Real owner report, verbatim from NHTSA:
“The contact owns a 2018 Honda Odyssey. The contact stated that while stopped at a stop light and attempting to make a left turn on an exit, there was a knocking sound coming from the engine. The contact called 911 and the Fire Department; however, there was no fire. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and it was determined that the engine and starter needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 23V751000 (ENGINE AND ENGINE COOLING); however, the VIN was not included in the recall. The manufacturer was notified of the failure and confirmed that the VIN was not included in the recall. The failure mileage was 167,000.”
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 Honda Odyssey radiator replacement cost?
A 2018 Honda Odyssey 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 Honda Odyssey 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 Honda 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.Are there recalls on the 2018 Honda Odyssey?
Yes, NHTSA lists 16 recalls for the 2018 Honda Odyssey. Recall repairs are done free of charge at a franchised dealer for that brand, so it is worth checking your VIN before paying a shop for related work.
