Real owner report, verbatim from NHTSA:
“The contact owns a 2018 Buick Enclave. The contact stated that while driving at various speeds, the vehicle shut off and failed to restart. The vehicle was towed to the dealer, where the alternator was replaced 4 times before the dealer diagnosed that the failure was due to oil leaking onto the alternator and the battery. The contact stated that the alternator had been replaced 6 times in total. Additionally, the contact stated while pulling out of the parking lot and onto the road, the vehicle shut off. The messages "Electronic Control Module Failure", "Battery Saver Active", "Battery Charging System" and "Steering Assist Is Reduced- Drive with Care" were displayed. The vehicle failed to restart and was towed to the dealer, where it was diagnosed with the Electronic Control Module (ECM) and alternator failures. The vehicle was being repaired. The manufacturer was notified of the failure. The failure mileage was approximately 72,000.”
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.
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.
Frequently asked questions
How much does a 2018 Buick Enclave radiator replacement cost?
A 2018 Buick Enclave radiator replacement typically runs $520 to $1,150 at an independent shop, parts and labor included. The spread comes mostly from engine and access: the part is $150 to $600, labor is two to four hours, and fresh coolant with a bleed adds $25 to $60.Why does the price change with the engine?
The 2018 Buick Enclave came with more than one engine, and the larger one usually means more coolant, tighter access, and a pricier radiator, so the job costs a little more. Sites that show one national number ignore this. Pick your engine on the estimate above for a closer figure.Is it always the radiator when my Buick overheats?
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.
