I know this topic is beaten to hell here and I apologize to those who are sick of seeing it, but new 2016 LR4 owner 50k miles.

Taking car into independent shop this week to do coolant crossover. What else should I have them do while they are in there? I’ve read water pumps, thermostat? I am all ears.

 

I'm not as familiar with the V6, but on my 2013 V8, when I did the crossover I also did the intake seals, water pump, thermostat, hoses, and coolant with OEM parts. Basically anything that came out during the repair or that I could get at while I was in there...

 

Make sure they do front and rear crossovers. Water pump and t-stat makes sense. Also - check idler pulleys and replace if they are at all suspect - they’ll shred your belts when they go (I think there’s a TSB on one of the idler pulleys). Supercharger coupler is another thing that is super easy to change when you have the supercharger off. The spring couplers wear out and start rattling like marbles. If its not addressed, the spring wears a groove into the shaft (there’s a TSB on the couplers/snout). LR replaces the whole snout, but many of us have just replaced the spring coupler with a solid coupler from Eaton as a preventative measure.

 

thanks! That makes sense.
