Went to get in my car the other day and the coolant warning light came on, I checked the oil filler cap and there was some mayo type sludge, not a lot but some.
Should I be worried!? I have topped the coolant up and done about 20 miles since and it hasn't moved, the weather here has been absolutely freezing, so could the mayo just be due to condensation aka I am being paranoid???
I am hoping so anyway, some of the sludge is still there, the dipstick is fine with nice fresh oil and there is no oil in the water. Thoughts would be greatly appreciated!!!
