I took my '15 FiST out to the mountain roads and did some hard driving.
I was running the Cobb OTS Stage 2 tune (without an IC) but was monitoring charge temps, oil temp and coolant temp with the AP.
Everything was fine until it wasn't. The idiot temp gauge went from dead center to maxed out and I immediately pulled over. Steam was coming out from behind the block.
I let the car cool down for 15-30 minutes and then drove down the mountain. I hadn't made it up that far before the temps jumped and I mostly had it in neutral while cruising down.
At the bottom of the mountain, the CEL came on as the temp again jumped from center to max. The car went into limp mode. I pulled over and had the car towed home.
I took it into the dealership and they told me that it was the hose that connects the reservoir to the back of the block... one of the clamps broke and that's where my problem was. The motor is fine.
The part is H1BZ-8063-C.
The dealership said that this wouldn't be covered under warranty since it's not a mechanical part. It's not that expensive, but what would cause this hose to break? I'm worried that there are bigger problems that the dealer isn't finding. They made it sound like it's just something that happens but in my experience, I've never heard of hoses like that failing for no reason. The car has 41K on it and has been taken care of.
Is there anything else I can ask the dealer to check while they still have the car? I'm going to ask them to do a compression test just to be sure.
