I drove about 5 miles today and right when I stopped at home (luckily), my car started steaming and coolant had pooled on my driveway. A decent amount had leaked, but I still have plenty in the reservoir.
It was spraying all over the engine at one point as it is wet all over the place.
I tried turning the car back on about 30 minutes later and now I see some bubbles coming from the top of the radiator (refer to picture below), but it isn't steaming anymore or anything. Perhaps because it isn't hot enough yet?
I can't see a crack and Im not sure how I would find it without taking everything out. Can I pour in some type of radiator sealant like K-Seal and call it fixed or should I try something else? This car has about 160k miles on it (which I know is not the end of its life), but I don't want to spend a lot of money if something else will do the trick.
Also, this may have nothing to do with it, but on my way to work this morning it seemed like the heat never got warm. I only work 5 miles away from home, so it is possible it just didnt get to that point yet, but normally by mile 4 it is warm. - Just thought I would mention that.
