about two years, and I have recently had to start it and it didn’t overheat. It’s been multiple occasions, running for about 45mins or so each time, and no overheating. Anyone ever experienced or seen such a thing?

Engine temperature sensors are designed to work when submerged in liquid (coolant). If it has no coolant left in it or you have a lot of air in the system, the temp sensors might not be registering an overheated condition.

Thank you. I’ll run a few tests, and report back.
