Aug 28,2017

Changing your own oil in your refrigerated truck with truck refrigeration units can save you time and money. Taking your truck to a maintenance shop could take almost all day after you make an appointment and driving to the shop. After learning how you will never take it to a shop again.

Step 1: Before you change your oil you should run your refrigerated truck with truck reefer units and get the oil warm so that it will gather all the dirty particles. It will also be easier to drain.

Step 2: Make sure you set the parking brake.

Step 3: First you must obtain a floor jack and jack stands. 
Jack the refrigerated truck up using the floor jack. Place the jack in the center of the front brace between the front tires. Make sure that the surface you are parked on is level and stable, so that the jack doesn't move(if not make sure blocks are placed under back tires). Jack the truck up so the front tires are off the ground. For safety purposes, you should also place a jack stand under the brace just inside of the two front tires. This is to make sure the vehicle does not fall on you if the jack fails. Blocking the rear tires will also help eliminate the risk of the jack moving.

Step 4: Get a wrench that fits your drain plug, an oil filter, an oil filter wrench, a bucket to catch the oil, and the oil. 
Be sure to know what type of oil your vehicle requires. If you do not know, you can find this information in your vehicle manual, as well as the oil capacity.

After, take the wrench, and tighten it another quarter to half rotation. This will ensure that the bolt it tightened enough, but not so tight that it is going to pinch the rubber seal.
