Ford - Mustang :: 2003 - Loud Clicking Noise Under The Hood
Dec 27, 2013
My 2003 Mustang convertible (6cyl) has recently started making a loud clicking noise under the hood that seems to come on after driving in stop-and-go traffic or when turning on the a/c. I don't notice it when driving on the highway at a relatively steady speed. The clicking will continue for a minute or so and then stop for a while. I had also noticed a strange melting plastic or chemical smell coming from under the hood whenever clicking has happened. I had also noticed a couple weeks ago that at stop lights, the a/c was blowing warm air even when on the coldest setting. The air would then become cold again after driving for about a minute. What could this problem (or problems) be and can I fix it (or them) myself?

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.

My son has a 03 mustang GT. He called and said it was making a loud clicking sound. I investigated and it appeared to have a exhaust leak, but I couldn't feel where it was coming from. I started tearing down until I got to the plugs. One of them blew out if the head. I was shocked. Have you heard of this in a car? I'd heard the Ford trucks had problems with the plugs blowing out. Its fixed and running like a champ now.

So this is a two-part question because that's the type of day that I'm having. 1st, I went out to start my car to find that it won't. The radio and lights come on, but it won't actually start, and makes a rapid, loud, clicking noise. I have a video of this however...
My boyfriend thought perhaps I need a jump start, so we were going to try that first but when we went to pull the latch inside the car to open the hood, we found that it doesn't work. So now we can't get the hood open.
So, I'd like to first know how I can get my hood open easily, and what may be going on with it not starting.

First off I have a 1997 F-150 4.6 with 205,000 miles on it.. stock engine and tranny. It's been a great truck and never given me any major problems. But recently something under the hood (wish i could be more specific) makes a really loud HUMMING noise (almost sound like a trumpet). For example- say im driving on the highway and i let off the gas, this humming noise will appear and it is very loud, but right when i give the engine some gas the humming goes away.
Or also when I am driving through town, when i come to a stop light, let off the gas to apply the breaks, this humming noise will come about. what i have to do is stick the truck in neutral and give it a big rev (which i do like hearing my exhaust so it isn't always annoying) and then it stops. note though, it doesnt happen every single time i let off the gas, however it is pretty frequent.
do yall think this is in the air intake system? thatd be my only guess because when i rev the engine it quits, but one thing is it sounds like it comes more from the passenger side of the truck, and it seems to occur more often when the temperature outside is cold. im completely stumped by this one, ive never heard anything like it.

My 99 F150 4x4, 5.4 triton all of a sudden got very loud and has a loss of power. To me, it sounds like a cylinder is straight open to the atmosphere. I at first thought a spark plug blew out or an injector somehow came dislodged but I checked and everything seems ok. It's coming from the passenger side somewhere but is so loud under the hood I can't tell exactly where.
I took the valve cover off to see if a valve is stuck open or something, but I don't really know what I'm looking at as far as internal engine goes. I turned the crank by hand with a ratchet and the valves seem to follow the cams, but I've never inspected valves before so don't really know what to look for. What could be causing this loss of power and incredibly loud noise?

I have a 98 mustang V6 that has developed a clicking problem. When I use the accelerator it will make a clicking noise. It is only there when I use the accelerator and u if I press down harder the noise is drowned out. I put the car in nuetral and also applied the gas to see if it depended on me moving or not and I still heard the clicking but it was a lot faster. It comes from under the hood area but I don't know where (as specific as I can get).

My son was driving my 2002 Explorer, 4.0L, 200K+, yesterday, and it started making a clicking noise under the hood. It clicks in time with the engine running, but it doesn't sound internal to me. It's more like it's in some of the apparatus on top of the engine, fuel delivery system. It doesn't sound like a timing chain to me, but I could be wrong. Maybe I'm just trying to be optimistic, but the thing runs fine, and all of the gauges are normal. I'm going to drive it today to see for myself. Any other part besides the timing chain?

I have a 2006 v6 ford mustang and just developed this problem yesterday.
When I drive the car, the temp guage stay right in the middle, but when I park I get white smoke come from under the hood. I popped the hood and saw coolant leaking from where the top radiator hose meets the engine block. This was producing the smoke. When I checked the hoses, the top hose was hot and hard, the bottom hose was cool and soft.
Extra info:1. I did not touch the radiator to see if there were cool or warm spots2. The overflow bottle looked empty or close to it, but the engine was still hot from driving to work
Thinking this could be one of the following:
1. bad thermostat
2. clogged radiator
3. Air bubble somewhere blocking the coolant flow

Everything might be a slight exaggeration. But fuse 14 covers Backup lamp and day time running lights relay coil, A/C Pressure Switch, Redundant Speed Control, Heated PCV (5.4L), Trailer Tow back-up lamps, ABS, Reverse park aid, EC Mirror.
This is a 2006. 4.6L V8, SCREW. I don't have reverse park aid. When the fuse blows there is a loud screeching noise from under the hood. Can't identify it because the fuse wont go while I am sitting idling in the driveway. The parking break i9ndicator comes on, the ABS indicator comes on, Cruise control goes away and the A/C quits cooling but still blows. I assume EC Mirror means Electronic Compass Mirror. So I need to figure out where the short is.

My Explorer overheated yesterday. Found a very loud hissing sound coming out from under the hood. Let it cool off filled it with antifreeze, started it up, started hissing again. Found the thermostat had broken. Replaced the thermostat. Filled it up again. After replacing the thermostat I found out the hissing sound was coming from the plastic thermostat housing. Replaced the housing. Again I refilled it with antifreeze.
Started to let it warm up and noticed liquid dripping out of the exhaust pipe. Checked it out. Had a green color to it. Then I noticed the coolant resivor was full up to the cap. I did not fill it up past the full line on the side of the resistor. Tried removing the cap.
Found out it had a ton of pressure under it. Bled off the pressure. Refilled it again. Did not put the cap back on. Tried starting it. Instantaneous geyser. Runs like it is missing on 1cylinder. No oil in the coolant that I can see. No coolant in the oil. Could this problem be caused by a blown head gasket of a crack in 1 of the heads or in the block?

For the first 10 or 15 minutes after starting the truck I hear a clicking noise under the hood about 1 or 2 clicks per second. It's kind of a mechanical sound, maybe like a pump working. Could this be the Webasto heater working?

I was heading back into town the other day after fueling I accelerated to pass a vehicle then a pop not as loud as a boot blow off followed by smoke entering the cab and under the hood. After going into neutral and keeping the engine on to maintain brake power I came to a rest in a safe area. I was reading online some people rebuild these but I'm a bit hesitant given the tight tolerances of this part and currently leaning towards replacing the cartridge they sell at riff raff (500 plus new hardware) instead of the whole turbo (850). Now it's time to start cleaning the engine/undercarriage after the 255 mile tow home.

I have a 2004 Ford F250 Turbo Diesel, egr delete, headstuds, intake, dual stacks, etc and when i turn my wheel a loud whining noise comes from under the hood, I noticed it put tension in my brakes. When I accelerate it gets louder and when i let off the gas it goes away... i checked my fluid in my steering pump and it was low so i put some more in and the next day it was all sitting under neath the truck.... any quick fix or do i need to replace the whole pump?

My truck has this rapid machine gun type start, but not always. It always starts though. I had the alternator tested at O'Reilly auto. They said it was good. I have also been trying to see if there is a possible relation with my clicking sound. I guess it might be more of a steady tapping. I thought it was possibly a lifter. My neighbor that works at one of the quickie lubes said he would take a look. He listened with a screw driver and said he did not here the clicking/tapping sound from the engine.
I showed him how when you accelerate on the gas it gets faster and louder. He said it sounded like it was coming from one of the pulleys. There is no kind of squeaking though, just a loud obnoxious tapping noise. He said that he thought it could be a bearing.I am just trying to think if there is still some kind of alternator relation, because also at times going down the road I notice that the lights on my dash flicker a bit. From looking at all of the pulleys, they all look pretty steady. Although, the crankshaft pulley on the bottom does look like it has just a little wobble. We did not have a long enough screwdriver to listen for the tapping in the pulleys. Also, the serpentine belt is good on it.

I have a 1995 Rodeo with a clicking noise, probably coming from the ABS pump by the battery under the hood.
If I pull the ABS fuse, will this solve the problem? I realize I wouldn't have ABS then, but that is acceptable.

I have a 2006 Dodge Durango! I have noticed a clicking/knocking noise when I am driving coming from under the hood. The noise used to diminish somewhat the longer that I drove. Now the noise is getting louder and doesn't seem to lessen as my drive time increases. What this could be?

This is probably a dumb question but what is going on here:
YouTube.....
This is with the AC running. That wheel spin and loud click (it's a lot louder in person) is starting to annoying me. When I am sitting in traffic or at lights and I have the AC running the noise is very noticible in the cab. If the AC is off the idle settles down and the click goes away. So what causes this - AC compressor going out? It needs lube? Freon?

The sound emanates approximately from the area of the coolant storage tank (driver's side, behind the front bumper), though I doubt the tank or its pump is the problem. It sounds only when the car is in 'ready' status. I also think it is not one of the relays in the nearby fusebox. There water-pump drive belt is not on that side, so I don't think it's the water pump or its idler pulley. I have posted a ten-second sound recording on YouTube, greatly amplified. (Ignore the video portion.)

2.7L V6 here. It's got a loud ticking noise under the hood that sounds like it is coming from about the middle of the head closest to the front. It's been doing this for a long time now and is finally bugging me. The noise is related to RPMs meaning that as you rev the motor it gets faster (but not really louder). When I pulled the valve cover about a year ago both heads had lots of gunked up old burned oil which I cleaned up as much as possible. It doesn't throw any codes and runs just fine.
I'm about 99.9% sure I've got a collapsed lash adjuster(s). Is there a way to test it without pulling it? Can I pull the valve cover and have someone turn the engine over a few times to check for oil pumping from the lash adjusters? Is there a way to press it and see if it moves without pulling the cams? Any options to try and clean them while still in the motor?
