Where to find coolant and refill the radiator
Quick answer
Early Access has a Coolant jug; water also works. Choose one liquid, and drain the radiator before switching between them.

Early Access build 26243889, October 28 community file analysis; not independently playtested.
Fill the right part
- Find the Coolant jug at the starting house, or bring water as the fallback.
- Hold the container and target the radiator rather than the fuel tank.
- Read the liquid panel and transfer into the radiator. If the liquid differs from what is already inside, empty the radiator first.
- Check the fill level before starting the engine.
A tick is not a full tank
The October 28 Early Access file analysis reports that the objective completes at 2 litres. Reported capacities are 6, 12 and 18 litres for Radiator I, II and III. Carry more of the same liquid for later stops. Coolant lasts longer than water in that analysed build.
After overheating
Turn the engine off, let it cool and restore cooling liquid. If the warning changes to a broken engine, repair the engine too. Older Demo advice saying that coolant does not exist predates Early Access.
Windshield wipers are a different task
A radiator fill objective is not a windshield-wiper repair instruction. No verified current wiper-part location or replacement procedure was found in the reviewed material. Use the visible part label and interaction prompt; do not drain the radiator to solve an unrelated wiper issue.
