so i’ve got this coolant leak and i have been filling up with just water for the past couple months until i can get it looked at. only problem is it’s getting down to freezing at night now and i don’t want to crack my block. if i buy the coolant concentrate and add it in, will it just mix up with the water that’s already in the system? or will it cause problems. there’s still some water in the reservoir as well, so i am hoping adding the concentrate will be enough to keep from freezing? it’s a 2.0t if that helps :)
yeah sure. try to keep it the same type of coolant. make sure it meets or exceeds vehicle standards. follow manufacturer dilution procedures.
