1993 Mazda RX-7 Touring — coolant is old by time but low mileage

TrackDriverCommunity StarterJul 12, 20261993 Mazda RX-7 TouringLas Vegas

1993 Mazda RX-7 Touring, about 22,000 miles. Car only has 32k miles but the coolant is several years old. Would you change it based on age alone? I'm trying to prioritize maintenance that matters rather than replacing everything early. Trying to diagnose before I book a shop.

If it were in my driveway, capture voltage while the 1993 Mazda RX-7 is actually failing — after it restarts you've lost the clue. Save the big job until that test fails. Write the result down so the next test isn't a repeat of the last one. This is me being the wet blanket on purpose.
