2022 Hyundai Tucson
2022 Tucson coolant capacity is 10.11 US qt of ethylene glycol mix for an aluminum radiator. The level check is between MIN and MAX on a cool engine.
Difficulty, time, and cost are estimates when this guide gives them. Torque is a cited figure, or it is left off.

Phosphate-based ethylene glycol coolant mixed as the table shows
A low reservoir is topped up with distilled, deionized, or soft water. The change itself is assigned to a Hyundai dealer.
| Item | Figure | Where it comes from |
|---|---|---|
| Coolant capacity | 10.11 US qt (9.57 L). Mixture of antifreeze and water, ethylene glycol base coolant for an aluminum radiator. | Recommended lubricants and capacities |
| Mixture, when mixing | 35% antifreeze at 5 F (-15 C), 40% at -13 F (-25 C), 50% at -31 F (-35 C), and 60% at -49 F (-45 C). Do not use more than 60% or less than 35% antifreeze. | Recommended coolant, mixture percentage |
| Reservoir level | Between the MAX and MIN marks on the side of the coolant reservoir when the engine is cool. | Checking the coolant level |
The lubricants table lists coolant as 10.11 US qt (9.57 L), a mixture of antifreeze and water, ethylene glycol base for an aluminum radiator. The engine has aluminum parts and the text calls for a phosphate-based ethylene glycol coolant.
The level should be between MAX and MIN. If it is low, add enough distilled, deionized, or soft water to reach MAX, and do not overfill. If you add coolant often, the manual says to have a dealer inspect the system.
The changing-coolant paragraph says to have the coolant changed by an authorized Hyundai dealer according to the maintenance schedule. It does not print a drain procedure.
If the cap is removed after the engine has cooled, wrap it in a thick towel, turn it slowly to the first stop, step back while pressure releases, then press down and continue turning. The mixture table is the mixing guide. The low-reservoir top-up in the check section is distilled, deionized, or soft water, not a second capacity.
