Re: Project Lex
Had our spring opener meet this Sunday. *Was a little cold out, very slight occasional mist but not bad overall. *Got a couple nice shots of the car:
Then leaving the meet, in 2nd I gave it a little too much and got a little sideways and hit the damn curb. *Feel like an idiot. *Drag radials, cold weather, slight mist, and me still getting used to the power it has = dumb mistake. *So my wheel is hurt and i popped a tire. *Also the fans had shut off for whatever reason so while we let it sit and idle coolant started coming out of the overflow. *That's when we realised the fans didn't turn on. *Shut off the car, the BTI gauge showed 219* when I finally looked at it. *So... *Now gotta figure out what to do about wheels, and going to investigate the coolant issue, hoping I didn't pop the head gasket. *I've post-poned my dyno appt so I can take my time and make sure everything is OK before I stap her on. *Sucks, but could be worse. *Doing my best to get back on the horse here and fix it and keep moving forward. *I figure it could be worse, it's not like it caught fire the day before trying for 6's at TX2K right? *I'll be fine, and I'll get it fixed, not so bad really.

Re: Project Lex
Ouch, that sucks, but could always be worse.
Doubt head gasket issues at 219f, but worth investigating.

Re: Project Lex
Yeah I wanna be sure the car is 100% before the dyno, so just playing it cautious right now. Gunna spend the next few days slowly going over it to make sure everything is ok.
So if anyone knows a local place that can repair curb damaged wheels, please let me know!

Re: Project Lex
219F is nothing for coolant temps so I don't see anything to worry about there. Are you running straight water or a mix of water/coolant/Water Wetter?
The wheel definitely appears repairable, wish I had a suggestion for you on where to take it that isn't in Texas!

Re: Project Lex
Well I left a voicemail with Alloy Wheel Repair in Shoreview. I also called and spoke to a guy at Twin City Wheel in White Bear. So we will see what these folks have to say once they see the photos. Hoping they can be repaired. If not, then I guess I gotta start thinking about what to do with wheels.
Yes I agree that temp seems like it shouldn't be a big deal. But at the same time, coolant was coming out of the overflow. So why would coolant be coming out of the overflow. Not just like a few drops, like a decent amount came bubbling out. So that's why I'm a little concerned there. Why would it do that? Is 220-ish hot enough for coolant to come out? Or maybe I cracked the radiator, system lost pressure, and caused coolant to start coming out places. Not sure yet, have to look into that.

Re: Project Lex
220 is definitely not hot enough to cause a problem with the engine. A stock C7 will run 230+ just cruising down the highway. My first guess is you boiled the water which is why it overflowed. Do you have anti-freeze mixed with the water to raise the boiling point? How old is your radiator cap, and does it hold sufficient pressure in the system?

Re: Project Lex
It's a water, anti-freeze mix. I can't say the exact mix, but probably around 60% water if I were to guess. Yeah it probably boiled, so that's what I'm trying to figure out. I'm assuming that somehow the system lost pressure, and the pressurized system is what makes it not boil. So if it was hot enough to boil at normal atmospheric pressure, then maybe i say cracked the bottom of the radiator, and so then the coolant did start to boil because it wasn't pressurized, not because it was "too hot" per-se.

Re: Project Lex
60/40 mix is perfectly fine, C7 and GTR both come with that ratio from the factory. Do you think you banged the radiator on the curb too? Unless you see a leak from the radiator area as well, my first assumption would be a worn out radiator cap.

Re: Project Lex
It's an old rad cap, but it happened as a result of banging the curb. There were zero issues with the cooling system until about 2-3 minutes after hitting curb.

Re: Project Lex
How long do you suspect that cooling fan has been non-functional? Are there any signs of leaks now that things have cooled off? If the impact in some way damaged the radiator fan, and that allowed temps to creep up, that may have been just enough to expose the cap's weakness. If you cracked the radiator, there would be a puddle under the car (besides the one underneath the overflow tank).
As far as you can tell, did anything else make contact with the curb besides the wheel/tire?

Re: Project Lex
I suspect everything, including fans, were fine up until I hit the curb. Here's my best play by play run-down.
- Started the car to let it warm up, it sat and idled for probably 15 minutes while I helped clean up and say bye.
- Got in car to leave. At this point I didn't look at any gauges or anything, but I assume the coolant was up to operating temp of ~180*. Nothing looked, sounded, smelled out of place, I fully suspect everything was just fine. Pulled out of parking lot.
- 20sec later I hit the curb.
- 20sec later I was back parked, left the car on/idling, we all were looking at the wheels.
- after maybe 2-3 minutes of us looking and the car parked idling (hard to say i wasn't timing it), someone noticed some coolant under the car. So we shut the car off immediately.
- popped the hood, noticed coolant coming out of overflow.
- After maybe 30sec of "WTF is going on", I went and turned the car key to the ON position (without starting the car) assuming the fans would kick on. We noticed the fans didn't turn on. Thought about that for 10 seconds and then checked my BTI gauge to see if we were over the setting where the fans turn on. That's when I saw 219* on the gauge. Didn't look at my stock gauge to see if i was even near red, didn't even think about it, but wish I would have. But anyway at that point we determined something is probably wrong with the fans and turned the key back off.
- Let the coolant bubble out for maybe another minute before it stopped.
So since the car sat and idled for like 15-20 minutes before I drove off, I highly predict everything was just fine. Plus I drove it a half hour there with zero issues. It wasn't until directly after hitting the curb did the coolant thing occur at all. So has to be related. Still don't know what though.
The coolant reservoir is molded into these fans, so it's pretty much directly above the radiator. So any puddle caused from overflow is right where a puddle would be from cracked radiator. Really hard to say right now.
As for did anything else make contact. It doesn't look like it other than the under side of my front lip. I looked under there briefly with a flash light and didn't see anything sticking out like a sore thumb. I'll have to look closer though. The lower crossmember that the radiator rests on seems like something that definitely could have hit. This is a OEM radiator so plastic end tanks could have cracked. Lots of things to consider, just need to get under there and start figuring it out, and keep my fingers crossed I didn't hurt the motor.

Nobody was harmed during the filming of this stunt, other than my ego I suppose haha. You know what it was, I setup that dyno appt at DB, so just being associated with anything mustang related means this was already predetermined by a higher power to happen simply because of that, out of my control!

Re: Project Lex
What position wheel is that? I assume the front so that you still can replace the control arms and hopefully not have any bent suspension parts?

Re: Project Lex
Passenger side, front and rear wheels. Front one is worse, and is the 2nd picture. First pic is of the rear. I looked under there briefly, didn't notice anything bad, but something I'll be looking at for sure as I get to looking closer. Good news is I have all new front arms that I'll be installing none-the-less lol.
Good news is local place in White Bear said they can repair the wheels. $100/ea to repair (not including coating). Typically 1 day turn around. So I'll be getting those over to them in the next day or two. Seemed like a fair price and an excellent turn around time.

Re: Project Lex
But you'd want to match the paint though, and that's another $150, right?

Re: Project Lex
Match what paint? You mean my plastidip on the wheels? Lol no I will worry about finishing later.

Re: Project Lex
Alignment had to get redone anyway when I put these new front arms on, so no real biggie there. This is exactly why I have cheap fun cars, doesn't hurt so bad when I break it haha.
