Build 12922607 (released December 10, 2023) is a maintenance update for My Summer Car
that primarily focused on internal file changes and bug fixes without official public patch notes. Despite the lack of new features in this specific build, modern guides (updated through 2025 and 2026) emphasize several critical mechanical changes introduced around this period. Essential Startup Steps
Battery Management: Immediately place the old battery from the garage on the charger. If it fails to charge, you must buy a new one from Teimo's shop for roughly 500mk.
Triggering Uncle's Van: Bolt the driver’s seat into the Satsuma using 9mm bolts. This activates a timer (approximately 90 real-time minutes) after which your uncle's van will spawn.
Initial Shop Run: Use the tractor or boat to visit Teimo’s. Priority items include:
Mechanical: 1 Alternator belt, 1 oil filter, 1 box of spark plugs, motor oil, coolant, and 3 bottles of brake/clutch fluid.
Survival: At least 8 packs of sausages and several cases of beer.
Catalog Orders: Order the Ratchet Set from the magazine immediately. It is essential for efficient assembly, as using individual spanners is significantly slower. Satsuma Assembly Reference Part Group Important Notes Crankshaft 9mm Spanner Secure with 6 bolts. Pistons 7mm Spanner
Ensure you check for blackened pistons; these are worn and need replacement. Cam Gear 10mm Spanner
Critical: Align the arrow on the gear with the arrow on the engine block to prevent an engine explosion. Head Gasket
High coolant temperatures cause rapid wear; a failing gasket leaks smoke. Electrics 8mm Spanner
Danger: Always disconnect the battery before installing the alternator or starter to avoid death by electrocution. Recent Mechanical Changes

. This build introduced significant changes to the early-game economy and vehicle maintenance, specifically targeting the Ruscko and the Hayosiko (the blue van). Essential Early-Game Checklist The Van (Hayosiko) Delay
: You can no longer get the blue van immediately. Uncle Kesseli now requires time to lose his license. You must wait a few in-game days and periodically check his house for the keys. The Ruscko Gamble
: To officially own the Ruscko and get its keys, you must now win it in a high-stakes game of
(blackjack) against the Pigman. You have to risk 4,050 MK or even your house and Satsuma to win the deed. The Moped (Jonnez ES)
: This remains your most reliable early transport. Ensure you lean the bike over to fuel it and keep a 2-stroke fuel mix ready. Building the Satsuma
The Satsuma AMP is a 1.0L inline four-cylinder vehicle. To ensure a successful first start in this build: Wiring Mess
: Ensure the battery is grounded correctly to the starter motor and engine block to avoid electrical fires. Fluid Management
: Check that all bolts on the brake and clutch master cylinders are tightened (size 7mm and 8mm) to prevent leaks.
: If the car cranks but won't start, verify there is gasoline in the tank and that the fuel pump is bolted securely. Major December 2023 Mechanics
: Your house now has a fuse box. If the lights go out, you must buy replacement fuses from Teimo’s Shop. Kilju Selling
: The drunk man (Jokke) still buys Kilju, but the price varies based on the sugar/yeast balance. Selling him "juice" or bad Kilju will result in him attacking your house later. Towing Service
: If you lose your vehicle, you can call the tow truck (Fleetari) to recover it, though it is expensive. For detailed parts locations and bolt sizes, the Satsuma Build Guide on the official My Summer Car Wiki

Before you go full rally mode, you’ve got to play by the rules. To pass the car inspection , keep these essentials in mind: Standard Tires Only:
Don’t bother showing up with those stock wheels; the tires are trashed from the start. You'll need Gommer Gobra road tires from Fleetari’s Repair Shop Keep the Springs Stock:
Those long coil springs might look cool, but they are an automatic fail at the inspection office. Tighten Everything:
It sounds obvious, but forgetting one bolt on the brake linings or wheels is a one-way ticket to a permadeath screen. Performance Upgrades: Beyond the Basics
Once you’ve got your inspection sticker, it’s time to actually make the car fast. The Cooling Crisis:
The stock radiator is notoriously bad. Your first major investment should be the Racing Radiator to keep that engine from melting during a grocery run. Tuning for the Rally: If you’re eyeing the weekly amateur rally, the Rally Build guide recommends a 3.700 Gear Ratio Air/Fuel Mixture (AFR) gauge to dial in your performance. Safety First:
A roll cage and racing harness aren't just for show—they’ll actually save your life during those inevitable high-speed encounters with a ditch. Pro Tips for the Perplexed The Ratchet Set:
Save yourself hours of clicking. Order the ratchet set from the catalog via snail mail early on to make assembly significantly faster. Manual Labor: If you're struggling with the engine's finer points, the Satsuma manual mod Nexus Mods
is a lifesaver for understanding exactly where that one pesky bolt goes. The Hard Truth: My Summer Car Build 12922607 for My Summer Car was released
is designed to make you suffer. If you aren't throwing beer bottles at your project car in frustration, are you even playing?

Are you planning to build the Satsuma for the rally , or are you aiming for a perfect factory restoration this time? My Summer Car update for 10 December 2023 - SteamDB
For My Summer Car build 12922607 (released December 10, 2023), there are no official patch notes detailing specific new features [10]. This build consists primarily of internal file changes across various game depots rather than a documented list of additions or "draft features" [10].
In the context of the community and tools like MSC Editor, "drafting" or planning a build typically involves these standard features and community-recommended workflows: Core "Build" Features & Tools
MSC Editor (Satsuma Report): The most common way to "draft" or fix a build is using MSC Editor, which includes a "Satsuma Report" tool [7, 11]. It allows you to:
Check Bolt Tightness: Instantly see which bolts are loose or missing [7, 9].
Instant Install: Technically "draft" a build by setting all parts to installed status and then using the editor to tighten all bolts at once [7].
Condition Repair: Reset the wear and tear on engine components like the head gasket or alternator belt to ensure a "perfect" build [7].
Save Backup Managers: Using tools like MSC Save Backup Manager allows you to draft different build paths (e.g., rally vs. street) and quickly swap between them without losing progress [8]. Essential Build Checklist (Build 12922607+)
If you are manually drafting your build plan for the current version, the general sequence remains consistent with recent updates:
Engine Block Assembly: Crankshaft (9mm), Pistons (7mm), and Head Gasket [1, 4, 9].
Cylinder & Timing: Cylinder Head (7mm), Camshaft (5mm), and Timing Chain alignment [4, 9].
Support Systems: Water Pump (7mm), Alternator (7mm & 10mm), and Starter (7mm) [4, 9].
Chassis Mounting: The Subframe (10mm) should be installed before lowering the engine into the bay [1, 4].
Suspension & Steering: Steering Rack (9mm), Struts (9mm bottom, 10mm top), and half-shafts (14mm) [1, 4, 9].
For those looking to bypass the manual grind, you can find pre-built save games on Nexus Mods that feature "rally-ready" or "fully restored" Satsumas, essentially providing a finished draft of the car [7, 8].
