How To Clean Your Car’s Engine: 5 Simple Steps

When it comes to vehicle care, having it washed, detailed, and refilling washer fluid seems to be the extent of what you can DIY, right? Surprisingly, this isn’t always the case. You can perform several maintenance tasks yourself to keep your car from sputtering and coughing while on the road. Here are five simple steps to clean your car's engine compartment and motor.


Step 1: Prepare Your Engine

Remove debris harbored in the grill, hood, and vents. A small hand brush will do the job perfectly, but having access to a compressed air container can speed up the process. After removing the debris, cover the sensors, exposed wiring, distributor, and spark plug areas.


You can use small plastic bags and tape to cover sensitive areas to avoid water trailing in.


Step 2: Loosen Grease

Next, start your vehicle and let it run for five to ten minutes. Doing so can shake accumulated oil and grease from engine components. Warming your engine can also facilitate the degreasing application and cleaning process.


Step 3: Apply Engine Degreaser

Using a water or citrus-based degreaser, apply the solution from the bottom up to avoid dripping. Allow the degreaser to soak for three to five minutes, then use a parts brush to remove heavy soil. Remember to be extra careful with how you spray the degreaser as it can negatively affect your fenders, hood, and grille.


Step 4: Wash Your Engine

After degreasing your engine, use a regular garden hose to wash off the residue. Avoid using a high-pressure nozzle during washing to prevent damaging electrical connections.


Step 5: Dry Your Engine

Your engine emits enough warmth to self-dry after washing, but you want to use a microfiber towel to wipe it dry. After drying your engine, spray an engine cleaner for extra protection and buff to shine.

Choosing the Right Suspension for Your Driving Needs

By Tony Mers • 29 Oct, 2024
The suspension system impacts many aspects of your vehicle, from ride comfort to vehicle handling. Whether you want to enhance your vehicle’s performance or enjoy a smoother drive, review these tips for choosing the right suspension for your driving needs. Learn About the Different Types of Suspensions Start your search by familiarizing yourself with the different types of automotive suspensions. Independent suspensions, such as MacPherson strut and double wishbone setups, can improve ride quality. Alternatively, solid axle suspensions provide durability and load-bearing capabilities. Understanding these options will help you match the suspension type to your driving needs. Consider the Way You Drive Another tip is to find a match for your driving habits. For example, a performance-oriented suspension with stiff springs and shocks may be best if you enjoy spirited driving and frequently take corners at high speeds. Conversely, a standard suspension is better if you primarily use your car for daily commuting and long highway drives. Evaluating your driving style will guide you toward a suspension that enhances your experience behind the wheel. Determine Your Car’s Weight You must also find a suspension system that supports your vehicle’s weight. Every suspension has a weight rating, and ignoring it can damage your vehicle and put you in danger. Check the manufacturer’s specifications to confirm that the suspension you’re considering will tolerate your vehicle and additional cargo or modifications. Think About Where You Travel When looking at suspensions, you should consider where you drive your vehicle. If you frequently take rough trails or uneven surfaces, an off-road suspension with increased ground clearance and durable components will serve you well. On the other hand, you should turn to a standard suspension if you mainly drive on city streets and highways. Tailoring your suspension to your driving environment enhances safety and driving pleasure. Make It Work With Your Budget While you may feel tempted to splurge on top-tier suspension systems, keep your budget in mind. High-end suspensions offer superior performance and durability but come at a premium price. Conversely, you may be able to find more affordable options that provide substantial improvements over stock suspensions. Assess your financial situation and set a realistic budget to get the best value without compromising on quality. Considering these factors will help you choose a suspension that makes your driving experience more comfortable and enjoyable. If you need to repair or replace your current system, Advanced Vehicle Technology Services can help. With our suspension service , you’ll enjoy smooth rides in your car once again and have more control while steering.
