Replace 12V battery on my timetable
Hello,
We have a 2014 ESh and want to keep it a long time.
It has about 172,000 mile but runs perfectly, and an engine oil analysis shows that the engine is in good condition. We frequently take long trips in it, so reliability is important.
I am thinking of changing the 12V battery (it is original, so 11 years old). I am also thinking of chaning the coolant pump.
Does anybody know what these will cost and should I change anything else proactively?

Battery - maybe. But coolant pump? I have not seen a single mentioning of coolant pump failing. Toyota had some issues with belt driven pumps but the electric pumps are bulletproof afaik.
I would only replace TPMS sensors proactively in your situation (if getting new tires). The rest I would just wait till it breaks.

Are you the original owner? Any other preventative maintenance other than oil changes?
I'm a brake fluid every three years, and coolant every five years kinda guy myself. Agree with the battery, and tpms sensors with next set of tires. Belt and hoses maybe, along with PCV. Maybe spark plugs and eCVT fluid?

Changed the plugs, coolants (engine and inverter), transmission fluid, brake fluid. I can change the PVC. Good idea.
The car does not have any belts. Hoses feel OK.
I certainly hope the car wll last another 10 years! It is a Lexus after all!

My goto battery supplier is letting me down these days. Recently my local walmarts all have switched from EP batteries to JCI. You can tell by the SN changes and these all have a built in handle. However some of these batteries have post corrosion on the shelf.
Pricing has not changed but, corrosion on a fresh new battery is insane. Looks like costco might be the better deal these days.

I always research battery manufacturers before I buy any, and found that Duracell auto batteries, sold at Sam's Club, are made by East Penn/DEKA (probably the highest-rated mfg.).Duracell auto batteries, particularly those sold at Sam's Club, are manufactured by East Penn Manufacturing (DEKA).

I would replace the battery, water pump and the coolant with SLLC.
OEM water pump is around 200 dollars, it is an electronic one.
Factory coolant must be replaced after 10 years or 150000 miles, together with the inverter coolant. After that, every 5 years.
Did you replace the spark plugs?
