Over time, the fluids in this system will become burnt, and the fluid will break down and pick up unwanted particles and debris. Changing this oil is just as important as changing your engine's oil and for the same reason. Metal-to-metal contact wears down surfaces and creates heat from friction, which inevitably weakens the gears and leads to failure. This is all normal, but you will need to have your four-wheel drive system flushed and cleaned from time to time. Industry standards recommend the fluid in these gear cases be changed every 30,000 miles, but please check your owner’s manual for your make and model and their recommendation.

Differentials have a fill plug and a drain plug; we pull the drain plug and remove the fluid. We also drain the transfer case fluid at the wheel. If there is no plug, we will pull the whole cover to remove and drain the fluids. After the fluids have been drained and the plugs and covers inspected for debris, we will replace and seal them properly. We will then add the new fluid to the transfer cases and differentials. This flush on a typical four-wheel drive system can take up to about two to three hours once it gets back to a technician.

Coolant can get old and dirty just like engine oil, just not as often. However, coolant can’t simply be dropped and refilled like engine oil. Even if you drain it, a portion of the old coolant remains; therefore, it is necessary to flush the system to be sure all the nasty deposits are removed. New coolant also prevents expensive corrosion. By doing this service you will have the peace of mind of knowing that your car will remain cool in the summer and eliminate freezing in the winter.

Industry standards recommend this to be done every five years or 150,000 miles. GM recommends a flush every 60,000 to 100,000 miles with a Dexcool fluid system. The Green System Vehicles recommend flushing your cooling system every 45,000 miles. We advise you to check your owner’s manual for the recommendations for your vehicle’s make and model.

We utilize BG Cooling System Cleaner to break up the corrosion and deposits. Then after the flush we will add a BG Super Cool Conditioner to the new coolant to help maintain a clean and fluid coolant. We utilize a flush machine to help with this process. The cooling system flush can take up to two to three hours depending upon make and model and inspection of all hoses and connections.

Moisture can also cause corrosion, which can cause damage. Exchanging the fluid will protect your vehicle against this expensive damage.

Industry standards dictate that power steering fluid should be exchanged as necessary every 50,000 to 100,000 miles to keep your vehicles power steering in the optimal condition and prohibit any issues from starting. We recommend checking your vehicle’s owner’s manual for the proper timing for your vehicle’s make and model.

We utilize a BG Quick Clean fluid to run through the power steering fluid. This breaks down all the improper particles in the fluid so it can be flushed out by our machine. During the power steering flush, we drain, flush, and clean the system, making sure we rotate the steering and move the wheels to get all the buildup removed from the system. Then we will refill the system with the appropriate fluid as recommended. This process can take up to an hour depending on the make and model.
