Mostly the point is, to make it "look good". There is arguably some protection for wires and pipes underneath against animals chewing on them, depending on how its implemented. Also, on some models it may aide in airflow and cooling/thermal properties. Especially so if it is sitting around a top-mount intercooler. (On some models like the older VW V6 ...

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 ...

Driving around with tires of different rolling radii will cause the viscous coupling to get hot / overheat and eventually fail... As it will probably happen long enough after the tire fitter did the tire, then he won't have to pay, but you will... This is a known issue, both on Subaru and Volvo car with awd and viscous couplings, however, you have read ...

OK, a month later I figured it out! Here's what finally worked: Delete all duplicate audio devices in the Bluetooth menu Pair the phone using the hands-free system via the steering wheel "off hook" button This seems arbitrary but it solved my problem. See the owner's manual page 5-38 for the exact procedure. If you start pairing using the the radio ...

The cover is not purely cosmetic and serves several purposes, one is to reduce engine noise. You often notice there's foam on the inside and they fit over components such as cams and injectors. A second function is thermal insulation. It prevents heat escaping from components such as the exhaust manifold and propagating to the cooler parts of the engine, ...

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 ...

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 ...

The purpose of the fuse is to limit the current in the wire to prevent it from overheating. That could cause the insulation to melt or even start a fire. The other components in the circuit will (should) also selected to handle the same load. So, for example, the accessory outlet should also be able to handle a 20A load. The bottom line is that nothing in ...

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.) ...

The other function can be to control cooling airflow, so yes, get them to put it back - even if they have to buy one...

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 ...

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 ...

The fuse is for the entire circuit. There may be other things on that circuit, sharing that 20A fuse. Also, the gauge of wires used in a circuit is part of the "safe" current limits (maybe why your 12V outlet has a 10A limit), while the fuse is there more for current "spikes" rather than steady loads. I'd stick to the manufacturer's recommendation of a ...

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 ...

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 ...

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 ...

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....

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 ...

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 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.

From a technical service bulletin regarding the 2014 Subaru's: If you receive a customer concern of a “beep- beep-beep” sound when trying to operate the PRG, a likely cause is an incomplete initialization procedure. Repair Procedure: With the ignition “OFF”, open the PRG manually using a fluid motion (no light flash or beep should occur). ...

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

It sounds to me like you 'windowed the block'. When you lost oil pressure, you were at highway speed, so your engine was spinning decently fast, and every revolution without oil does more damage. I think the light noise was rod knock and lifter tick, the pop was the rod breaking and making a hole in the block, and the cloud was the oil that was left in the ...

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 ...

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.
