Per @Eric Urban's suggestion, I found the Technical Manual for the M4A3 tank published in 1942. That tank did use the aluminum Ford GAA 18L V8 engine which produces 500 hp at 2600 RPM! It says: Capacity: 32 Quarts Above 32°: SAE 30 32° to 10°: SAE 30 or 10 10° to -10°: SAE 10 Below -10° : Not Listed Replace the oil every 50 ...

Your fuel economy change is caused by the fact you're not using the same fuel. Fuel changes twice per year from summer blend to winter blend and back again causing a change in the Reid Vapor Pressure (RVP). In summer, the hotter temperature evaporates liquids easier causing more pollution, so it is blended to lower the RVP. This blend is more costly to ...

If your friend is moving your vehicle without your consent and does so deliberately your friend is committing a crime. Vehicle theft. If you are asleep when this happens then consent was not given. I would suggest that you have a police officer have a long discussion with this individual about this. If this individual when moving your vehicle hits another ...

I'll make it very simple for you, Dave. Just remove the relay highlighted, in yellow, from the diagram above. This goes to the starter.

Remove the publicly available key. Make one copy of the key for each person or household who needs to be able to move the car. Give a key to each person and have them sign an agreement that they will not loan their key to anyone else. If the individual is still able to move the car, he probably made an unauthorized copy, in which case you should contact ...

What you've been sent is the radiator for the diesel variant - as opposed to what appears to be the 1.25l Zetec petrol engine in your first diagram. You're correct in that the "main" radiator connections are the same between the two (Despite the confusing placement of the lower hose on the second diagram it is the same hose and hooks up in the same place ...

Both that disc and pad look perfectly normal to me, although I can't see from the photo how much material is left on the pad - but with only 25k on the clock I would expect them to have plenty of life left. You will always get light corrosion on the discs when the vehicle has been sitting for a while (as little as overnight if the weather is damp, a few ...

It's one of the Heated Windscreen connectors. They have a reputation for breaking off on the Ford Focus, because the wipers hit them if they're not routed correctly. It's common for replacement glass companies to not notice that the car has a heated screen, so don't spend any money fixing it until you've confirmed that it still has a heated screen. This ...

Drum brakes are cheaper to manufacture than disc brakes, because there are fewer moving parts and because in the rear the parking brake (which often works by a drum-and-shoe mechanism even on four-wheel-disc-equipped cars) can share a drum with the "regular" brakes. All other things being equal, discs work better than drums, especially in wet conditions. ...

That process you're describing is VERY familiar to me - I do that for people from time to time. The difference is REALLY SIGNIFICANT... and at most it should take you five minutes of actual work per headlight - it's really pretty minimal, with diminishing returns VERY quickly. ALWAYS WET-SAND. Do NOT dry-sand. Start with nothing less than #600 sandpaper, ...

tl dr: Corrosion (once cleaned) is not a huge issue. It is just typical corrosion on the battery terminal. See this image: (NOTE: This is a 6V battery, but the same principles apply.) The blueish color you see is hydrated copper sulfate. When acid vapors escape from the battery, it can cause a reaction with any copper which may be in the terminal. The ...

Use some Sugru on it It's rubbery in consistency so it won't just snap off when you drop your keys. Use a piece of metal or plastic for the "crossbar" and sugru around it.

The first attempt at fixing the sudden shutdown issue was to replace the Electric Motor Cooling Pump. Since it was a recall the dealer replaced it for free. The picture pump above is the "out the factory model". The one below is the replacement model. There is an obvious size difference between both. You can find instructions on how to replace this pump ...

It depends on a ton of things and it won't be linear in most cases. Every car has different things that wear out at different rates and those things affect horsepower differently as they age. Not everything that wears affects power. A coolant hose that wears out might cause the engine to overheat, but it won't affect power until then. But vacuum hoses can ...

You absolutely can! I've painted several of my race cars this way, on a limited budget. The looked wonderful, and I usually wrecked them before the paint was an issue. If you prep very well (all automotive paintjobs are 90% prep work, and 10% spraying) you can get outstanding results. You do need to have some painting experience, even with a rattlecan. ...

It doesn't take as many wires as you think, and they just add additional circuits to the clockspring. The clockspring was introduced with drivers side airbags to maintain a continuous electrical connection for the airbag while allowing the steering wheel to turn. The manufacture simply added a few additional circuits to accommodate steering wheel controls. ...

It sounds like they're trying to take you for a ride to me. I can't see how driving style could cause the slave cylinder to fail - they're separated by a mechanical linkage. I would also dispute that anyone could destroy a clutch with 32k of normal driving - I'd expect it to last at least twice that long. However, a leaking cylinder might cause ...

Cigarette lighters have been standardized for many years now. Even power outlet plugs are pretty much the same in size and shape, though their power throughput may be lower than an actual cigarette lighter outlet. If you are having issues, first thing to do is try a different adapter. If that still fails, check the fuse. If it's beyond that, you'll need to ...

The range switch doesn't think the car is in park. On Fords theres an adjustable cable if you look on the driver side of the transmission there will be lever with a cable attached. Sometimes the clip on the cable fails. if the cable is OK pull the lever all the way into park and it should start. If it doesn't you probably need a new range switch.

You have a short somewhere. The purpose of a fuse is to be the weak link in a circuit. If more current is running through a circuit than it was built to handle, a fuse will self destruct and break the circuit, preventing overheating and possible fire. The most likely causes of a circuit having too much current are too many devices drawing too much power on ...

It seems that you are only worried if the car will leave you stranded, not if it is bad for the car to drive around with (possibly) a bad head gasket. Driving around with a shot head gasket is not optimal as some of the coolant may end up in the engine oil, but being a cheap car and driving short distances it probably is not that big of a problem. The car ...

Could be you. I've heard from several sources that when installing light bulbs you should not touch the glass at all. When you touch the glass, any dirt/grease from your fingers will end up on the glass and will cause the bulb to run hotter than usual. This might cause premature failure. Don't know how much of this is accurate or even if it's true but ...

Yes, the air that is passed through the crankcase ventilation system is metered before it enters the ventilation system. If the pipe is off, un-metered air will be allowed in, which will cause a weak mixture and therefore possible misfiring.

If it has an engine oil cooler, that is most likely the problem, a faulty oil cooler, some are made into the radiator, others have heater hoses running to a remote oil cooler, and a few I have seen are where the oil filter screws on, the oil cooler has a leak into the coolant side. The reason no coolant is in the oil is because it is a high pressure leak, ...

As you wrote, it is unlikely that the supply line of the bulb has a short, but not impossible. Beneath that, it's possible that the return line has a bad connection to the chassis. If an other device uses the same line, the flowing current rises the voltage on that line, and you measure a lower voltage between supply and return line. A bad contact in the ...

If this is a car you are planning on keeping, I'd highly suggest just paying the money to get it fixed. A stop leak may work for a period of time, but it's only temporary. A couple of things to consider with a stop leak is, it usually works great for keeping the coolant from flowing places it shouldn't, but it doesn't work too good at keeping the exhaust ...

As stated in other answers, you really need to get your new housemate to start listening to you. If he doesn't respect your property, do you really want him living with you? With regards to the vehicle, your simplest solution is unplugging something on the ignition side. Historically, you could unplug the king lead (from the coil to the distributor) but ...

The left descending pipe is (or comes from) the exhaust manifold, and ends in a two-bolt flange. The flange bolts to a matching flange on the front end of the exhaust pipe, which runs aft from the flanged connection towards the rear of the car, undoubtedly through a muffler (or two). Gaskets in such high-heat environments are often made of metal; this one ...

It is not likely the quality of the gasoline causing the change. The sensors are unable to evaluate the chemical makeup of the fuel. It could be a change in your driving habits, changes in temperature, the vehicle health, tire pressure, etc. I would not be too concerned. The dash indicator is an estimate only. The computer monitors how you drive, current ...

I wouldn't be too bothered by the fact that it'll need a new cambelt at the next service, but I might use this for additional leverage when negotiating. As to what the odds of failure are, do you feel lucky? I'm pretty sure the Focus has an interference engine so if the belt breaks, the pistons will attempt to occupy the same space as the valves, with ...
