Good afternoon. My name is Tom Burns snuff. I’m a certified master mechanic film bedding, Pennsylvania. Today we’re going to talk about how to buy fuel treatments. Now, mark, we have today you kind of get a little confusing. You’re walking or local parts store and I was just shelf after shelf of different fuel treatments. Um, a lot of them do basically the same, same function. There are differences amongst them and I’ll go over them a little bit. Here you have three separate fuel treatments for diesel engines, all of which do basically the same thing, but some have, this one’s basically removes water on a few of the diesel fuels jelled up. This is a good one here. This one’s an octane booster here depending on what you’re looking for if you just don’t get in the power that you want to have your diesel engine, this is a, uh, a supreme product right here.
Um, just, just a condensed conditioner and anti jail. As I said, it all depends on what, what purpose you’re looking for. If you’ve got a gas-powered gas powered engine, you just looking for regular fuel injection. This product right here, two plus two from Burchell works excellent. So intake cleaner, fuel injection cleaner if you’ve got water in your fuel system. This ISO dry works good is there are tons of different products that make the same thing. But if you have a water problem, ISO drive works for Y’all. Good. Um, overall the best product I’ve found so far is from Lucas. Lucas makes a ton of products and the supreme in their line, but uh, this one pretty much does just about everything. When it comes to a gas motor dump. One of these in every other time you get, you get your gas stream and it cost about four or $5. You get local parts store, like I said, an excellent product. It, all these products they have out there, they all have different purposes. The best thing to do if you have something in mind as to what you’re looking to get out of a fuel treatment is rich in each individual bottle. Um, they all serve different purposes. Um, if you still have any questions after that and you can’t make up your mind and local parks still help you out and get you on the right track.
Why a vehicle doesn’t start, can be a complicated question, but in many cases, we have to start our diagnosis with some of the basics. And so there are basically two things that we look for first and at is does the vehicle have spark and does it have fuel? Those are probably the two most common reasons why of the vehicle doesn’t start. So this vehicle here, we’re going to do our preliminary checks to determine if that’s one of the reasons why it doesn’t start. So first thing we’re gonna do is we’re going to hook up a fuel pressure gauge to the Schrader valve, a test port on the fuel rail. That way when we turned the ignition on, we’ll be able to tell if the vehicle actually has fuel pop operation. Of course, that’s very important as always when dealing with gasoline. Uh, be careful not to spill the gasoline.
I’m anything hot and keep a fire extinguisher close at hand. The next thing we’re gonna do is we’re going to, we know that you know, this will prove whether or not the fuel pump works. We need to know whether or not the, uh, computer is sending signals for the vehicle to inject. So I’ve disconnected one of the wires, um, from one of the six fuel injectors on this car, I’m inserting a little test light is called annoying light. And this way when we crank it over, we should get some indication as to whether or not that signal is being sent. Lastly, we need to know if the vehicle has spark. So what we’re going to do is disconnect one of the spark plug wires from a spark plug and we’re going to install a spark tester and see whether or not it has sparked. So now what we’re going to do is we’re going to crank it over and see which one of these things that we have. So first off, we’ll just turn the key on and see what happens. All right, so you’re going to need to focus on that. Ready for that shot came up to 40 PSI. Hopefully, you got that with the movement.
Can we turn the key on? It came up to 40 PSI and at indicates that the fuel pump works, and that should be enough. You’ll pressure to actually have this start to vehicle. The next thing we’re gonna do is we’re going to crack the vehicle over and we’re going to check and see whether or not the Lloyd light blanks and that’ll give us some indication of whether we have signal coming from the computer to turn the injectors on and off. No, I like blanked. And that indicates that we’re good in a good signal from our computer and it gets, the computer’s probably conscious and so that’s a good sign.
A starter is essentially a very powerful 12-volt motor that is designed to turn over your car’s engine to allow it to start. Uh, when you turn the key on your, your ignition 12 volts goes to the solenoid on the starter motor. Um, this solenoid does two things. It allows voltage to go to the starter motor itself, which causes it to spin. And it also engages a gear on the shaft of the starter motor, which meshes with the flywheel on the engine. And so when the flywheel engages the starter motor gear, uh, it turns with the starter motor.
Now once the engine is running and you release the key, the solenoid retracts and the gear disengages from the flywheel and the engine is running some signs of a starter motor. Failing may be that the gear does not engage the flywheel, in which case you would hear a whirring sound, what the engine would not turn over if the starter motor doesn’t turn over at all. It could be a bad starter motor, but it could also be a dead battery or a bad cable or a bad ground connection. Um, the best way to test a starter motor is to hook up a connection or directly to the starter motor to bypass the cable and verify that there are no issues in the wiring harness.
Do you know for sure that your headlights are aimed properly? If they illuminate only the street right in front of your car, they’re probably too low and if other drivers are flashing their high beams at you, they’re probably too high. Here’s how to find out for yourself on a level ground park your car with the headlights facing a wall or garage door about 25 feet away. Now the highest point where the light shine on the door should be about the same or maybe a little bit lower than the height of the headlights themselves measured from the ground and it is perfectly normal for the driver’s side headlight to be a little bit lower so it doesn’t blind oncoming traffic for owners of older Honda’s Acuras in some luxury models. Check for a bubble level over each headlight. That can help set the vertical height, but if you do that, make sure the car is on a level surface to begin with. To that end, always check the height with the car loaded the way you will be driving it. Most of the time that’s because load in the trunk can change the height. If your headlights are aiming to lower high, your mechanics should be able to realign them relatively quickly using adjustment screws under the hood.
Just like with almost any new gadget or appliance, each brand-new vehicle comes with a manual. It doesn’t provide the basic instructions on how to drive your vehicle-you should have already learned that in driving school. What an automobile owner’s manual provides are explanations on how to use the automobile’s different components and features, such as the windshield wipers, defroster, turn signal lights, etc. And depending on the automobile’s manufacturer, the manual may also contain tips and reminders on basic automobile maintenance (like when to replace your tires), defensive driving (appropriate use seat belt and airbag), and responsible automobile ownership.
However, don’t confuse an automobile owner’s manual with an automobile repair guide. If the first deals with the basic how-to in operating an automobile’s different systems, an automobile repair manual deals with, well, automobile repair. Like an automobile owner’s manual, a repair manual may still contain illustrations, instructions, and tips on how to use and maintain your automobile, but it’s more focused on providing comprehensive instructions in system repairs and automobile parts replacement. And if you think that automobile repair has a very wide coverage that it should be hard to put them all in a single manual, you couldn’t be more correct.
If we’re going to compile all kinds of repairs one can do in an automobile, we’d probably be able to produce literally tens of thousands of pages of automobile repair instructions. That’s why automobile repair manuals-whether in print or soft/online copy-come in different kinds. There is the generic automobile repair guide that covers basic troubleshooting, maintenance, and repair of the most commonly replaced components such as turn signals, windshield wiper inserts, and fuses. And because they’re generic, they can be referred to for repairing different vehicle makes and models.
If there are generic repair manuals, there are also vehicle-specific repair manuals. These basically have the same content as the generic manuals. But because they’re specifically made for certain vehicle makes and models, they could provide instructions on more complicated and vehicle-specific diagnoses and automobile repairs.
