2024 Toyota Tacoma — coolant is old by age but mileage is low

Intermittent stuff lies if you only catch it once. Two 2024 Toyota Tacomas can feel identical and have different causes, so measure before you copy someone else's repair. Don't erase codes until someone who can help has seen them. On “coolant is old by age but mileage,” that was the fork that mattered for me. Time, temperature, and whether it's in gear are the notes that actually help a shop. I already checked the easy fluid levels.
