LR4 HSE coolant weird question

[jackkyxu]

2010 LR4 HSE

spent all the time in NE part, just temporarily moved to SE part

for the latest 3 months before reaching the SE, never had the coolant low message

this morning, I noticed the coolant low message, but ONLY once

I checked the coolant expansion tank when cold this afternoon, the tank is almost empty

the car just did a 600 miles trip, no message, no overheat, the water temperature seems in the right range all the way

any idea?

Thanks

if it is a leak, it should be quick to observe it even after it is topped off, right?


it is going for another 400 mile trip, and I am going to top it off before the trip

and keep checking the coolant level reguarly

It's not a recall. Technical Service Bulletins are normally. on your dime after the factory warranty is up.

I read through the TSB, abut it seems there is no solution provided there

any one you can think of?

Thanks

You may need a new coolant pump. See this other bulletin: https://app.box.com/s/lye2qwchuyx6w9hwbhuk91r31owwte3e

finished the 400 mile trip yesterday afternoon

the evening before yesterday, I put in 1 qt 50/50 mixed coolant into the tank to bring the coolant level up to about 0.5 inch above the upper range mark on the side the tank, then I used the car for a while,

parked overnight, yesterday morning before the trip, I checked the level, it is right on the upper range mark

I checked the coolant level this morning, the coolant level remains the same as staying on the upper range mark

will this help to pinpoint any issue?

Thanks
