* Green: This is common for older, traditional silicate-based coolants.
* Orange/Red: This is common for more modern, HOAT (Hybrid Organic Acid Technology) coolants.
* Yellow/Gold: Some manufacturers use this color as well, often indicating a different type of HOAT coolant.
You shouldn't rely on color alone to identify the coolant. The best way to know for sure is to:
1. Check your owner's manual: This will specify the recommended coolant type for your vehicle.
2. Check the coolant reservoir: There might be a label on the reservoir itself indicating the type of coolant.
Using the wrong type of coolant can damage your engine. If you're unsure, consult a mechanic or your vehicle's service manual.
