Hello all, I have an 03 Cobra with 106k miles and am having progressively worse and worse issues. Only started noticing it about a month ago, it wouldn't allow me to shift into 3rd/4th easily. I checked tranny fluid that weekend but was full. Last fluid change was about 8k miles ago with ford...

All stock cooling system besides 170* Thermostat on 100k mile 03 Cobra. I'm trying to figure out how to determine if my high speed fan is on or if it's just my low speed. Low speed is set at 186* and high at 190* but both sounds the same. I turn AC on and it sounds very similar as well. Is there...

I completed a first compression test because of a cooling issue I was having and wasn't pleased with the compression results. For the time being I believe I've solved the cooling issue and do not believe it was in result of the compression #s. Also I haven't found any smoking, stumbling...

Hello SVT, I have a 2003 Cobra that I'm considering widening the stock rear tires/rims out a bit with a 1" spacer. I'm looking at these on eBay as they specifically say they are designed for the factory wheel...

Hi guys, I recently bought a cobra with 3.2 or 3.1 ish upper pulley, JLT CAI, and flowmaster catback. It was all installed for a performance shop here in AZ and tuned with a handheld SCT SF3 by them. My question is as I flip through the settings of my tune that's listed as a "Pulley Tune" none...

I've got a SVT that at least needs a head gasket changed and wanted to check with any decent SVT mechanics to see what they charge before I start digging into it myself.

A few weeks ago after driving for about 75 minutes full AC in about 90 degree weather the engine temp started to rise slowly. Turned off AC and it went back now. I did some work that weekend. I drained coolant from Radiator (not from Engine side as the bolt was stuck on good -- may be my...

Hello all, I've got a few questions pertaining to my new to me 2003 Cobra. First I'm curious to know if anyone can visually ID my modifications completed by previous owner. Specifically the Pulley mods? ** Now the previous owner who openly said he has no idea what the shop installed pointed to...

WTB 03/04 Cobra Chin Spoiler let me know what you have! Thanks

Hi all, in the middle of a coolant flush but want to verify this is the plug I'm to remove for the engine coolant on the drivers side. I'm following http://www.svtperformance.com/forums/showthread.php?435249-03-04-Cobra-Engine-Coolant-Flush-How-To!!! but it is not as described. Picture is...

Hello all I've decided to upgrade from my 32 valve Mustang to a 32 valve Mustang. I was planning on taking back down to the shop the PO had it completed at to tell me exactly what pulley mods are done. Although very happy with it so far, still working out small problems(somewhat of a...

I know about the sequence to disable the chime but of course this only works if it recognizes the seat belt buckling in the first place. I under plugged the connector under the seat but then this kills everything to the seat power and all. I went to Ford dealer today to ask about it and they...

I've yet to look on my car but after quite a bit of online searching I can't find out where this plug is located? I want to burp my system until I can properly flush the system this weekend. Reservoir is full but did not check anything on the Crossover tube. Thanks!

Been searching for a clean stock GT in a few particular colors in my area for a short while, well this 2003 Mach 1 came up that matches what I've been looking for but I'm not sure about the price.... The condition of the car is great. Interior / engine bay is very clean. Exterior has small...
