Engine Overheating & Cooling

A server-authoritative coolant-temp model that raises heat with driving load, throttles power and degrades the engine on overheat, then clears on cooling or a radiator repair.

NON-TESTÉ — the reference Lua is syntax-validated, not run in a live FiveM server. Adapt and test on your own dev server before shipping.

Description

A coolant-temperature model that accumulates heat from driving load, and once it passes the overheat threshold throttles engine power and bleeds engine health while emitting smoke. The heat is cleared either by idling/cooling or by an anim-gated radiator repair, giving long drives a real maintenance stake.

Known Failure Modes & Corrective Prompt

  • Client-side threshold — each client evaluates overheat locally and they disagree on engine state. Evaluate the threshold only on the server.
  • Unloaded repair anim — TaskPlayAnim runs before mini@repair loads, so the radiator-repair gesture never plays.
  • One-sided net event — the cool/sync event is registered on a single side, so the reset never round-trips.

Corrective re-prompt: Move the OVERHEAT_THRESHOLD comparison into the server tick handler, register every net event with RegisterNetEvent + AddEventHandler on both sides, and ensure the while not HasAnimDictLoaded(dict) do Wait(0) end loop precedes TaskPlayAnim in the radiator repair.

Framework Integration

  • ESX: not targeted here, but resolvable via exports["es_extended"]:getSharedObject() if you port the job-gating.
  • QBCore: resolve with exports["qb-core"]:GetCoreObject(); restrict the radiator repair to job.name == "mechanic" and require a "coolant" item.
  • QBox: use exports.qbx_core plus exports.ox_inventory:RemoveItem to consume the coolant on a successful repair.

Profit Potential

$150–$2000/mo on Tebex (expected ~$520). [INFERRED] Priced inside the $50-389 script band against the signal-scraper corpus (median seller $11.85K/mo, n=100); steady realism demand puts it mid-band.

Trend Signal

→ stable — inferred: Overheating sim is steady realism demand; distinct from the existing collision-damage stall script [inferred].

Sales Angle

Position it as the realism layer that turns long highway drives into a maintenance risk, feeding the mechanic economy. Recommended Tebex price $69.
