LowP0025 — Coolant Leak from the Expansion Tank
Description
What P0025 Means
Code P0025 points to a coolant leak from the expansion tank. The source data notes the tank can crack, which leads to coolant loss. The code falls under the cooling system category and is rated low severity.
The expansion tank is part of the engine cooling system. When it's damaged, the circuit is no longer sealed, which causes a coolant leak and, as a result, a drop in coolant level.
