Radiator Corrosion

[drinkmorejava]

Anyone else seeing this corrosion on their radiator? Other side looks completely clean. It's definitely a slow leak, but not something I want my 6mo vehicle to have.

That isn't good. WARRANTY. Do not attempt to fix yourself - lest it cause grief with IA warranty.

Was some aggressive fluid spilled over that? That doesn't look normal. And that doesn't look like normal aluminium corrosion. That looks more as if it had contact with battery fluid or brake fluid.

Spoke to my service department. They weren't terribly happy, but it does seem small at the moment. In lieu of spending an entire day to have it inspected, I've cleaned it all off and we'll see what happens next. Will definitely update once I'm stranded with a cracked engine block

I've seen chemicals used under the hood from carwashes such as pre-cleaners or engine cleaners which can cause etching or corrosion on bare aluminum parts. Not sure that is the case here but there does appear to be a couple of streaks on the side of the radiator where a pinkish like fluid has dried, overspray from a carwash? Coolant on the Grenny is the green HT-12/LC-18 type so something else has sat there and dried out causing the corrosion. It doesn't look to be an active leak which suggests something has gotten in there sat and dried out with the heat.

1. Have your coolant levels decreased?
2. Get it pressure tested by a radiator wallah..

Looks external, like contact with something air borne. Definitely not radiator fluid, have a crawl around underneath and check all metal surfaces, mine was covered in something similar, starter, alternator etc, IA are aware of it, it was noted by my dealer
