Also remove and inspected O2 sensors for build up. All sensors appear in good condition. Inspected turbocharger actuator and found actuator binding causing low power condition. Replaced turbocharger. Removal of transmission, both exhaust manifolds, engine oil cooler, and evacuation and recharge was required to replace turbo.

Can a bad fan relay cause an engine to overheat?

However, a bad cooling fan relay isn’t the only culprit for excessively high engine temperatures. Many other issues can cause the engine to run hot or overheat. Rather than uncommonly high engine temps, the driver may notice that the cooling fans have stopped running.

What causes battery drain in Advance Auto Parts?

While you’re under the hood (or at Advance Auto Parts), test the alternator. A failed diode in the alternator creates a closed circuit that drains your battery even when the engine is off.

What does it mean when your battery drains overnight?

Why the Battery Drains Overnight A slow battery drain when everything is off is called a parasitic power loss. This happens when something – a glovebox light, an amplifier, any electrical component – is pulling power from the battery when it shouldn’t.

This includes lights, radio, air conditioning, and more. You may be able to tell when your car battery starts to die if you find it difficult to start, have flickering lights, or a weakening alarm system. Your car battery may begin to drain for 8 reasons:

Why are the cooling fans not working on my car?

1. Engine running hot 2. Cooling fans do not function 3. Cooling fans stay on at all times Average rating from 129,472 customers who received a Vehicle Engine Cooling Inspection. Most modern vehicles use electric cooling fans to help pull air through the radiator so that it can keep the engine cool.

Do you need an electric fan for a 5.0L engine?

Make sure the electric fan covers 70 percent of the radiator core and moves enough airflow for the engine size (a rule of thumb is at least 2,800 cfm for a 5.0L engine). The electric fan would be a cooling solution for vehicles that typically drive at low vehicle speeds with low engine rpm, such as cruising.
