The decision to replace is largely based on the thickness. The repair manual should tell you the minimum thickness, below which you should replace the rotors when doing the repair. Use a pair of calipers and measure the rotor thickness, if you're below this number you need to replace the rotors. You may also wish to replace the rotors if you have ...

There are three cases that cause brake rotors to need to be resurfaced/turned and/or replaced. Gouging of the rotor by the brake pad holding mechanism (the pad were rubbed completely away and the metal holding the pad start digging into the rotor) Warping of the rotor from extreme use (rotor gets too hot and warps upon cooling) The rotor itself wears down ...

Wow, I'm in the minority here. It is my firm belief that you should have your rotors turned with every brake pad/shoe replacement! If you do not do this everything will work perfectly fine, until you apply the brakes then if your brake rotors/drums were glazed, heavily scored or worn out of parallel to the new brake pad your will stopping distance WILL be ...

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 ...

If it runs out of fluid it will need to be replaced, because it will destroy itself rapidly (probably preceded by a loud grinding noise). In the meantime, as long as there is sufficient gear oil to wet the gears it will be fine. As for severity, it is common for differentials to develop a "seep" around the front seal where the drive-shaft connects, or the ...

No, it does not need to be done every time. Don't believe the hype. If you have warping, then you should re-surface, provided you have not worn beyond the minimum dimensions for your discs.

As Bob says, formal servicing should always follow the manufacturer's schedule - Make sure to take into account any variations suggested for your location/climate/usage pattern. This should include routine things like oil and filter changes, as well as more major, but less frequent things such as timing belts. In terms of more general checks and ...

At least in the United States you are not required to use the dealer for service,parts or repairs to maintain your warranty. You will be required to have the warranty work done at the dealer except in extenuating circumstances,(like the nearest dealer is 150 miles away) but you must still contact them first. If they deny a warranty claim on the basis of non ...

Overheated rotors can show some tell-tale signs. Once the metal has been overheated, it can weaken or warp which are both bad things. Some signs: Bluing Cracks These "spider cracks", "heat cracks", or "heat checks" are only on the surface of the rotor, but are still bad.

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, ...

A simple test that you can perform in your own driveway is: For each corner of the car, push down hard several times (the car should be bouncing visibly up and down) When pushed down, release and watch The car should bounce upwards (above the normal resting point) and then immediately settle at the resting point. Additional bouncing indicates worn or ...

Let's see if I understand your situation correctly: All of your tires have well over 40000 miles on them. I've never sold a car with brand new tires on it so I'd suspect that those tires are quite old indeed. One of your tires is a Douglas Xtra Trac. It's telling that tire-rack.com doesn't even list this brand for me to refer to its rated mileage. So, ...

The Mercedes M103 engine in your 300CE is a proven design, old enough to demonstrate its longevity—lots of them are running around still with 300,000+ miles on them. The head gaskets are pretty much the only serious weak point. If the engine was not burning excessive oil (more than a quart every 5,000 miles) or showing other signs of extreme wear before ...

The salvage yard will use an interchange manual. At one time it was a large series of books but is now a computer program. Each major and some not so major component of a vehicle was given a number. The number is then cataloged and all vehicles that use the same part are listed. When I have doubts I'll check several on line sources of parts. If one source ...

This is what Vauxhall has to say about the front fog lights. Firstly, we need to remove the inner paneling (basically the bumper): Release left and right front wheel cut-out panel Unscrew 4x nuts (1) Pull out wheel cut-out panel slightly and fix in place Undo front panelling at top Unscrew 3x bolt (2) Release left and right wing protective ...

Radiators are pretty simple to replace. If you've never done it before, look at some youtube videos, and set aside about 4 hours for it (90 minutes, if you're handy with a spanner). Repairs on radiators are rarely successful - it's often a plastic sidewall that goes on Subarus. Sticking various concoctions in the radiator (or a raw egg) just causes extra - ...

Beyond what jmort253 said, and separated out into a specific answer at Bob Cross' suggestion: I ran into a particular difficult to track down problem which was caused by the clutch in the starter opening up. The starter would wind up and make a screeching sound, but sometimes wouldn't turn the engine over. I was thinking it might be a broken tooth on the ...

The "fun" part is going to be getting the original bushing out - you might have to cut or burn out the rubber, then cut through the outer metal ring without damaging the arm. You'll also need to build a makeshift tool you can use to press in the new bushing - at the very least, use a socket that matches the out diameter of the bushing and use a vise to ...

The short answer is that you should always be guided by the maintenance schedule by the calendar set forth in your owner's manual. It will have a detailed calendar based on your usage profile and setting forth major items based on miles or dates, depending on what's most appropriate. Using my car as an example, there's a moderately major service required ...

You can by an engine from the dealer. Call around the price can very dramatically from dealer to dealer. Some of the high volume (parts sales) dealers will sell over the counter for less than a normal dealer would pay for the engine from GM. One of the dealers in my area sells hundreds if not thousands of engines a year. It was cheaper for my dealer to buy ...

Does it make the most sense to replace an old car's entire exhaust system all at once? Considering your car is almost 10 years old, having to replace all of the parts in the exhaust system does not sound unreasonable, especially if your locality uses any type of road solvent during the winter months (they didn't in Montana where I'm from originally, ...

As Nick stated, try and get one of the same value. If one of the same value is not available, you can always go up in CCA/ah, but never go down. Vehicles are spec'ed with a certain battery because that is what it needs to operate the starter to get the engine going. With a lower CCA/ah, you run the risk of dragging the starter, which can cause it damage. The ...

Assuming you're buying the OEM filter from a Subaru dealer, they should be giving you a new washer with each one. It's an aluminum washer that's sort of folded over on itself so that it crushes. I just did an oil change, so here's a picture of the washers (used on the left, new on the right): Notice that the left one is appreciably flattened. My ...

The oil pan is not a normal wear item, however being so low to the ground it is possible to damage it. As the oil pan is not removed for regular inspection, any decision made by the mechanic should be visible to photograph without tools or disassembly, either as physical damage or oil leaking. Have the mechanic put the vehicle on the lift and show to you ...

Auto Zone's online vehicle repair guides can be found here: http://www.autozone.com/repairinfo/repairguide/repairGuideMain.jsp You'll have to create an account, enter your vehicle and drill down. Curiously it's not found directly under "Engine" but once there, if you look in the left pane you'll see a bullet for "Cylinder Head". A complete list of ...

In my experience, Polyurethane bushes last longer than standard rubber ones, as the plastic doesn't perish in the same way that rubber does. As you mention, there is a price to this, as they are generally harder than the equavalent OEM bushes, however many manufacturers offer a variety of stiffnesses, depending on the intended use - some of the softest ones ...

The tools to do it yourself can all be rented. The job can be difficult and even hazardous depending on the route you take to do it. You can do full strut/spring changes by buying the "quick change" strut assemblies. Or, you can disassemble the strut assembly to only replace the bad parts (commonly the strut and the bearing/top plates). That requires ...

I'd like to preface my answer by saying that I think the OP has asked an interesting theoretical question that deserves a theoretical/hypothetical discussion. In no way should the following be taken as an indication that removing/installing batteries carries low risk of explosion. Take precautions when working around vehicle batteries. The risk of hydrogen ...

I'll preface this by saying I have never changed this bulb in a Camry before ... with that said, the replacement bulb should be a 194 or 168 or 2825 (different numbers for same basic bulb). It looks something like this: Here are the steps I found at this site: 1) First you want to remove base from roof liner. There are 2 clips in the rear...2 in ...
