    Coolant Temps 2008 GT

    Thanks for the info. This may well the case for mine since it’s 12 years old and I have no idea if coolant has ever been serviced. Sent from my iPhone using Tapatalk

    Coolant Temps 2008 GT

    More thanks to everyone...I will perform all of the above procedures and report back. Ordered the 180F Stant thermostat. I’ll use a 60/40 mix of distilled water/coolant and thoroughly pressure wash the stock radiator. My GT is mainly a daily driver and mostly highway so I don’t think I need to...

    Coolant Temps 2008 GT

    Thanks guys. I’m not sure on age of coolant or thermostat so I’m going to change both. Just wondering if those temps are a little high. I’m thinking a month from now when it’s over 100F outside I don’t want to deal with overheating if I can avoid it by detecting a problem now. Sent from my...

    Coolant Temps 2008 GT

    My car is completely stock and I just hooked up my Livewire and started monitoring coolant temps. Yesterday it was 90F ambient with light winds and cruising at 60-75 mph with AC on my coolant was running 220-226F. Seems high to me. Even coasting off the highway to a stop it only came down to...

    Need help

    Where is it listed? Complete kit? How much? I’m looking around at kits now for my 2008 GT. Sent from my iPhone using Tapatalk

    2005 GT driveshaft

    Same here. I installed mine in my garage with car on jack stands. I watched some YouTube videos beforehand just I’d have an idea of the best process. It’s not bad at all. Probably took me an hour give or take once I had it up on the stands. Sent from my iPhone using Tapatalk

    2005 GT driveshaft

    I just put the Ford Racing one piece aluminum on mine. Made a huge difference. My stocker had 150k miles. So much smoother clutch engagement and no clunking. Sent from my iPhone using Tapatalk

    Edelbrock Stage 2 Supercharger install

    Congrats on the job. That’s awesome! I may have missed it but what car is this going on? Just curious about the car. I want a FI mustang real bad. My 2008 runs great stock but has 150k miles and not sure it’s wise to supercharge with high miles. Sent from my iPhone using Tapatalk

    How many miles you got?

    2008 GT manual with 145k miles. All stock. Contemplating a supercharger these days but not sure with the high miles. Runs like a top. Sent from my iPhone using Tapatalk

    Suspension clunk over bumps

    My rear lower control arm bushings have started squeaking. I suspected that was the source of the squeak so I forced some grease in around the bushings and the noise stopped. Mine are done for so I’m going to replace them. Just thought this might help you. Mine have 140k miles on them. Sent...

    2008 GT Bogging Intermittently

    Thanks guys. I’m still troubleshooting this issue. Right now everything is good. I’ve been watching throttle position on my monitor. Is it normal for commanded throttle position to fluctuate like 30% while cruising on flat ground. I had the cruise control set on 70 mph on level ground with no...

    Voltage Drop When Rad Fan Kicks On

    So I pulled the alternator and cleaned all the mounting points. I used my dremel to get all surfaces shiny including the connection for the wire connected to the alternator that goes to the battery. Everything seems ok. I still get a small dip in rpms when the fan kicks on but it’s not nearly...

    Voltage Drop When Rad Fan Kicks On

    I cleaned both battery posts and three grounds in the engine bay. Seems to have helped a little. The surge is about 100 less rpms both ways. I’ve looked around and don’t see any other obvious grounds. Any particular place I should look for more? I think I’ll also get the battery load tested...

    Voltage Drop When Rad Fan Kicks On

    Date on the battery is 4/18 so it appears to only be one year old. It was ran down completely when my first alternator failed. I put it on a slow charger before I reinstalled it after replacing the alternator but I guess it could have been damaged by the faulty alternator? Sent from my iPhone...

    Voltage Drop When Rad Fan Kicks On

    Thanks. I’ll check on the brand but i do know it’s a remanufactured job. I guess I could pull it off and see if the parts store will swap it out. Seems that if I’m not running a big amp or aftermarket lights the 135 amp should be ok if it’s working like it should. Sent from my iPhone using...

    Voltage Drop When Rad Fan Kicks On

    When at idle at approximately 700 rpms and the fan kicks on I get a large voltage drop and rpms dip down to 400 and then surge back to 1000 before leveling back off at 700. Voltage goes from 13v down to 11.5v and then returns to 13v. I replaced the fan hoping it was bad with no change. I...

    2008 GT Bogging Intermittently

    Dang! I’ll have to check that. After about 500 miles since my last issue I noticed a slight hesitation again today. This seems to be a repeatable cycle now. If I reset the KAM or retune it runs good for about 300-500 miles the gradually gets worse again. After about 1000 miles it is down on...

    2008 GT Bogging Intermittently

    I haven’t ordered the delete plates yet and ever since I removed and thoroughly cleaned the TB and reflashed to stock tune the car is running great. It’s been about 300 miles since then and all is well for now. I’d done this previously but I only wiped down the TB the first time. This time I...

    2008 GT Bogging Intermittently

    Drove about 50 miles today and the car ran perfect. It’s been about 100 miles since I cleaned the TB and reinstalled the stock tune with no hiccups. I’m not complaining but wish I knew what was causing this issue. I report back if the issue returns. I drive about 75 miles a day so I’ll know...

    2008 GT Bogging Intermittently

    Well after reading up on the CMCV issues I believe this could be what is causing my difficulties. I’m going to look into deleting these for sure. I’ve got a tuner I just need a custom tune and I’ll order some delete plates. Can’t hurt to at least give this a shot. Edit: I do have the ability...

    2008 GT Bogging Intermittently

    Thanks guys. It’s actually P115E FORD - Throttle Actuator Control Throttle Body Air Flow Trim at Max Limit I’ll read up on CMCV. I’m completely unfamiliar with what these are. I did notice a fairly large amount of oil coating inside the intake manifold when I removed the TB for cleaning. I’m...

    2008 GT Bogging Intermittently

    Another idea I just had...could the computer be pulling timing due to knock (real or false?). One thing I haven’t tried is a tank of premium fuel. Any thoughts on this idea? Could a knock sensor be giving a false reading and the computer compensates? I have no idea if this would be as...

    Thanks. That’s a good thought. These are the type of ideas I was looking for. I’ll check the obvious places. Sent from my iPhone using Tapatalk
