Your Chevrolet Express has a variety of coolant systems; If you can specify which one you're interested in, I can provide more details. Let's focus on the two main ones, oil and antifreeze, which may vary slightly based on your vehicle's year. For the oil system, the Vortec 4300 V6 trim requires 4.5 quarts, while the 4800, 5300, and 6000 V8s all need an even 6 quarts. It's recommended to use full synthetic 5W30 oil for optimal engine performance. As for the radiator, the Vortec 4300 V6 can hold 11 quarts without a rear heater and 14 quarts with it. The 4800 and 5300 V8s need 13.4 quarts without a rear heater and 16.4 quarts with it. Lastly, the Vortec 6000 V8 takes 14.8 quarts without a rear heater and 17.8 quarts with it.
The maximum amount of coolant that a Chevy Express can hold is 6 quarts.
