Ford 7.3L Power Stroke (1999-2003) :: Fairly Loud Clicking / Clunking Sound Coming From Front Under The Hood
So my '01 E350 has been fine but tonight when I went to start it I didn't get a WTS light and the SES light was on and there was a weird number on my PHP Hydra that looked like r5 ? This happened a few times back to back so I tried starting it and it just cranked and cranked. Wtf? So I started pushing the button on the chip and all of the sudden I got the WTS light and the hydra flashed, now the chip was on tune 10 instead of 5 where it was when I parked it. I should also note that during these episodes there was a fairly loud clicking/clunking sound coming from the drivers front under the hood when I toggle the key on.. Sounds like maybe a relay? Louder than I recall ever hearing.

I have a 2003 F350 with a 6.0. I just finished replacing my HPOP (Adrenaline Pump from Diesel Site) and fired the truck up and its making a hissing sound from the rear of the motor back by the turbo almost sounds like a tire leaking and its loud enough to hear over the engine. The truck is running and idling good but it doesn't seem to be quite 100% when I step on it.
View 10 RepliesFord - Explorer :: High Pitched Whistling Sound Coming From Under Hood
I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.
View 4 RepliesHonda - Accord :: 1996 - Overheated And Smokes Coming Out Of The Hood
The ECT sensors on my 96 accord was broken. Hence the car overheated and smokes were coming out of the hood. Took the car to a honda dealer, here's what need to be replaced.
Radiator & cap
Lower & upper hose
Clamps
Thermostat
Coolant reservoir
ECT sensors
To do the repair they estimate 7 hrs of labor. I am not mechanically inclined so is this within the ballpark of how long it's going to take to replace the parts listed above. Does the 7 hr estimate seem reasonable?

View 5 RepliesSaturn - Vue :: Loud Hissing Noise Coming From Back End
This morning when I pulled into the garage after taking my daughter to school and shut the car off, I noticed a very loud hissing noise coming from the back end of my car, underneath somewhere. When I came back out an hour later to leave for work, it was still hissing. I drove to work and all was fine, but when I went out to the lot after work my car was completely dead.
I tried jumping it, but it wouldn't even take a charge. I had to find a ride home and will get it towed tomorrow. I'm sure the hissing noise is the cause, but what's going on. My car has never given me any problems--it's run perfectly for almost 150,000 miles (5 speed manual transmission). Maybe this is the end?
Ford - Explorer :: 2003 - Grinding Or Humming Sound Coming From Left Driver Side Front
Alright so I'm having a problem with my 2003 Ford Explorer. I've recently noticed that when I get to above 40 mph, if my steering wheel is straight, I hear a loud kind of grinding or humming sound coming from my left driver side front. If I am going about 65 mph, it gets even louder and if I crank the steering wheel to the left, that's when it really gets noisy but as soon as I crank it to the right, the problems gone. When I do hear the hummin sound, I can feel it in the steering wheel. I have replaced al of the tires and it didn't work. Also, the car slightly pulls me to the right.
View 10 RepliesFord Excursion :: V10 - Engine Knock / Loud Noises Coming From Under The Hood
The wife drove the Excursion (V10) to work today and it ran normal and didn't have any loud noises coming from under the hood. When she started the engine to return home it immediately started knocking. This is not a ping, but a knock. Not a loud heavy knock, but much louder than a ping. It has a fast frequency, seems too fast to be a rod knocking. The frequency is similar to a valve issue, but the knock seems to be too heavy for lifters. Oil looks good. Just changed out 2 weeks ago. Truck is driven everyday.

Just noticed a sound of air sucking sound under the hood on heavy acceleration only, the harder I push the louder it gets. Either sucking or hissing sound. I feel no difference in driving. No loss of power or anything else. Just the sound of air coming out like a leaking air line. I will check later this afternoon if its affecting my turbo boost. I have 235000 klms on the clock

I noticed a hissing sound coming out from under the car. It's more audible closer to the rear of the car as if air is escaping through a hole. Tires are good and not loosing air. When the fans turn on the hissing sound goes away momentarily and comes back. What could this be?
View 13 RepliesCorolla / Matrix 2009-13 :: On Cold Startup Car Makes Loud Hissing Sound Then Runs Normally
It has happened three times now on cold startup my car makes this loud hissing sound then the car runs normally. Once a few months ago. Again a few weeks ago and this morning it was pretty cold maybe low 50's. I normally turn the key in the ignition to the "acc" position let it "ding" once then start the car. What could this loud hissing be that only happens on cold startup then the car runs like nothing happened? I called my local mechanic and he said he wouldn't know if he can't recreate the sound. Which you really can't because it happens once every blue moon but I wanna make sure I'm not ignoring a problem that could get worse.

I have a 2003 Ford F450 super duty xl. At first there was a loud clicking sound coming from under my dash. I charged the battery up and the sound went away but the truck will fire up but not turn over and start. I thought maybe it could be the relays but the clicking sound quit.
View 2 RepliesFord 6.7L Power Stroke Diesel :: Hissing Sound Coming From Engine Mounted Fuel Filter
I changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.

Noticed hissing sound coming from the rear windows when the AC is on... It's very annoying so I always crank up the volume of the music. Funny thing is when you open one of the rear windows slightly and the sound is gone. I thought it was from the roof rack but it's not.......coz the sound is there when the car isn't moving too.....as long as the AC is on.....and the rear windows are closed tight.....
View 4 RepliesFord - Aviator :: 2003 - Hissing Sound Near Rear Of Engine?
I have the '03 Lincoln Aviator 4.6 DOHC. It has a noticeable knock/ping/chatter and somewhat sluggish acceleration. I notice the PCV hose was collapsed and shredded. I replaced the hose and valve, didn't change idle or acceleration and I still hear the hissing noise in the same region. I unplugged the EGR valve and started the truck, the idle was the same as before I unplugged the valve. could a bad EGR valve give a vacuum leak that is hard to detect? I tried testing for leaks by squirting starter fluid near the suspect areas, and I couldn't detect anything.
could a bad PCV valve be caused by a bad EGR valve and/or vise versa?
Santa Fe (DM - 2013+) :: Hissing Sound Coming From Underside Of Vehicle
I have a 2016 SFS 2.0T.
For the past week or so, I've been noticing a hissing sound coming from underneath the car near the front driver side area.
It almost sounds like air being let out of a tire. It only happens when the car is turned on, and the sound is there when the car is in park or in gear.
Not noticing any change when driving the car.
Accent MC (2006-11) :: Hissing Sound Coming From Rear Seat
So I ended up removing my rear seats of my 2010 hatchback gs, but there is now a hissing sound coming from the rear where the seats were. The sound starts as soon as I start the car up until I shut the car off. I'm assuming that this noise has always been there just noticeable because of the seat removal. Is this just the fuel pump?
View 8 RepliesGolf IV / Jetta IV :: 2000 - Hissing Sound Coming From Bottom?
Ever since I bought my 2000 mk4 golf I've had this super loud hissing noise coming from the bottom of the car. Almost like someone is spraying compressed air when your foot is on the throttle. Sound gets louder the more you depress the pedal. Had a catalytic converter code so after a few months I bought a new cat, welded it on, and the sound fairly went away. Still present, now months later the sound is now a bit louder but It's gotten on my last nerve, I want to fix it but I can't seem to figure out what that noise is.
Almost sounds like my car is a classic beetle by the way it accelerate at times. The car is sort of sluggish than normal at times, no codes, no lights, sometimes peeling out in 1st gear the car hesitates like I have regular power, then I have this sudden burst of 1 second power then back to normal until I shift then I never feel it again until I'm back in 1st and WOT it. Car does smell like gas a little sometimes, not too prevalent but nonetheless noticeable especially going in reverse. My gas meter seemed to fluctuate at times, I may have a bad pump maybe, not sure if that has anything to do with it.
