Mix 50% water/ 50% antifreeze. Use distilled water
What should you do when you are checking your coolant?
Check the level at the coolant recovery tank first
Let engine cool
Never open a hot radiator cap
What are the most common Brake Fluids?
(but DOT 4, DOT 5, and DOT 5.1 are available)
Check cap or owner's manual for the correct type.
What type of fluid are used on manual transmissions only?
Commonly DOT 3 brake fluid, but always check the owner's manual
What fluid check is on RWD (rear wheel drive) and 4WD (4-wheel drive) vehicles?
Where will 4WD trucks have their differential check plugs?
The front and the rear of the truck
Power Steering Fluid
Use the type that is recommended in your owner's manual.
the hydraulic fluid that transmits the power in power steering.
What type of steering systems do not have power steering fluid?
Electric Power Steering systems
Add only distilled water
Wear safety goggles and gloves
When refilling the liquids in your car ALWAYS remember to:
Not run fluids low, but also don't overfill
Always refer to the owner's manual for fluid specifications
Dispose of fluids properly
What functions do various fluids provide to vehicle components?
Fluids provide cooling (antifreeze), cleaning (windshield washer), lubricating (oil), and sealing to vehicle components.
What is the process to check engine oil?
1. Shut off the engine and park on a level surface, 2. apply parking brake, 3. open the hood and look for oil dipstick, 4. To get an accurate reading check the oil when the engine is cold, 5. Pull out the dipstick and wipe it off with a paper towel and reinsert it into the engine, 6. Remove again and read (3.8-4.7 L). Most automobile engines have an oil capacity between four to five quarts. Vehicle manufacturers suggest adding oil when the engine is low one quart.
What is the color of clean oil?
What is the color of dirty engine oil
What is the process to check automatic transmission fluid?
1. Check ATF when it is hot with the gear selector in park, 2. park on a level surface and apply the parking brake, 3. Pull out the dipstick and wipe it off with a paper towel, reinsert it completely, 4. Remove again and read, 5. ATF should be between the "full cold" and the "full hot" marks.
What is the process to check antifreeze (coolant) level for a Recovery Tank?
Engine must be cool, check the level in the coolant recovery tank/expansion tank, usually translucent with a "full cold" (or MIN) and a "full hot" (or MAX) mark or a "cold fill range". If low, remove cap and add the manufacturer's recommended coolant type and mixture.
What is the process to check antifreeze/coolant level in a radiator?
Remove the cool radiator cap and check the level in the radiator, never remove a hot radiator cap, fluid should be at or near the top, if low add the manufacturer's recommended coolant type and mixture as needed. Reinstall the cap.
What is the difference between the two common types of antifreeze?
1/2 water and 1/2 antifreeze and concentrated antifreeze. 1/2 water and 1/2 antifreeze is an antifreeze that is already mixed while concentrated antifreeze is 100% antifreeze therefore you need to add distilled water to the antifreeze.
What are some safety precautions when handling brake fluid?
Use extreme caution when handling because brake fluid is harmful to your eyes and if spilled on a vehicle's finish, it will strip paint. Always use the correct type of brake fluid because it can cause damage to the car.
What is the process to check power steering fluid?
Shut off the engine and located the power steering reservoir, the cap and the dipstick are commonly one unit. The dipstick usually has a "full hot" and a "full cold" line. Remove the dipstick, wipe it off, reinstall, remove again, and note the reading. Using a clean funnel, add fluid as necessary.
American Petroleum Institute
The largest U.S. trade association for the oil and natural gas industry.
Automatic Transmission Fluid
The fluid used in vehicles with self shifting or automatic transmissions. It is typically colored red or green to distinguish it from motor oil and other fluids in the vehicle.
Make sure the coolant is not orange. Only use yellow coolant.
The manufacturer recommended antifreeze for GM and other vehicles with aluminum radiators, heater cores and water pumps and aluminum engine components in contact the coolant. It has no silicates which tear up water pumps.
It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting syrup.
Extended Life Coolants
The highest quality virgin ethylene glycol for freeze and boilover protection, and a patented hybrid organic acid corrosion inhibitor package to protect cylinder liners from cavitation and liner pitting and your engine from rust and corrosion.
How to Check Motor Oil
1. Shut off the engine, 2. apply parking brake, 3. open the hood and look for oil dipstick, 4. To get an accurate reading check the oil when the engine is cold, 5. Pull out the dipstick and wipe it off with a paper towel and reinsert it into the engine, 6. Remove again and read (3.8-4.7 L). Most automobile engines have an oil capacity between four to five quarts. Vehicle manufacturers suggest adding oil when the engine is low one quart.
a lubricant consisting of chemical compounds that are artificially made. Synthetic lubricants can be manufactured using chemically modified petroleum components rather than whole crude oil, but can also be synthesized from other raw materials.
an American brand and trade name for automotive aftermarket products, especially lubricants such as motor oil and motor oil additives. The name began as an abbreviation of Scientifically Treated Petroleum.
Society of Automotive Engineers
When referencing motor oil weight, you are actually referring to the viscosity grade or the tendency of a liquid to flow slowly or quickly. The Society of Automotive Engineers (SAE) developed a grading system to designate the viscosity level of single grade and multigrade motor oils.
(often referred to as PG) is the third "product" in a chemical process beginning with propane, a byproduct of fossil fuel (oil refining and natural gas processing) and also found in nature as a byproduct of fermentation.
A company that sells coolant and antifreeze.
An American oil company incorporated in 1917 that expanded into petroleum refining, marketing and transportation, natural gas gathering and the chemicals sectors.
No Transmission Dipstick
If the vehicle does not have a dipstick, the transmission fluid must be checked at the transmission. This requires lifting the car on four jack stands; it must be level to check the fluid. There will be a fill plug on the side of the transmission case.
No Oil Dipstick
Newer cars have no oil dipstick. Not a good idea.
When do you check/change your antifreeze?
Most of the time it is 30,000 miles but check the owner's manual because it is different in different cars.
