    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    So the tech said there was a huge bubble in the system causing this issue. He also noticed the harmonic balancer is on the way out and it's causing a intense vibration. Well we hope that's what's causing it because he's replacing it before I get it back

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    My mechanic said he would do the test so I dropped it off there. Right now my roommate is using the garage or I would have tried it myself. I'll keep you guys posted. I also told him about the miss on startup which he thought was weird because he originally diagnosed that as a bad fuel pump but...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    I replaced the cap to the one with a release valve. I took it out and got on it hard after it warmed up and coolant doesn't spray out but after a short drive the coolant level went down slightly. I've eliminated every possibility besides a head gasket... What can I do to determine if it has a...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    Yeah it definitely takes extra cranks to start, once it does it seems to miss and then levels out and runs fine.. I really hope it's not the head gasket. I have also noticed what appears to be small amounts of gunk in the coolant but the oil is still clean. ill attatch a picture of the stuff...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    Ya I've also tried that when I replaced the hose going to it. My overflow tank is only about 3 months old as stated in a previous comment. http://www.americanmuscle.com/mustang-overflow-tank-9495v8.html I use this reservoir as because my car has an electric fan from a 94-95 5.0... this...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    Will do. Two techs from work said that even tho it pressure tested fine it could still be failing. He explained why but I didn't quite understand

    Ya I might have worded something improperly but I do understand that, how you describe it, is how it works.

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    I tried replacing it with a similar style cap from autozone but that didn't help so I put the other one back on which is probably from autozone too but I don't know because it was on there when I bought the car

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    Ya I have read that but the shop I use determined my head gaskets are fine. Since last posting after I tightened the bolts holding on the thermostat neck, this has eliminated my issue since then. If anything the coolant level has dropped slightly after cooling down which I assume were air...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    Mine also says 16 lbs .. so did the new one I bought. The overflow tank is also new (about 3 months old) and it was working fine a couple weeks ago. I found that the thermostat neck was leaking because the gasket set and the bolts had loosened up. I gave them about a 1/4 turn and now they're...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    I thought that could be the issue so I replaced the cap and the hose with new and I still have the issue. My mechanic specializes in mustangs and more specifically foxs and he said my Intake might be warped at the thermostat inlet, he says they all do this so he belt sands them flat but I...

    What Causes Coolant Not To Suck Back Into The Overflow Tank?

    I tried replacing the hose going to over flow tank as well as the cap for the radiator but still after about 45 mins of driving, the car overheats and i check the overflow tank and it's damn near full. The only thing I can think is that there appears to be a small leak at the thermostat neck...

    Distributor Bolt Fell In Dist Hole

    Yes I just got 4 new tires and had them balanced. Although this did help it narrowed down the vibration to the shifter and under my seat. I don't feel anything in the steering wheel. The aluminum driveshaft did help somewhat also but it doesn't feel smooth as I think it should. I have the dog...

    Distributor Bolt Fell In Dist Hole

    Well I still have a dinky stock throttle body so that's probably choking it as well. I need to figure out other problems first. My car has a bad driveline vibration. I got a aluminum driveshaft thinking it would help but it didn't. I know my motor mounts are junk but what else could it be

    Distributor Bolt Fell In Dist Hole

    Thanks. It was not fun but in the process I got the timing done correctly and found out my throttle sensor wasn't working properly so I'm gonna test it later and it should have a little more get up. the gt40 intake i put on isn't going to do much if anything, until I get a throttle body tho I'm...
