I own a hatchback ford fiesta.
I took my car out for a drive today for 10 minutes and when I came back, I opened the hood and checked that the water in the water container was quite hot (not scorching, but able to put your finger in without getting burnt) even though it is winter.
I also noticed that the water was kind of brownish-reddish and also the lining just under the cap had this brownish-reddish kind of substance. it seemed like mud, but wasn't thick.
The car was last serviced a couple months ago, and the mechanic told me he drained the oil. I'm not sure about the water container though.
Does anybody have any idea why it is this colour? I was told (and saw online) that the issue may be that the radiator is 'dirty' and is the cause as to why this is happening.
Your assistance will be greatly appreciated.
