I recently replaced the water pump and front crossover on my 2013 LR4 5.0L. Thought I was good to go for a while until I read a recent post of a blown motor (overheat) due to a failure of the heater manifold. I wasn't aware that the heater manifold was a potential issue otherwise I would have changed when I did the front crossover and the water pump. Now I'm a bit nervous and thinking I should get on this asap. My rig has 87K miles at the moment. Should I be concerned? Also, while I'm in there I was thinking that I would change the 8 o-rings for the intake manifold. That was until I checked the price... $25 each?!!! Now I'm wondering if that is really necessary. These o-rings are original, as I never changed them when I did the front crossover. I would imagine if they weren't sealing properly that I would have noticed by now?
And another thought I had... Is there such a thing as an aftermarket alarm that could be installed that would give an audible alarm if a sudden drop in coolant pressure occurred? Does such a thing exist? Seems like that could potentially save a lot of these 5.0L's that have a crossover failure. Just a thought.
