What's the chevy express coolant capacity?

Your Chevrolet Express has various coolant systems; You didn't mention which particular one You're interested in, so let's just go over the two important ones, oil and antifreeze --- some of which may vary slightly depending on the year of Your vehicle, so takes these numbers with a pinch of caution, given that. When it comes to oil, the trim with the VorteCT4300 V6 takeS4.5 quarts, while the 4800, 5300 and 6000s with the V8 all use an even 6 quarts. It's recommended that You put in a full synthetic, as Chevy does, and go with 5W30 for best performance for the engine. For the radiator, You can put 11 quarts in the Vortec 4300 V6 without the rear heater, and 14 quarts in with it. For the 4800 and 5300 V8s, they'll take 13.4 quarts of radiator coolant without the rear heater and 16.4 quarts with it. Finally, the VorteCT6000 V8 uses 14.8 quarts if You don't have the rear heater and 17.8 quarts if You do.
