It sounds like the approach to solving your problem so far hasn't been very systematic or "evidence based" – at least the list of parts replaces suggests that the people working on it have been using a "shotgun" approaching, replacing parts in hopes that one (or more) of them will solve the problem. Start off by doing basic checks: Is there hot water ...

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 ...

Number one answer is always Head Gasket. The reason is that there are oil and water passages in close proximity, being separated by a gasket (which might just be flimsy paper or rubber, but is often steel or copper) sandwiched between two pieces of metal with (usually) different thermal expansion rates. This means that any time your engine gets far enough ...

There are many leak down testers on the market. You can actually make your own with some hardware store parts and a fish tank. Operation of "most" leak down testers The procedure of operation depends on whether or not you have the cylinder head attached to the engine block or not. If the head is attached, your leak down tester should have an attachment ...

Basic Functionality Image In order to illustrate a typical Multimeter The Multimeter is specifically a multifunction tool. By definition it combines several, well defined instruments and multiplexes the controls for simplicity. Inputs Majority of Multimeters will have 3 input terminals. Typically you will only use COM and V/mA/Ohm input (often Black and ...

There are a few questions in there, so I will try to address them all. The Bueler Time Delay relays are unlike the vast majority of other relays you will find. The difference is that these relays are so-called "smart" relays. They have embedded circuitry that handles the triggering as well as the timing functions of the timed relay. For most relays (i.e. "...

1. How do I operate a leak down tester? Directions differ depending on whether it's a one gage or two gage system. It basically gets down pulling a spark plug, getting that piston to Top Dead Center (TDC), threading the tester into the spark plug hole, hooking up compressed air (at a minimum pressure), bringing the cylinder pressure up to a set amount, and ...

It wouldn't be the fuse which is causing the power drain, but the circuit the fuse is there to protect. (This is the reason why the copied area you have posted has 5 "Not Helpful" votes against it.) The fuse is only a conduit. It transmits electricity. When the circuit transmits too much electricity, the fuse heats up, then "pops", not allowing anymore ...

The computers in a car are constantly monitoring the operating conditions and sensors that are in the car. When a test fails or something goes out of a pre specified range a DTC is set. The biggest misconception about a DTC is that it tells you what to replace, it does not. A DTC tells you what test failed or what parameter went out of range. This ...

I'd say there are many pros and cons for newer and older as a starter (I went older, 84 Nissan 300ZX Turbo). Newer (lets say 15 years or newer so we are talking about 1996+ which should have ODB2) Pros OEM Parts Availability More Cars in Junk Yard to pull parts from (dependent on production numbers, but still more than older models) Less wear and tear ODB2 ...

Much of what makes wheels appear dirty is brake dust. Brake dust is wear particles from the brake pads and rotors (or from linings and drums, in the case of drum brakes). The braking effort in most vehicles is not equally distributed between front and rear wheels--this is by design. Generally the front wheels do most of the braking work, since weight ...

When I looked online, here's what I found about the location of the MAP sensor in your car. As always, a picture is worth a thousand words: From looking at other info about that car it's port injected, not throttle body injected (individual injectors on each cylinder, not just one on the throttle body). As far as I know there should never be fuel in that ...

Pull the spark plugs and inspect them. Oil-fouled spark plugs will look wet and black.

This is what I can think of, in my limited knowledge. Overlaps with some existing answers. Trying to limit to things that aren't obvious, also trying to think of direct physical causes rather than things that may or may not trigger certain ECU software to make an explicit shutdown decision (I assume there's a lot of variation here, so it's kinda hard to ...

There are a number of possibilities here, including: bad tire bent rim unbalanced wheel bad shock absorber mount other suspension parts loose/worn/missing steering rack faulty wheel bearing warped brake rotors alignment problem Although you have just put on new tires, there is still a possibility that they weren't properly balanced or that they were, but ...

There are other factors that affect the start stop feature. I am not sure on that exact model but generally the following things will keep the car engine from shutting off: Coolant Temp too high, or too low The engine has not ran for at least two minutes The AC is on and not in the economy mode Low Vacuum Battery charge low High current draw on the 12 volt ...

The fact that the light bar lights up means that it works. If the fault is consistent, I'd be more tempted to look for the fault at the brake pedal - where the switch for the light is. As your existing brake lights work correctly, next step is to see whether they use the same switch, as per @Brian's comment. It may be that the LED bar has been wired in ...

After much deliberation on going to repair shop, I figured I would at least poke around as it could not make anything worse. Here was the problem. The negative terminal wire soldering point was loose. I fixed it this way: Unplug the LED array.

You asked What do these compression figures mean Response Not that much when the engine is cold. Background Based upon the information you have provided I see no indication that the rings are bad. You aren't burning any oil You do not have oily carbon buildup on your spark plugs Bad rings will almost always give you those two symptoms, if they ...

I am presuming this is a gasoline engine. If so, the symptoms sound very much like the throttle internals are dirty. If gunge builds up on the butterfly valve, it can restrict the air required for a smooth idle when the butterfly is closed, so the engine ECU needs to open the Idle Air Valve more that it thinks it should have to and you get into a cycle of ...

If you are hearing the starter turn (typical starter whir), the most probable problem would be the one way clutch has gone out. It's the part of the starter with the teeth on it which engages the starter ring gear. If the solenoid has gone out, the starter motor will not spin, because the solenoid is the part which forces a large copper washer into the posts ...

I'm not a diesel mechanic but after a quick search the number one cause of no starts on the 6.0 is lack of oil pressure. The injectors need 500psi minimum to operate. This indicates there is not sufficient high pressure oil to properly operate the injectors. There needs to be a minimum of 500 PSI ICP pressure and it should always match the desired ...

If buying one of the pre-assembled sets is not an option, the following answers will assume you will keep your tools in some form of carry bag... You can begin by alienating all your sockets, and sorting them. Purchase a couple of socket rails, which can be had for cheap, and snap them on. Insert these into your bag. Next, alienate your wrenches and sort ...

If the picture you have attached is similar to the starter on you car, then the power to the starter motor is only delivered if the solenoid operates, so the solenoid must be working. However, the shift lever labelled in the picture, that pushes the pinion forward to engage with the flywheel may be broken, that would explain your problem. Your problem ...

You can test your rings and head gasket with a leak down tester Checking your spark plugs as shown in @Zaid's post is the first order of business. You will see it on the plugs. Now, if you do see an oil fouled plug, you will need to identify the source of the oil. Possible Sources of Oil Intake valve guide seal Rings Head gasket PCV valve Any of the ...

If you've changed the calipers and the pedal now goes all the way to the floor, chances are that you've introduced air into the system whilst you had the calipers off. To fix this, you need to "bleed" the braking system. At each brake caliper / wheel cylinder there is a bleed nipple or bleed screw. The basic procedure is to start at the wheel furthest ...

While this is an educated guess, I'd put money on the fact this is oil coming from the oil filler cap. It appears the cap isn't sealing completely, or possibly the cap isn't screwed on tight enough. If tightening it a little more doesn't work, you'll need to replace the seal on this to get it to stop. The seal itself may be an o-ring type, or it could be ...

It would be good to ask the mechanic to explain to you how they are sure that it is the head gasket – head gasket problems often share symptoms with other problems. One way that a head gasket failure could cause overheating would be if the gasket failed between a combustion chamber and the cooling system. Combustion gasses could leak into the water jacket ...

It's just in front of the front passenger side door, under the dashboard. It might be stuck down behind the carpet a ways.

I strongly support PetroEkos's suggestion of a tool bag. I'll go even further and suggest that you invest in a separate job bag: i.e., take some time before the task to reach into your (now nicely organized) selection of tools and make a good guess as to which tools you're definitely going to need. You usually won't get the inventory exactly right but you'...
