Many different vehicles can be repaired, but they may require any or all of the following to get them working:
- Engine Parts/Main Rotary Parts - (6 inventory slots each)
- Fuel Tank Parts - For broken or leaking fuel tank. (4 inventory slots)
- Up to four wheels (6 inventory slots each)
- Scrap Metal - For hull/bodywork repairs. (3 inventory slots)
- Windscreen Glass (optional) - It provides no performance increase but may protect you from bullets. (2 inventory slots)
- Jerry Can with Gasoline - (3 inventory slots)
 First find a vehicle that can be repaired
A good way to see if a vehicle can be repaired, is to see if you can enter it. Repairable vehicle can be entered, even when damaged.
Vehicles that can be repaired, as of 1.7.0:
 Determine what parts are needed
- A visual inspection may give some idea of what parts are required (missing wheels and broken windows are obvious).
- Enter the vehicle itself to determine what other parts are required: the icons in the top left will show red to indicate problems.
- Damaged fuel tanks will leak fuel.
 Collect the parts
Once you have determined what parts are required you will need to collect them. Industrial buildings are the best places to find Vehicle Components and Jerry Cans (fuel containers). If you are repairing a car you need a Toolbox as of 18.104.22.168.
 Replace the parts
Using the action menu on the vehicle will allow you to replace parts. The color of the menu entry indicates the damage of the part. Yellow means more than 50% damaged, red means more than 90% damaged. Two things to note about the menu entries: if you damage the vehicle yourself (e.g. breaking a wheel by crashing a car into a tree stump) the entry may not be correctly colored in the menu. For wheels you can visually inspect the vehicle to determine which one requires replacing, even when the context menu does not tell you. Red entries in the menu may also indicate parts that do not exist on that vehicle, for instance center left and center right wheels on a four wheel vehicle.
A word of warning: repairing a vehicle will alert zombies up to 50m away. Attempting to repair a vehicle while prone and under the vehicle will cause your character to sit up, forcing a collision with the vehicle. This breaks bones, causes bleeding, and knocks the player unconscious. Worse, upon regaining consciousness, the player will automatically sit up again, resulting in more of the same. The only way to escape the cycle of undercarriage-headbutting is to log into a different server where there is not a vehicle above you.
Once the vehicle is repaired, you may need to top up the fuel tank:
- Find a Jerry Can. These are empty when you find them, but can be refilled at the large tanks in most gas stations.
- To refuel the car, have the Jerry Can in your inventory (not backpack), stand near the car and use the context menu. Refueling the car plays an action animation, freezing you in place for about five seconds.
- To refill the Jerry Can, have the it in your inventory (not backpack), stand near one of the large cylindrical tanks at a gas station (NOT the pumps), and use the context menu. Refilling the Jerry Can is instantaneous, plays a sound but no action animation, so you may freely return to your vehicle immediately.
Vehicles count as persistent storage, however only on the server they were created on. If the car is destroyed, everything placed inside will be lost. To save the contents use the context menu while looking at the vehicle and choose "Save <vehicle>", where vehicle will be the type of vehicle. Note: As of Update 22.214.171.124, you no longer need to Save a vehicle. The vehicle and all it's contents on the inside are automatically saved every time the server resets. This also applies to tents.
