Need Advice on Engine Coolant
Okay so ive noticed that sometimes my balt runs at a higher temperature than normal and it has increasingly become more frequent. I changed the oil probably two weeks ago and thats good checked the level tonight. However, noticed that my coolant level is below the fill line when its cold. Now my question is i read in the book that after 30,000 miles that coolant may need to be added too and i am currently around 32,000 so that makes since. But should i flush the entire system or can i just add some coolant when its cold to the fill line and follow the instructions for adding coolant in the handbook?
get back to me much appreciated
thanks in advice
