How to Use Engine Degreaser

Working on a car can be a messy job. And while auto repair isn't brain surgery, care must be taken to keep grit and dirt from getting into the open engine. For this reason, it helps to use degreaser on an engine before undertaking a major repair operation. Your job will come out better, and you won't get too dirty.

Difficulty: Moderate

Instructions

1. Locate a suitable area with access to water and a hose. Degreaser can stain the underlying area so should not be used on a driveway or other cosmetically important place. Do-it-yourself car washes can be used.

2. Ensure that the engine is cool. Degreaser should not be sprayed on a hot engine. If it is too hot to comfortably hold your hand on, wait until it cools further.

3. Spray degreaser liberally onto the entire engine, suspension and undercarriage. It may be necessary to lift the car. If so, use ramps or jack stands for support. Try to avoid spraying degreaser on electrical components such as the distributor, battery and alternator.

4. Wait five to 10 minutes or follow the directions on the can. It may be necessary to brush areas where grease has combined with road dirt into a caked-on mass.

5. Spray off the engine. A low-pressure spray is best. If low pressure isn't available, cover sensitive electrical components with a plastic bag.

Tips & Warnings

• Caked-on grease and dirt should be removed with a screwdriver or other flat-bladed instrument prior to applying the degreaser. If spraying onto the undercarriage, spray there first. Start at the back and work your way forward; otherwise it may drip into your hair and onto your clothing.
• Never crawl beneath a vehicle supported by just a jack. Always use a jack stand or ramps. Wear eye protection, especially when spraying off, since degreaser can splatter. Always check local, state and federal regulations concerning the use of such products. Never use at a car wash that prohibits the use of engine degreasers (some do).
