P3075 on Chevrolet
Engine Coolant Pump Low Current Performance
P3075 on Chevrolet vehicles indicates engine coolant pump low current performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Traverse. General Motors powertrain code. On engines with an electrically driven or electrically assisted coolant pump, the ECM monitors the current the pump draws as a proxy for how much coolant it is actually moving. P3075 sets when engine coolant pump current falls outside its calibrated range for more than about three seconds — the pump is drawing too little current, which means it is not moving the expected volume of coolant. GM describes the resulting condition as engine coolant flow too low; the pump is often working correctly and the real problem is that it has nothing solid to pump, because the system has lost coolant or has air in it. Typical repair costs on Chevrolet range from $200 to $600, depending on the specific model and root cause.
Common Causes of P3075
- •Low coolant level from an external leak
- •Air trapped in the cooling system after a coolant service or a leak, letting the pump cavitate
- •Leaking plastic coolant control valve / integrated water pump assembly or its housing — a known failure point on GM 1.2L/1.3L/2.7L engines
- •Leaking radiator hose connection, thermostat housing or radiator
- •Electrical fault in the coolant pump circuit — wiring, connector or failed pump motor
- •Stuck coolant control valve or restricted coolant passage
- •Faulty ECM (rare)
P3075 on Chevrolet by Model
Chevrolet Traverse(1 issue)
- Radiator Inlet Hose Quick-Connect Coolant Leak on the 2.5L Turbo LK0 — Overheating and Limp Mode2024-2026
The third-generation Traverse's 2.5L turbocharged four-cylinder LK0 uses plastic quick-connect fittings at the radiator hoses instead of conventional clamps. Owners report the connector at the upper radiator inlet hose weeping and then losing coolant well inside the warranty period — a class action filed in 2026 covering 2024-2026 Traverse, 2024-2026 Acadia and 2025-2026 Enclave with the LK0 alleges the fittings fail prematurely and let the engine run without adequate coolant. Documented consequences run from a low-coolant lamp and a P3075 code through reduced power/limp mode to overheating damage. GM has since extended special warranty coverage on the radiator inlet hose quick connect. This is a third-generation-only issue and shares nothing with the V6 water pump leaks of earlier Traverses.

What does P3075 mean on Chevrolet?▼
P3075 stands for "Engine Coolant Pump Low Current Performance." General Motors powertrain code.

P3075 sets when engine coolant pump current falls outside its calibrated range for more than about three seconds — the pump is drawing too little current, which means it is not moving the expected volume of coolant. GM describes the resulting condition as engine coolant flow too low; the pump is often working correctly and the real problem is that it has nothing solid to pump, because the system has lost coolant or has air in it. On Chevrolet specifically, this code is documented across 1 model.
