Do they HAVE to be grade 8? Reference thread. http://www.svtperformance.com/forums/showthread.php?905479-Reusing-intercooler-bolts

Pulled my blower to fix a leak in the cooling system...for the 3rd time. Went to screw the intercooler back to the blower with NEW Ford bolts and they snapped. My rented torque wrench must be WAY off because I had it set at 18 inch/lbs. It never clicked to warn me. Having trouble finding...

First time I've ever heard of this happening. It has a Heli-Coil Save-A-Thread on it, which is why I'm trying to remove it so I can install a Time-Sert. But it's too far down into the head to get the socket on it to remove. I'm assuming I somehow managed to smack the Heli-Coil insert down...

Car has had a slight misfire for months now. Changed driver side plugs and the front two plug on the passenger side. I'm paranoid of touching any plugs on the passenger side because I've blown 3 spark plugs over the years. Anyway, misfire was still there after changing 6 of the 8 plugs. I...

I have a very slight misfire and I'm thinking it may be related to bad coil on plugs. Before dropping a few hundred on new ones, and they may not even fix the problem, it would be great if someone had an extra set I could borrow to test out. I live in West Chester PA and would be willing to...

UPDATE: It was the alternator causing the battery light to come on. More updates found below in post #11. TL;DR Car has 192,922 miles on it. Car randomly doesn't start, been going on for months, tried new battery and new battery clamps, didn't help Did a test and found out the...

I get a very slight hesitation when I accelerate in 1st gear. It's only 1st because if I am above 1300 rpms or so there is no hesitation. If I rev the car at a stop (to about 1500 for example) and then accelerate it is fine, NO hesitation. So after the initial acceleration in 1st, going...

My right blinker only works if my steering wheel is tilted all the way up. As soon as I tilt it down, the indicator in my dash blinks fast BUT the rear blinker doesn't light up at all. After some research, seems to be a common problem in Ford trucks. So I need to get to the wires in the...

Off of silver (Paint Code: YN) Mustang GT. I bought it 2 months ago but ended up not needing it. Now it's just taking up space in my garage. Paint is ok. Not perfect. So assume you'll have to get it repainted. $125. No shipping as the thing is heavy. I'm in West Chester PA. I'm...

Need new 3.55 gears installed on my 03 Cobra. I know there is Evolution Performance in Aston...I'm waiting to hear back from them. Anywhere/anyone else that can do it? I already have the gears and install kit, I just need the labor. I'm in West Chester PA for reference. Thanks!

Looking to get gears put in. I know there is Evolution Performance in Aston...I'm waiting to hear back from them. In the meantime, anyone know of anywhere else in case they can't/won't do it and/or I think their price is too high? Ballpark on price would be nice too. Seems to range...

Noticed I'm leaking coolant. It only appears to leak when the fan kicks on. After doing some research, I'm thinking the water pump is leaking from the weep hole. I was looking under the car while it was leaking. There is a tiny gap between the lower crank pulley and the oil pan, it was...

Noticed 2 very dark (jet black) drops on my floor. Looked under the car and at first thought it was coming from the diff cover. But it looks like it is coming from the pinion seal and running down and dripping at the bottom of the diff. In the second pic you can see oil above the...

Had a DDM Tuning HID kit on my car for years but took them out to try LED's. Going back to HID's but I'm doing them with projectors this time. Anyway, I had to get H1 bulbs to fit the projectors, got them off Amazon. But for the life of me I can't figure out how to hook everything back up...

. $175 shipped This came out of my 2003 Cobra. I bought it used form someone years ago. The person I bought it from lied to me. He said it was dark charcoal and was from another 03 Cobra. When I got it, it was originally gray but was painted dark charcoal...I knew this because half the...

Sequential Tail Light Problem (SOLVED) Got my car inspected today and failed because my tail lights aren't working properly. I installed a sequential kit many many years ago. Worked fine for years and then started acting weird. I never bother fixing them but today the car wouldn't pass...

Interior lights went out a few weeks ago. Checked the fuse and it was blown. Put a new one in, blew instantly. So I drove around for a few days with no interior lights. Randomly decided to try another fuse. Worked...for a few days then blew again. So I'm guessing a wire is touching...

EDIT: Problem fixed. Info in post #15. Turns out it was a bad connection on the negative side of the battery. See post #15 for more info. Started happening out of nowhere a few weeks ago. Thought it was battery related, although my battery is only 5 months old, tops. Bought one of...

I want to double check and make sure my water pump is working. Every time I check the reservoir I don't see it circulating. But I've been keeping an eye on temps with my Predator. Nothing out of the ordinary. Any way to kick the pump on like you can with the supercharger IC pump?

Exhaust Leak? Something Else? [Video] UPDATE in post #16. Noticed last night my car was making a different sound. Kind of sounds like an exhaust leak. Drove it around the block and it is definitely not driving right. Struggles/sputters at lower RPM's...like when moving from a stop. Here is...

Earlier today I discovered I'm leaking oil. I'm getting under the car tomorrow to [hopefully] find the exact source of the leak. But from looking at it, without it in the air, it appears to be leaking from the pan. To get the oil pan out, do I need to drop the k-member or can I get away...

Haven't been on this site in a few months. Still driving my Cobra, every day. I'm just over 164,000 miles as of now. Christmas eve I drove 12 hours to FL to visit family. The Friday before I left I had 2 new tires out on. While they were installing the tires they noticed a tie rod needed to...

Did a search, found info on how to remove pulleys, but not a full How To on replacing the back belt. This thread is the closet I've come. But it doesn't say how to remove the actual belt...unless I'm blind. Anyway, one of my pullies decided to go south on me. See this thread if you're...

[Video + Pics]Blower Problems?? Here is what an Eaton looks like after 151,500+ miles Post #34 - More pics added and the problem was found. It was a bad tensioner pulley on the back belt.
