Real owner report, verbatim from NHTSA:
“The contact owns a 2018 Chevrolet Silverado 1500. The contact stated that while driving approximately 40 MPH, the low oil warning light illuminated. The vehicle was taken to Pepboys, and the contact was informed that the engine was a quart and a half low on engine oil. The mechanic determined that a gasket was deteriorating, and the seal had fractured, causing the oil leak. The vehicle was taken to the dealer, and the contact was informed that the engine and transmission needed to be removed to replace the gasket. The vehicle was not repaired. The manufacturer was informed of the failure and confirmed the repair was not covered under warranty. The manufacturer opened a case for the failure. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 84,000.”
Worth knowing: overheating is often the thermostat, water pump, or a hose, not the radiator itself. Confirm the source before you approve a radiator job.

Overheating on this vehicle is often the thermostat or water pump. Describe what it’s doing and we’ll narrow it down.
How your cooling system works
The radiator is one piece of a loop. Knowing where it sits and what it works with is how you tell a real diagnosis from an upsell.
Found a puddle? What the color tells you
Bright green
Classic coolant leak. Find the source before it overheats.
Orange / pink
What most modern vehicles use (OAT). Same urgency as green.
Rusty brown
Old, corroded coolant. Overdue for a flush.
Milky / oily
Coolant mixing with oil. Can mean a head gasket. Serious.
What goes into a radiator replacement
The bill splits into three pieces: the radiator itself, the labor to swap it, and one to two gallons of fresh coolant with a fill-and-bleed to clear air pockets. On most vehicles the radiator sits behind the bumper cover, grille, condenser, and fans, so a tech spends two to four hours getting it out and back in. That access time, not the part price, is usually why two quotes for the same job look so different.
The 2018 Chevrolet Silverado 1500 shipped more than one engine, and the larger one runs a little higher on both parts and access, which is why the estimate moves when you pick your engine above. National-average sites flatten that into a single number. Ask your shop to confirm the exact part for your engine before the work starts.
Estimate note: the per-engine figures are a close approximation from the make and job, refined as real local quotes come in. Treat them as a ballpark, not a guaranteed quote. The only exact number is one from a shop that has seen your car.

A 2018 Chevrolet Silverado 1500 radiator replacement typically runs $520 to $1,290 at an independent shop, parts and labor included.

No. Overheating on this vehicle is often the thermostat, water pump, a hose, or a coolant leak rather than the radiator itself. Confirm the source with a real diagnosis before you approve a radiator job, so you are not paying to replace a part that was fine.Are there recalls on the 2018 Chevrolet Silverado 1500?
