Q: Why is my car cutting off? I accidentally placed windshield in the coolant reservoir

To resolve the contamination of the cooling system, that system should be drained and refilled. However, the contamination does not account for the stalling and that will have to be separately diagnosed and the necessary repairs made. Fuel supply faults are a possible cause of stalling as are vacuum leaks and faults with engine sensors. However, there are many additional causes of stalling that might have to be considered depending on how the diagnostic unfolds. YourMechanic offers a stalling diagnostic.
