Question

while performing a vcu you determine that the engine coolant is low. what should you do? (select all that apply) 1) mark the cooling system red on the vcu 2) mark the cooling system yellow on the vcu 3) investigate the possibility of a coolant system leak 4) drain the engine oil to determine if there is coolant in the oil

Explanation:

• When engine coolant is low, it is not a major critical (red) issue but a concern (yellow). So marking yellow (2) is correct.
• A low coolant level often indicates a possible leak, so investigating for a leak (3) is a proper step.
• Draining engine oil (4) is not the immediate step for low coolant. Marking red (1) is incorrect as it's not a severe enough issue for red.

Answer:

1. Mark the cooling system yellow on the VCU, 3) Investigate the possibility of a coolant system leak
