The truck has 230,000 miles and has a squeal that sounds like a belt but it's not. I have put the truck in neutral coasted with the engine off and the noise is still there. The noise only happens when the weather is cold and only when the truck is coasting. Under acceleration the sound goes away.
Toyota Tacoma Prerunner 2003 (2.7)...
I have a 2001 Toyota Tacoma that has a knock or ticking in cold weather. The problem starts sometimes immediately after I start and other times it is only when I press on the gas in the cold mornings after a few min warm up. The noise goes away after 10 min. The question I am wondering is this:
1: could it be worn piston rings and the pistons are slapping the cylinder wall
2: is it an oil pump problem or a oil restriction issue
3: is it a valve guide issue
4: with the history of the 2.7 having exhaust manifold issues (poor manufacturing) could a cracked manifold be the issue
I change the oil myself, the oil filters have been OEM toyota, the noise has been going on since 60,000 miles, the truck is at 230,000 miles.
I own an '05 Prerunner with 56k miles. Had the front pads replaced and turned the rotors last Spring.
Now, after sitting for awhile, as I back up the front brakes squeal. (Sounds like a rock in a caliper its so loud.)
Toyota has a TSB to fix this.
I have a 2003 GMC Envoy with 76000 miles on it. I heard a louder exhaust noise than normal when I start the truck in cold weather. I had it checked and was told that the exhaust system was OK but that the noise was because the motor mounts needed replacing. I have never heard of this before. Before I spend this money I wanted to see what your reply was to this question. Is it common for motor mounts to have to be replaced on this type vehicle with this mileage and age?
View 2 RepliesWhen it is cold out or wet my serpentine belt squeals a lot or a couple of minutes. It had progressively gotten worse this past winter. The shop said the belt looks fine and Toyota wants me to pay for them to look at it...
View 2 Replieshave an 2009 Toyota Corolla 62K miles. If the car sits out 8 hours or more in VERY COLD (zero degrees) weather makes a 1-2 second clashing/sparking noise the split second after turning the ignition on but before engine starts. I tried to attach video/audio. The car starts and runs fine. isn't a ticking or knocking or tapping noise assoc. with bad engine. It isn't squealing noise assoc. w/ serpentine belt. I've been waiting for it to get cold enough to leave overnight at Toyota dealer. I keep wondering if it isn't related to the botched oil changed at the Toyota dealer a couple yrs ago when they forgot the oil & I ran car about 30-60 seconds. At the time, they said all was okay and did compression test (Cyl 1=178psi, #2=175 #3=180 #4=178) all within the normal specs 145-189. I got a 2nd opinion at another Toyota dealer at time who removed valve cover and inspected cam caps and scoped cylinder walls and said all was okay and compression good. No mechanical problems- uses no oil, check engine light not on, etc. What noise is and why just when very cold and car sits out long time?

View 1 RepliesI have a 1996 Toyota Tacoma, 5 speed manual pickup.
Occasionally I use the air conditioner. I'll be driving along and it's working fine but then it stops putting out cold air. I pulled into the mechanic one day and confirmed that when it is not putting out cold air, the compressor still seems to be running.
If I go into a store for about 15 minutes and then come out again, it works again. What might be happening?
After my car has sit for a couple of days, it doesn't like to start. By, " doesn't like to start", I mean it doesn't even click when the key is turned. I put a new battery in it but that didn't work. If I get it to start it seems to always start after coming out of a store (knock on wood). This only seems to be a problem after it has sit for a while.
View 9 RepliesMy wife had the misfortune of the horn sounding each time the signal was turned on. Solved problem by not using signal... However, the horn still went off after the truck had been turned off for an extended period of time (long enough for her to leave and not hear the horn until returning a couple hours later). She was able to stop the horn by placing the vehicle in neutral (manual transmission). I have not been able to reproduce the problem. I thought it may be the "relay integration", but after removing this from the vehicle the signal does not work, but the horn still works. Is there a relay, switch, etc. that controls both of these devices?
View 1 RepliesI bought a remfg denso starter for my 2000 toyota tacoma prerunner 3.4L V6. I spent hours without success trying to get the old starter out. Brought it to a shop and had the new one installed. When I do a cold start, there is a screech at the end when the engine catches that sounds exactly like starting a car that is already running. This happens on cold starts only. Warm starts work fine. Due to the fact that I bought this part separate, having to pay to have a new one installed again is annoying to say the least. I spent another 4 hours today trying to get it out without success. See YouTube link for video of the noise. It's actually the quietest one yet.
View 13 RepliesThis is a great little truck we only use occasionally. It has 145,000 miles and runs great, but the a/c temperature is very sporadic, and this week it is 100 degrees! One day it will work fine, and the next day it will only blow hot air. Sometimes the air starts out cold, but after 5 min of driving, it turns hot. I have had the freon checked and my mechanic said part of the compressor (forget what he called it) was probably getting stuck at times, and he would have to pull it all out and possibly replace...

I've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.
In Jan my 94 Toyota Camry started having issues with starting- for instance, I would run an errand for 10 minutes get back in the car and it wouldn't start. However, this tended to be random. When this problem happened more often I took it in and they said I needed a new starter so I got one (Feb) and didn't have any issues for a month, but then began to have the same issue on and off again. I took my car back in for the second time and they said it must have been a bad starter. They gave me ANOTHER new starter (Apr) and my issues continued soon after. I took it back in and they didn't have an answer for me other than the starter was good. Took it to another mechanic and he had the car for two days and could not find ANY ISSUE with the car. I let it brush over during the summer months because I never had this issue (June-Aug) and now that it's gotten cold again I'm having this problem.
Few things to note: -Anytime I have this issue I'll hit the starter with a hammer and it will ALWAYS start. This has been the case since January.-It ALWAYS starts in the morning and when I get back in my car after working all day. However, if I were to run errands in the morning or at night it would not start with the stop and go. -This only happens in the cold months -They tested the newest starter and they say there's nothing wrong with it.-Within the past two years I've had MANY things replaced on this car and any shops I've taken it to say it's a great car with no issues they can find.
My son and I were coming down the mountain on I-70 near Georgetown, Colorado in a snowstorm in his toyota 4runner. We had just gone through the Eisenhower Tunnel. There was alot of traffic, and driving conditions were terrible. We were traveling approximately 10 miles per hour when my son told me that his brakes were not working. We downshifted, and then slid into the guardrail on the median (we were in the left lane). Luckily we were not hurt, and we did not hit anyone else. Once the car was towed back to Denver, the brakes worked again. My son is getting the car checked by a mechanic, but why the brakes gave out and how he can avoid that happening in the future? Was it related to the cold weather (approximate 10 degrees)? I did not feel that he was riding the brakes as we descended. The road was icy at the time.
View 19 RepliesI have the LED mod and several weeks ago, my LED stopped indicating and the truck would not start in cold weather unless I jumped the terminal on the relay. I replaced the relay and while I was tightening one of the small lugs, the one towards the nose of the truck, I felt it break.
The truck acted just like it had been for the weeks prior, if I didn't jump the relay, it wouldn't cold start, so I assumed, because I had broken that small lug, it wasn't getting the signal to turn them on.
So what now? obviously the GP's themselves are working, as the truck starts when I jump them. But for some reason no signal is getting to the relay. What do I need to check to see what is going on between the PCM and the relay?
I have a 2004 Sienna LE and it has left/right signal problem (not working) in the morning or when the weather is cold. The problem usually last for about 5 to 10 minutes until the inside car temperature becomes warm.
When this problem happens the emergency lights are working. Only the signal left and right do not work.
Is this a common Sienna problems? I brought the car to the dealer but they refused to fix it because they cannot duplicate the problem. I am guessing when the warranty has expired, they will make suggestion to replace the part but not until then.
I replaced my fuel filter on my 2003 2.4L tacoma 2wd. 65k miles. At the same time I checked the valves. No valve adjustment needed. Now I hear 4 to 6 rapid metallic clicks when i start the engine cold. Once it happened when it was warm. This fuel filter is not original equipment.
View 1 RepliesI have a 2001 Toyota Sienna xle that started running rough when the weather turned cold. When started, the car idles very high and will not shift properly until it was been running for around 5 minutes. After that it will run well for about 10-15 minutes and then begin to run rough or poorly. The problem is very noticeable at low speeds and when stopped. It never actually kills, but it feels like it is going to. At high speeds it is less noticeable but occasionally you will feel it jerk or chug like the transmission is slipping or a belt or something.
I took it to a mechanic who checked the codes and found that the ignition coils were supposedly bad. I say supposedly because they replace three of the ignition coils and the problem still persists. I then took it back to the mechanic who then told me it was the oxygen sensor. The o2 sensor was replaced and the problem is still there with no noticeable improvement. I again to it back to the mechanic who tells me that they scratching their heads.
I have done some looking around on the internet and have found some discussions that seem to have some promising leeds and actually last weeks car talk show had a caller who described a similar problem. The guys told him it could be a oxygen sensor but they thought a better possibility would be EGR valve or a vacuum leak. Not sure if this sienna has an EGR, but I plan to suggest looking into it to the mechanic. Also, I found some discussions talking about the idle control valve and the engine control module.
I have a 1999 Toyota Tacoma manual shift and when driving with the air conditioning on my truck makes an odd noise. The noise is very sporatic but seems to happen most at about 50MPH and 70MPH. I am going to try and type out the sound...."Chht" It is quick and only happens once at a time. The power of the engine drops when it happens as though it may cut out. But it is very quick.
