what oem coolant do i need to fill the tank on the left side up by the head light?

thanks

 

do you mean the acd reservoir (driver's side) or the radiator coolant overflow (passenger's side)?

if it's just radiator coolant you don't need to use oem fluid

if it's the acd you are speaking of: search acd fluid

 

If you're ****... go get some Mitsubishi OEM coolant.

Otherwise distilled water is fine - just remember to flush before winter.

You can go to most auto parts store and buy pre-mixed ready to use 50/50 coolant.
If you buy concentrate you need to mix with distilled water.

 

Passenger side.
