Maintaining your vehicle for optimal performance and safety in Manassas, VA, involves several key components, one of which is the coolant in your car’s system.

Coolant
Coolant plays a crucial role in keeping your engine’s temperature under control as you drive along Signal Hill Road. This fluid prevents overheating and ensures your engine operates smoothly. Ignoring coolant maintenance can lead to engine failure, potentially leaving you stranded. Typically, it’s advised to change the coolant every 30,000 miles, although this can differ based on your vehicle’s specific make and model. To determine the exact interval for your car, refer to the Owner’s Manual for detailed instructions.
Service Department
Upon arrival at our Service Department, our skilled and knowledgeable staff will welcome you and ensure your vehicle gets top-notch care. They are committed to preserving your car's performance for all your planned journeys, whether around town or to places like Stonewall Park Pool. They will start by examining your heating and cooling system to confirm everything is functioning properly. Next, they will check your coolant levels to see if they are sufficient. If necessary, they will replace the old coolant with new fluid and clear out any debris or buildup to ensure your system operates efficiently. This comprehensive service will help keep your vehicle in peak condition as you move through the streets of your city.
Warning Signs
Being aware of warning signs that indicate potential issues with your car's cooling system is essential, so we’ll round this off by giving you an idea of what you should look out for. A sweet, syrupy odor inside your vehicle often signals a coolant leak. Additionally, grinding or knocking noises from your engine can suggest problems with the cooling system. Another strong indicator that maintenance is required is the illumination of the Check Engine light. If you notice any of these symptoms, pay a visit to Sheehy Nissan of Manassas for a thorough inspection and any necessary maintenance. Our team is prepared to assist you with any issues that may occur with your vehicle.

How Often Should You Get a Coolant Flush?

  • You should get a coolant flush done at least once every 30,000 miles.

I am 100% satisfied with the repair service at Sheehy Nissan of Manassas. In particular, Service Advisor Mr. Hadley Bule was extremely professional, kind, humble, and honest in providing the best service. Before visiting Sheehy Nissan, I went to a local repair shop, but they were unable to identify the problem. However, Sheehy Nissan exactly found the issue and resolved it perfectly. After the service, my vehicle feels like new. Thank you so much to Nissan and special thanks to Mr. Blue.

I’ve had a great buying experience from Sheehy Nissan of Manassas. Isaac Bermudez was who contacted me after I filled out a quick online trade in estimate on their website. After completing the trade in estimate online, I spoke with Isaac the next day and ended up driving my new to me 2020 Toyota Corolla Hybrid home! Overall the experience was as easy as it could’ve been, he handled the negotiating, helped with finance options, and we were all happy with the deal on my trade in as well as the price on the car I purchased. Isaac was quick to answer any questions I had regarding the vehicle so I felt confident with the buying process. I would recommend for any sales inquiries or questions regarding trade in acquisition ask for Isaac Bermudez. He took great care of my trade in and newly purchased pre-owned vehicle.

Isaac was a wonderful guy. I got a much nicer car than I’d anticipated being able to afford and he made it happen for me. He figured out what I wanted and he how he could get it for me. It was also a fairly quick and definitely painless experience. They even gave me a great trade in value for my old Jeep which I wasn’t expecting. He knows what he’s talking about and he’s super friendly and kind. Will definitely be coming back next time my family needs anything car related and will pass his name onto my friends and family.

Thank you Daisy for your time and your effort.

I had the very best experience buying a vehicle from Daisy. From the moment I walked in the door I knew I was leaving in a Sheehy car. Daisy met me with a smile and walked the lot with me even as quitting time was upon us. She made sure I knew my satisfaction was her satisfaction and that's greatly appreciated. I usually do not contribute to surveys and reviews but I could not allow this experience to go unrecognized. Thank you Daisy for your time and your effort.
