Not sure if it's anything... a few months ago I had the water pump replaced. Noticed pink residual around the water pump during an oil change and also noticed the coolant level was low. Dealership replaced the water pump; since it was L Certified, I only paid a $200 deductible.
Today while reading the cracked radiator thread, it spooked me out so I took a few pics of my LX570 while it's been sitting outside for 10 hours now. I swear I topped off the coolant a few weeks ago but today the coolant level is sitting half full. What do you guys/gals make of the pic? Is that dried coolant around the coolant cap and to the right of the reservoir?
