W203 coolant advice.

[amazighman]

Hi.

I need to do my thermostat change on my W203 C220 CDI, I have got quite a bit of red antifreeze which meets MB 325.3 , I know that most people say to Use G48 thats MB 325.0.

Anyone knows if I can use the 325.3 red coolant , Looked through the owners manual which didn't mention the coolant spec....

No, you require the 325.0

Use a pump or baster to remove the coolant from the expansion tank. You will get out around 2L.
when you change the thermostat you will loose very little coolant.
Use G48 so you have no mixing issues.
