Volvo - 740 :: 1991 - The Unknown Siren Like Sound At Start Up Randomly
Jun 13, 2011
So, first, I need to tell that my car was just turned away from the only mechanic that is a "volvo mechanic" in the region because he said it grumbled and shook too much and it was too much of a liability.
There is only one thing I am concerned about, because it has been grumbling and shaking since I bought it five years ago and it hasn't gotten worse (so why worry!)
This car is a 1991 Volvo 740 sedan with 250,000 miles, a 4-cylinder gas engine and rear-wheel drive.
I have a siren sound coming from the front end, but only sometimes.
When I first start moving forward, I hear a "whooooooooOOOOOOOOOOOPPPPP!!!!" (sounds like a siren) for about 50-75 feet while I am going about 25-30 MPH. It only happens when I first start rolling forward when I first turn the car on from sitting for a while (3 or more hours). If I come to a stop, I don't hear it. If I park and run in somewhere and come back soon, I don't hear it.
I have been hearing a small "whoosh whoosh whoosh" sound coming from the front end that gets faster the faster I am traveling, and I don't know if that is related.

I own a 2004 Volvo S60 2.5T AWD. I have noticed that usually when I am driving and it starts to rain heavily, there is a loud siren sound coming from the engine area. This sound stays till it doesn't stop to rain. Also, if I don't step on the accelerator, the sound goes away. I have taken it to the dealership a couple of times but haven't been able to replicate the sound.

I have a '99 Volvo V70 XC AWD that is making a high pitched whine that sounds kind of like a siren at times. Usually goes away if I'm driving at high speed on the highway. It's more pronounced during in-town driving on acceleration/deceleration. Turbo?

I recently purchased a 1991 Volvo Turbo 740 with 186,000 miles on it. It runs perfect for a few days and then when parked will not start. Attempt to start 1/2 hour later it starts and runs perfect again. It has done that for several days now. I have driven it to locations approximately 40 miles round trip with frequent stops for a period of time and then start up again. This AM it started up perfect as I moved it from a driveway to part in front of my house on the street. Several hours later I went to start it but it would not start. 1/2 hour later I decided to try one more time before calling the tow truck to take to a mechanics and it started up perfect again. I drove it to the library and bank later and ran perfect after the two stops. This is driving me nuts since I had taken it to a mechanic when it did this Monday and it ran great at the mechanics and he could not determine what was wrong. He told me WHEN it stops again to have it towed in and he could determine at that time when it was not running.

We were driving last weekend in a heavy rain storm when our 2004 XC70 started making a loud siren noise. The noise increased with acceleration. We pulled off the road, turned the car off. When restarted the sound was gone, but then returned again when driving in heavy rain. Any clues as to what is causing this noise and if it needs attention?

My ex drives our kid around Maui in a 1990 740 GLE (non turbo) and it's been stalling at the most inconvenient places and not starting for say, 20-30 minutes (then it seems to run fine, at least for another 15-20min. Our savant mechanic with an inherent drive to sleuth out problems is stumped as to why this intermittent stalling is going on. This seems to be happening when it is warmed up, first did it the after "acting funny" in 4th of July bumper to bumper traffic over in Lahaina, when it got to it's destination, it crapped out in the driveway.
Then, it stalled coming home the next day (fortunately right by beach park), a hot day, so I went out to get here a tow. Got rope on, it starts! Take rope off, realize I killed my battery in my Subie Outback while I was fiddling around with the 740, so she pulls it around to jump the Subaru, and it craps out again. So, we get someone else to jump Subie, I turn around to tow her and we go about a mile, tow rope snaps after crest of hill, but, 740 starts up and makes it back to Pa'ia (about 12 miles from that point).
Next day, mechanic looks at it, starts fine. No problem is reproduced, so hard to diagnose. Tonight, it stalled out again and started right back up a couple times during the day, then really stalled out turning onto the busy Hana Hwy from Baldwin Beach, thought I was going to tow her again, but 20 min later, it starts back up. So, for the second night in a row, I follow her home, but tonight it stalls out when making tight turn uphill to get to her neighborhood. So, I manage to tow her up and over to her place. (Accidentally took off front bumper when hook slipped, but I got it back on). And, of course, it starts right up.
Some background:
-fuel pump relay has been tested and is working.
-a couple weeks ago two of the injectors were replaced (or fixed, not sure) after we thought it was really going south (oil in plug cylinder, power loss).
-spark plugs replaced at same time injector issue was being assessed.
-fuel pump and filter underneath were replaced last year. (could it be other fuel pump inside tank?)
Every time I turn around this thing is stalling!

On first start of the day (engine cold), the transmission emits a siren-like sound similar to a hydraulic pump air-bound or cavitating. Sound disappears after first 1 or 2 miles of driving. Does not repeat during the rest of day when engine is warm. Repeats again at first start each morning. Ford dealer check of no value since mechanic could hear nothing with engine warmed up.

I just wrapped up a full day's worth of tear down/reassembly chasing an oil leak at the turbo pedestal. while I had the turbo out I replaced the pedestal with a non-ebpv pedestal and replaced the outlet with a high flow outlet. I also removed the stock exhaust and replaced it with a 4" Turbo Back from MRPB. Once I got everything put back together I hit the highway to check out the new exhaust.
To my horror I started to hear a high pitched airhorn-like sound while accelerating. It sounds a lot like an old police siren... I'm wondering if this sounds like a turbo or simply a boost leak. I obviously had everything taken apart so a boost leak seems likely (still original boots with 191,000 miles). I've ordered new boots from RiffRaff but wanted to make sure it didn't sound like an exploding turbo and that I could safely drive it until I can fix the old boots.
Take a look (listen) at the video : [URL] ....

I have a 1991 Volvo 240 Base with an Automatic Transmission. Just yesterday, I was hopping onto the highway, when all of a sudden, my car would not go any faster than 40 to 45 MPH. It has been running fine up to that point. I ended up just taking side streets, where it ran fine. I have not taken it on the highway after that.

The wife was stopped at a light in her 2006 S60 and when the light changed and she accelerated the car stalled and died. It would not start and thus I had it flatbedded back to the house. Id been told at the dealer during a service trip ($$$) that the alternator might be going bad as it was making a whirring noise and was given an estimate to replace it, the serperntine, pulley, etc.. of $1300. At the time it wasnt a driveability problem and being a working stiff I didnt have the 1300 to spend so I decided against doing the work. Thus, when the car stalled I figured it would be the alternator causing the problem and draining the battery.
I recharged the battery overnight figuring I could get the car turned on then remove one of the battery terminals to verify faulty alternator. However, car would not turn over, Id only get what sounded like a click from the starter. Fine, I figured, the alt killed the battery so I went and purchased a new one and installed it. Car would still not start and Id still get the click from what I believe is the starter. Tried the old bang the starter with a hammer and still nothing. Checked the connectors to the starter and all seemed ok.
At this point, the dreaded "my wife seized the engine" thought popped in my head. I then tugged a bit on the serpentine and noticed the crank turn slightly so Im pretty sure she didnt seize the engine. (fingers still crossed on that one).

I was driving my 91 Volvo 940 Turbo Wagon yesterday morning when, out of the blue, the warning lights came on and the engine shut down. I was still able to utilize the wipers and radio as I sat there for an hour waiting for a tow, but whenever I attempted to start the engine, I got a few rumbles but the engine would not turn over. All belts seem to be in place. I just had the water pump replaced. I replaced the alternator 2 years ago when I first bought the car and installed a new battery about 1 year ago.
Any thoughts on what could be the root problem here?

1991 940 SE Turbo ... I am trying to figure out why there is no power to the 10 amp fuel pump fuse. Drove the car all day with no issues at all.. The next morning it just wont start. Found it wasn't getting fuel..I have replaced the tank pump thinking a shorted pump would disable the system, I have replaced the in tank Fuel Pump, Nothing. The fuel pump relay, Nothing, and pulled the under car fuel pump and checked it and its fine. I don't get it?? what could it be? I went to the library to get a copy of the wiring diagram, but the Chilton's Mechanic wiring bible was so smudged I could not even read it..

I have a 1995 volvo 850 t5. Basically, the engine is making a clicking sound. Immediately on start up, which continues when i drive. In saying that, I've been only doing 5 minute drives so perhaps its not running long enough to go away.
So today, i started it. Car starts ticking. The ticking is like 3 or 4 seconds apart between clicks, and the idle seems to change slightly each time it clicks.
I checked the oil and it was a little low. So i put 2 litres in, and then i ran the car (idling) to see if it would go away. Just for a few minutes. It did seem to go away, but then i gave it a little rev and it came back.
So in summary, clicks on start, idle and while driving. Idle changes slightly between clicks. And there is a few seconds between clicks.
Just checked it again. If i leave it idling the click stops but as soon as there are more revs, it comes back. And the noise is almost like the click of a switch (like when your kettle finishes boiling and the switch flicks off. Not the best comparison but similar).

1991 740 Wagon 2.3 I4 with turbocharger and an intercooler.
My rear taillamp brake lights do not come on.
Of the 4 red lights on both taillamp cluster, only bottom two red lights stay on when I turn on the head lights. When I step on brake pedal with both headlights on or off, all 4 read lights do not come on.
I only get the middle small red light on. (which probably means the brake light switch on the pedal is fine.) I do have the lamp malfunction warning on when I turn on the headlamp or signal lights on.
I changed the lamp malfunction relay (big red cylinder) but things are the same. Found the bottom right red light had one of its filament broken so replaced the bulb but things are still the same.

My '91 240 races when turned on when motor cold, colder it is the moreso, especially in Park and Neutral till it calms down It's happening under 60 degrees Fahrenheit and big time under 32. Sometimes turning steering wheel sharply will stop this. Is this ECU? Transmission? Belts? There seems too show excess transmission fluid on the dipstick, by the way lately, which may have been that way from accidental overfill and may not be related t this insane racing issue.)

I am acquiring a 1991 Volvo 740 Turbo and am concerned about the need to change the timing belt. The seller does not have record of it being changed since he had the car for two years. He had only put about 10,000 miles on it since he had acquired it. It now has 186,000 miles and runs perfect and basically in good shape for its age. If the belt breaks does it ruin the engine?
