How To Tune Up A Jeep Wrangler

Visually check and top off all engine related fluids. The engine oil level is checked with a dipstick that extends through a tube and down into an oil pan at the bottom of your Jeep. Pull the dipstick from the tube and wipe with a clean hand towel. Replace the dipstick all the way back in the tube and remove again. This time you can read the dipstick for the oil level. There are two marks, ADD and FULL. If needed, add oil, but be sure not to overfill the engine. Check the engine coolant, it is in a clear plastic reservoir. DO NOT remove the radiator cap while engine is warm! You should be able to see through the reservoir if more fluid is needed. Check the window washer fluid which is also in a clear plastic container but is blue. If needed, add fluid.

Replace the spark plugs one at a time. Use the Gap Gauge to make sure the new spark plugs are measured to the correct gap size as the old ones. When you remove a spark plug, there is a small arm, an electrode, at the top of the spark plug. Use the Spark Plug Wrench to remove the old plugs and install the new ones. You may want to use some of the compressed air in a can to spray away any dirt or material around the spark plug hole.

Perform a visual inspection of all the hoses and belts on your Jeep. Check the brackets as well as connectors. If a hose looks a little distorted in shape or color, give it a little squeeze. Rubber hoses should be on the hard side. If it feels a little soft or gummy, it's time to replace it. Visually inspect the belts. There are several grooves across the belts. If there are cracks across most of the threads, time for a new belt. Using the Battery Brush, gently clean any dried crust that may be on or around the battery terminals. Be sure not to get it in your eyes!! Battery acid is not a joke!!

Check the tire pressure. Properly inflated tires not only prevent accidents but can help out your pocketbook next time you are at the pump! Printed on the side of each tire, the manufactors have placed what pound of pressure the tires should be inflated to. Use the Tire Pressure Gauge to check your tires. If needed, add air.

Warnings

  • close Never remove the radiator cap, coolant cap, or remove spark plugs while engine is still warm!!
  • close Do Not get dried battery acid in your eyes nor inhale!!
