It sounds like your alternator has not been tightened enough and the serpentine belt is slipping because of it. Since you have new belts on your engine, this is probably about the only thing which it can be. If you press on the belt with your thumb at the center of the long portion of the belt (between pulleys), you should get no more than about 1/2" inch of ...

The short answer is "yes." The longer answer seems to hinge on the cost. The 30K mile service on my 2004 WRX included the following: Inspect Drive belt(s) [Except camshaft] Inspect Camshaft drive belt Replace Engine oil Replace Engine oil filter Perform Replace engine coolant and inspect cooling system, hoses and connections Recommended Performance ...

Sport mode will "increase pickup" by providing a more instantaneous response to throttle inputs. As akadian mentioned, the car will stay in lower gears as you accelerate, allowing the engine to stay in the optimal rev-range for higher torque output. The computer, by activating sport mode, will also not have to 'think' about what gear you should be in for ...

One of two things I think could be happening here. One of your wheels might have thrown a weight and become unbalanced. Second thing to check is to see if you have any ice buildup on the inside of the rim which would also have caused an imbalance. (Not knowing if you are in a winter climate where you are would figure into the second part of this answer.) ...

While the other two answers were ones that were going through my head while I was waiting for the service truck to arrive, the actual problem was much simpler (although much more expensive to fix) The engineer initially looked in the radiator coolant overflow bottle and saw it was at a sensible level, but after having a quick look at the oil dipstick he ...

Subaru engines very rarely blow up. As someone who has owned many and raced a few, and been a member of various Subaru owner forums, I know of some that had problems, but it was almost never the engine. Early Subarus had clutches that were a bit under-engineered, so typically they would be replaced at 75,000 miles, and you could kill brakes with a ...

Does anyone have a definitive answer as to which option I should choose? I do: you need matching tires. That said, it's your car and you have to make the decision. I'd tend to replace all four. @Paulster2 also makes a good point that you could shave down a new one to match. Let's start by looking at one of the most useful paragraphs from the Tire ...

As long as your timing belt was still attached you should be okay. When turning an engine in reverse, the only things it can damage are the oil pump and possibly the water pump. You'd have to do it QUITE a bit though, four revolutions shouldn't hurt it. The reason it CAN damage the engine is because you're forcing the internal mechanisms to run in the ...

Is your Check Engine Light on? That's a rhetorical question, what I mean to say is that if your ’04 Forester is in good tune, it really should not produce that much carbon monoxide. Also, there are really no long-term health hazzards of non-chronic carbon monoxide exposure, other than death. (It binds with red blood cells in a way that prevents transport ...

If so, how do you measure the effect? tl;dr: by measuring the tension between the unbraced mount points. Today, I installed a Whiteline rear strut bar on my 2004 WRX wagon. The car has 162K miles on the odometer and has always seemed in need of a little more stiffness in the area of the rear seats. There's a large volume back there without any sort of ...

A common problem with the 2.5L engines in the 2.5RS are head gaskets starting to leak around 100,000 miles. This is why Subaru normally warranties the head gaskets until 100,000 miles. It isn't an urgent issue and will not cause any catastrophic failure, but It will leak oil. Unlike other cars that urge you to stop driving immediately when the head gasket ...

It's the EVAP vent solenoid. And I think you mean right rear.

I don't think there's any reason to suspect a head gasket right off the bat like that. The first thing that comes to mind is the electric cooling fans. They are on the car specifically to keep it cool at slow speeds since you don't have natural air flow. Get the car up to temperature, open the hood and wait for the fans to come on. If they come on you ...

Subaru engines have long been touted and praised for their reliability and longevity. The engines that seem to be blowing up all the time are almost certainly driven by enthusiasts trying to race as fast as they can up onramps and push their cars to the limit. ( Perhaps that's where the misconception is, if you're going to push your engine to the limit you ...

The first thing to check is the shifter linkage. If it uses a cable the cable my be frayed on the inside of the casing causing the friction. You may also have some other part of the linkage binding up, but my money is on the cable itself. It doesn't seem likely that it would be an internal transmission problem.

It sounds like to me this is the general noise an engine makes when being "lugged" or run at a low RPM under heavy load ... basically, it makes this noise because there is a big boom in the cylinder and no place for the energy to go. This really is not good for your engine at all. You should try to be a little more gentle on your engine and drive train.

In terms of towing, in reality, all you need is enough torque to get over initial resistance, as rolling resistance is much lower. This is why you get people who can tow a bus, or a jumbo jet, for example, so absolute power isn't the be-all and end-all. As I wrote in my comment, the flat-4 boxer engine is a good one for pulling, as it does give smooth power,...

They likely do hold some liability, since they should have known that an AWD should have matching tire diameters across all tires. They may argue that you hold some responsibility since the Impreza owners manual makes this pretty clear: . You must install four tires that are of the same size, circumference, construction, manufacturer, brand (tread ...

The rules depend on the state, but if you're telling the state you paid less than you did, that's Tax Fraud. In Texas, they don't even let you do this, however. The state maintains what is basically a "Blue Book" database of car prices, and you have to pay tax on whatever they value the car at for a minimum. I'm sure other states have done similar. ...

From my experience with a number of Subarus (my current oldest one being an MY2000 Impreza turbo with PPP and 130,000 miles on the clock) I can state that a strut brace makes an amazing amount of difference to both my usage (definitely enthusiastic) and my wife's (normal commute plus kids to school etc) It stiffened the handling up significantly, makes ...

There's an excellent Subaru parts catalog online. I think this is the drawing you want. I'm not sure what you mean by "front" bolt, though -- isn't one directly above the other?

It depends specifically on what's wrong with the starter. Sometimes you hear a clicking sound when you turn the key but the starter motor gears don't actually turn. This could actually be due to a weak battery, but if you know the battery has a full charge, then it could be the starter gears actually failing to turn. You may hear a whining sound, ...

I only see three options. Modify the hole where the spare tire goes, read cut and weld in a new one if there is room Find a way to mount it outside the trunk, like under the car, doubtful that this could be done. See if you can get the tire un-inflated in the same space, my 1991 Camaro came from the factory with an un-inflated spare, and a can of what ...

A few years ago, I had similar problems on my car after changing the pads. The first thing I did was to make sure all of the mounting hardware was tight (bolts torqued to spec, etc.). Next I looked for obvious problems in the suspension. Finally I took it into my mechanic and had him go over it. In the end, it turned out that there was room for some play ...

Most water pumps are designed with a weep hole.This is a small hole that leaks a small amount of antifreeze just before the water pump fails.Most of the time the leak is just above the crankshaft pulley.When you shut off the car the pressure in the cooling system forces some coolant out this hole and it drips onto the pulley and is transfered to the fanbelt....

They make a head gasket leak detector kit to determine if it's leaking. I would be surprised if you mechanic didn't have one. If he or she doesn't they are not that expensive. Here is an example below See my answer here for more info.

Unless the lenses themselves are badly damaged, I would try to polish them up first. You can buy kits with most of the necessary polishes etc from a lot of detailing supply companies- the one I have experience with is the Meguiar's kit that comes with plastic polish and a polishing "mop" for use in your drill. You'll also need a roll of blue painter's tape ...

The short answer is: none. A grade eight bolt that's broken off in the engine is almost certainly not going to extract in any conventional fashion. There's just too much torque on the threads. If you're going to drill a pilot hole big enough to get a grip on the remainder of the bolt, you're basically going to have to drill with a huge bit. Instead, the ...

Typically the fog is from excessive humidity in the vehicle. The three most common sources I can think of are: A leak that allows rain water to collect in the car. Check to see if the rugs are damp, look in the storage well behind the seat and any place water might collect. Do you also notice a sweet smell when the engine gets warm? If you do it may be a ...

All wheel drive vehicles connect the front and rear axles via a transfer case or differential. While on a wheel lift tow one set is lifted off the ground and not spinning and the trailing wheels are spinning at road speed. This places a big load and resulting wear on the power transfer unit. Coasting allows all four wheel to spin at road speed but with no ...
