2018 Toyota Camry — old 6V-to-12V conversion has decades of splices

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2018 Toyota Camry is losing coolant with no puddle. That's the branch I'd chase this week. Run the total, not the monthly, before you commit. I'd rather be boring and correct. Heat soak after errands is the other window.

This is usually cheaper to test than to guess. If a shop can't duplicate it on the 2018 Toyota Camry, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. If you share a photo of the worksheet, easier to sanity-check. That's coming from doing this as an owner, not a shop. Video is ugly but it shows the hesitation.

Start with the test that can prove you wrong. Swap the cheap/easy piece first on the 2018 Toyota Camry and see if the fault moves. That's the branch I'd chase this week. If it doesn't change the out-the-door or the repair estimate, it's noise. Not interested in a five-hour wait for a shrug.

Intermittent stuff lies if you only catch it once. A pressure test beats staring at a dry driveway if the 2018 Toyota Camry is losing coolant with no puddle. That's the branch I'd chase this week. On “old 6v-to-12v conversion has decades of splices,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. This is the filter I use when the thread starts repeating itself. Not driving it hard until I know more.
