Turbo diesel cars tend to have heavier engines than regular gas cars and because of this tend to experience more stress on their inner components when they're used. To help combat this, it's important to complete regular maintenance like flushing the engine. A flushing will remove any carbon deposits or sludge build-up common in turbo diesel cars that can affect the effectiveness of the engine. The procedure isn't as complicated as it may sound. With the right preparation and a little patience, this is a job you can do yourself.

Step 1 - Prepare Your Car

Allow the engine to completely cool before working on it. This is especially important if you've recently been driving the vehicle for an extended period of time. Then slowly warm it up to normal operating temperature. In cooler climates this may take a bit more time, but it's an important step so don't take any short-cuts. You want to make sure all the oil and other fluids are smoothly running through the engine before trying to flush it.

Step 2 - Drain the Old Oil

Drain the old oil from the turbo diesel car engine according to the manufacturer's directions. Keep the old filter in the vehicle. If you're going to be using a bottle pre-mixed engine oil flush, then you'll want to install a new filter and keep the old oil. When adding engine oil flush, you'll need to drain some of the old oil so that i t doesn't rise above the dipstick's full mark.

While adding engine flush may seem like the easier way to flush a diesel engine, it's not recommended because the flushing substances in the mix can actually be too harsh on a turbo diesel engine and remove all the oil films. Turbo diesel engines work harder than gas engines and the oil films protect the moving parts of the engine from friction and wear.

If you still prefer to use a pre-mixed engine flush, then go to Step 3.

Those who choose to drain the old oil will now need to refill the engine with the lower quality diesel engine oil.

Step 3 - Start Your Car

Run your vehicle at a fast idle, without driving it, for about 10 minutes if you're flushing with diesel oil. If you've decided to use an engine flush, you'll likely need to leave your vehicle running for longer, still at a fast idle and still without driving it. Typically you'll need to keep it running for 25 to 30 minutes or whatever the instructions are on the bottle.

Step 4 - Drain the Oil Again

If you're following the preferred method for flushing a turbo diesel car engine, then you'll need to completely drain the lower quality oil and put in a new oil filter. If you've chosen to use a bottled flush, you'll need to drain the treated oil and put in another new filter.

Step 5 - Add Fresh Oil and Test

Refill the engine with high quality diesel oil and additives, if necessary, and replace the air and fuel filters. Test run the car to see if there are any leaks.
