Purchase the largest air compressor you can afford. You will be happy you did. The ones with oil are quieter than the ones without, but the quantity is what matters most. In my opinion, the more the merrier.
One of the best tools I’ve ever had is a wheeled battery charger, starter, and tester. That retails at Sam’s Club for around $90. (Schumacher). Twenty years old is mine.
Except for the spark plug socket, which is 5/8″ and the tires and wheels, which are not metric, I have never discovered anything on the car that employs SAE rather than metric. It’s a nearly fully metric vehicle. I have relatively few SAE tools, and my family owns five Toyotas and a Hyundai.
Both the cooling system combustion gas test kit and the cooling system pressure leak tester are excellent tools.
Which bolts does Toyota use?
According to Toyota’s grading system, the class (strength ratings) vary from 4T to 11T. However, carrying only SAE Grade 8 (sometimes branded 10.9) spares is the simplest method to get around this. The possibility of not having the strength of bolt or nut necessary when replacing with a spare is eliminated because this is normally the highest strength for a non-stainless bolt or nut. Find a bolt in the same service that is close by, make note of its class stamp, and tighten it to the companion bolt’s torque if at all possible (not the torque for the highest class). Ideally, when you arrive home, swap out the bolt or nut for one of the proper kind.
Another thing to keep in mind is that Toyota employs hexagonal bolts with distinct torque specifications for both hexagon head bolts and hexagonal flange bolts. I would simply bring extra flat washers and hexagon head bolts (to simulate a flange bolt in a pinch).
We are currently at the bolt length. Depending on the application, Toyota employs bolts of varied lengths (same diameter/pitch). I keep 6 mm bolts, 8 mm bolts, 10 mm bolts, 1-1/4 inch bolts, and 12 mm bolts, all of which are about 3/4 inch long. With the exception of the 12 mm size, I have 6 of each nut, washer, and bolt of the aforementioned sizes in my travel toolbox.
Are automobiles SAE or metric?
Metric bolts have become a hot topic among vehicle repair technicians and manufacturers since since Ford’s Pinto engine and Cadillac’s 8.2 L Eldorado engine were introduced in the 1970s. Metric bolts are now preferred by the majority of domestic autos over SAE inch-sized bolts. Metric bolts must be used in your new car rather than the usual SAE bolts. The purpose of this post is to give you a simple manual for identifying your bolts.
It should go without saying that bolts come in a variety of sizes, shapes, materials, tensile strengths, diameters, wrench sizes, and pitches. It is already obvious that no two bolts are exactly alike. An automotive repair maker can determine which bolt is specialized for which use thanks to these characteristics. A long bolt could get in the way of your car’s other components. On the other side, if a small bolt is used somewhere else when a long bolt is needed, there is a danger that it will break. The incorrect bolt placement will not only impede your car’s motor from operating to its full potential but will also result in a variety of unwelcome problems for both your automobile and your wallet.
The type of bolt is identified by a marking on the bolt. The tensile strength and the amount of force that a specific bolt can withstand are stamped on the bolt’s face. Although a bolt with a high tensile strength should be able to handle more torque, it is still advisable to keep a torque chart close by and adhere to its recommendations.
You may have no idea that your bolts might be either hard or soft. So first, you should be aware of this if you ever see a bolt without any markings. A low carbon steel component with a tensile strength of more or less 64,000 psi won’t be indicated by a bolt. They are referred to as “soft bolts” if you discover one. Whenever there is a need for light manufacturing, soft bolts are typically used.
Grab a bolt and examine the raised slots on its body first. If there are three slots, these are Grade Five slots with a 105,000 psi tensile strength. View the graph below:
If you ever find yourself unsure of which bolt is your “eight grade” and which is a “grade six,” you can always pick up a size tool from your neighborhood hardware store.
Your number of threads per inch will increase as the pitch decreases. American bolts come in two different varieties: United National Fine Thread and United National Coarse Thread. The distance between the crest of one thread and the same location on the crest of the following thread is known as the thread pitch. You will be able to identify the type of your bolt if you comprehend this.
A coarse thread is less likely to strip since it turns in and out more quickly. However, fine threads enhance torque, which improves their ability to hold.
- Different markings are used on metric bolts. Bolts marked “M” or “ISO M” on top have a diameter more than 6 mm. Additionally, metric bolts may be identified by numbers like 5.8 or 10.9. They are the bolt’s size but not quite as strong. The strength of the bolt will increase with the higher the number.
- Another method to tell a Metric bolt from an SAE bolt is by size. If your metric bolt is size M12X2, the threads on it have a main diameter of 12 mm, and their pitch, or the space between them, is 2 mm. Based on the separation between the threads, ISO categorizes metric threads.
Sorting bolts by size, shape, and measurement makes it simple to distinguish between various types of fasteners. It can be nerve-wracking to figure out how to tell a Metric bolt from an SAE bolt made in the US. However, if you know which bolt to use to repair your car, you can make it run like Usain Bolt did again.
