What Does Coolant Do and Why Is It Important?
Coolant is just as every bit of important as the other oils and fluids pumping throughout your truck—as a mixture of water and antifreeze that circulates through your truck's engine, coolant is the frontier of regulating engine temperature and preventing overheating and poor engine performance. Coolant also helps protect the engine from corrosion, provides lubrication to the water pump, and prevents the formation of mineral deposits. That’s why we suggest to all our customers to enlist in regular maintenance of the coolant system as it’ll help ensure the longevity and performance of your truck.
Signs Your Truck Needs Coolant System Repairs
Over thousands and thousands of miles on the highway, your truck’s coolant will begin to deteriorate, resulting in engine damage and reduced performance. If you notice any of the following signs, it's time to bring your truck to our experts for coolant system repairs:
- Engine overheating
- Low coolant level
- Sweet-smelling exhaust
- Discolored coolant
- Rust or corrosion in the radiator or hoses
We suggest you get a coolant flush every 30,00 to 60,00 miles to keep your fleet’s performance high and prevent unnecessary damage to your trucks’ components.

Great experience from beginning to end. We had never used Bus & Truck of Chicago and what a great surprise! Angela made the whole process worry free, from the estimate to the final product.


Bus & Truck of Chicago is excellent! When my company's truck needed repairs, I took a chance on Bus & Truck Chicago and it really paid off. They were able to fix all the mechanical and body issues in three days, saving us a ton on rentals.


Our experience with B&T has been wonderful so far. Our lift stopped working. We weren't able to use our bus. Angela and her staff were absolutely spot on in all aspects.


Very professional, great work, customer service was outstanding, we wouldn't take our truck anywhere else.


Took my truck here for an alignment, they did an amazing job, fast in and out, definitely would recomend them!!!


They fix everything. They have no issue with you showing up with the part and changing whatever part you want. Not like other shops that insist they diagnose the issue.


"Wonderful company to deal with. Very professional and accommodating to our company’s needs. Service is fast and efficient. We have brought 5 trucks over for repairs in the last 3 months and have NOT had 1 issue with the service or the repairs. Cannot be happier with this company."
