Where is the thermostat located on a 1990 Chevy Astro?

The thermostat on a 1990 Chevy Astro is located on the engine, at the bottom of the engine's water pump housing. It's not easily accessible and requires removing some parts to get to it. You'll likely need to consult a repair manual specific to your 1990 Astro (with the correct engine size – 4.3L V6 is the most common) for precise instructions and diagrams.
