Is your Mitsubishi dashboard displaying a coolant symbol? Learn how to fix the problem by checking the fluid level of your coolant and adding coolant if the reservoir is low. This guide provides procedures for checking and adding coolant to a Mitsubishi.
Your Mitsubishi may be low on coolant if:
- Engine overheats
- The engine coolant light comes on.
- Low coolant level error message on dashboard
If the Mitsubishi is overheating or the temperature light comes on, there is a high chance that the engine coolant level is low.
Pullover, turn off the engine, allow the engine to cool down, and check the engine coolant level. See the instructions below.
What you need
- 50/50 Mixed Long Life Blue Engine Coolant
- Allow the engine to cool down.
- Open the hood by pulling the hood release under the dashboard.
- Locate the overflow tank and look at the side of it to determine the current coolant level. It should be between MIN and MAX marks. The overflow tank for the radiator should be just behind the radiator or the passenger side of the engine.
- If the level is below the MIN mark, open the cap and add pre-mixed engine coolant.
- Look on the side of the overflow tank again to re-check the coolant level. Ideally, the level should be in the middle.
- Start the engine and ensure the engine does not overheat and the coolant level does not drop.
If the engine coolant reserve tank needs coolant after you refill it, you may need to add coolant to the radiator. Wait for the engine to cool down, then remove the radiator cap and coolant directly to the radiator.
Do not drive if your Mitsbusihi continues to overheat or lose coolant. Continuing to drive with an overheated engine can lead to permanent engine damage.
What type/color is Mitsubishi coolant
Mitsubishi recommends using the OEM coolant, the Mitsubishi Motors Super Long Life Coolant Premium. The coolant color for Mitsubishi is BLUE. Using an aftermarket coolant needs to be an ethylene glycol-based non-silicate, non-amine, non-nitrate, and non-borate coolant with long-life hybrid organic acid technology. Do not use alcohol or methanol antifreeze.
The coolant must be mixed with 50% water and 50% antifreeze.
