Coolant Flush Service in Westmont, IL

Coolant Flush Service in Westmont, IL

There are a wide variety of fluids that flow throughout your vehicle to ensure that it continues to function as normal, and many of them require regular changes. One example of this is coolant, an important liquid that is directly in charge of your engine’s health. We at McGrath Lexus of Westmont would like to tell you more about this!

Coolant Purpose

Those venturing in the Westmont area may notice that doing so puts a lot of pressure on your vehicle's internal mechanics. This usually manifests in the form of intense heat, which is mitigated by the coolant fluid. It is able to do this because it is a unique infusion of two equal parts water and antifreeze. Because of this, it is unable to boil or freeze under natural conditions. This makes it perfect for regulating the temperature of your engine in both the summer and winter. However, with extended usage, it will eventually begin to dissipate over time, leading to reduced effectiveness. When that time comes, you’ll want to postpone your trip along Route 34 and visit our location instead.

Warning Signs

We generally recommend visiting our Service Department around every five years, or around 30,000 miles. This can vary from one vehicle to another, so be sure to go through your Owner’s Manual for details specific to your car. When this time comes to an end, you’ll notice various red flags manifesting during your brief excursions to Hinsdale Golf Club. For example, you may experience fewer miles per gallon or your engine temperature gauge revealing that your powertrain is overheating. But if you want a symptom unique to reduced coolant quality, keep an eye out for a sweet odor emitting from your car’s vents, as this is a direct sign that you need more of this fluid in your vehicle. 

Coolant Flush

Our team here at our location is composed of a variety of certified technicians with plenty of experience to boot. They’ll quickly assist you with whatever you may need. In regards to a coolant flush, they’ll begin by checking on the remaining amount of liquid within the reservoir. If they determine it to be insufficient, the remaining fluid will be drained and replaced with a fresh batch straight from our Parts Department. We also recommend checking out our various service specials, as we often have great deals for you to take advantage of. Otherwise, be sure to schedule an appointment ahead of time so you can be in and out of our location in no time at all!

 

How Often Should You Get a Coolant Flush?

  • You should get a coolant flush around every five years, or 30,000 miles. Be sure to consult your Owner's Manual for more information.

My sales rep, Mel Owens, was absolutely amazing, knowledgeable, friendly, and never pushy. He made the entire process smooth and stress-free. The pricing was fair and transparent, which I really appreciated. No games, no surprises — just a straightforward deal on a great car. I'm in love with my new Outback and couldn't be happier with my purchase. If you're in the market for a vehicle, ask for Mel. You won't be disappointed!

I recently purchased a used acura mdx from here and my experience was great. I purchased it used but they gave me a new car purchase treatment. I didn't feel pressured to buy at all. Jason Sanchez was awesome and made sure I was totally satisfied with my purchase before I left. He went above and beyond for sure. Even though I had an issue with the vehicle they kept their word and got right on it and fixed the problem. I would definitely buy another car from them. Keep up the good work.

I came here to buy a 2021 BMW 330e. I was helped by Glen. He’s is great! He answered all of my questions and was extremely helpful. The cafe there has great food that we were able to enjoy while waiting. We showed up around 10:30 AM and were in, approved, signed, and out in just a couple hours. I honestly can’t believe how painless the process was. They were transparent and up front about everything. They worked with us and made the process a joy. Their inspection process and standards even for a vehicle that is not a Lexus/Toyota is comprehensive and thorough. Any issues they found, they fixed, and I feel so confident in the new (to me) car. I would 100% recommend and would not hesitate to return to buy a car. I know this sounds like a paid review but, seriously, I’m super happy with the process and cannot say it enough. Thank you McGrath!

I am so grateful to Casey and the staff, especially Justin, the general sales manager, who took the time to answer all of my questions and make sure I was making the best decision for me. They were so patient as I thought through all the options and truly had my best interest at heart. The dealership is a relaxing, stress-free environment. Casey is so knowledgeable and always takes the time to figure out the best option and will always find a way to make it work. I also need to mention how awesome Aldo is in the finance department. He makes the process go so smoothly and always makes me feel at ease. I am so excited about my new car and so appreciate Casey and the rest of the staff at McGrath.
