Here at McGrath, we get questions for the service department all the time! We like to take some of these and feature them in videos for those of you that might have the same questions!

First, let’s introduce you to Preston Valdez! Preston is a Service Advisor at our McGrath Buick GMC Cadillac KIA location in Hiawatha. He was promoted just this year from years as a Certified Technician to an Advisor! Preston is our Go-To for answering FAQs because he knows his stuff and gets straight to the point! He has even been featured on KGAN Local News, demonstrating Winter Weather Prep!
This week we gave Preston some less frequently asked questions but, nevertheless, important and interesting!
- How does All-Wheel Drive really work?
- Can I swap wheels from one make/model vehicle to another? (See Above)
- When should I service a vehicle that I drive less than 2,000 miles per year?
Unlike the 4×4, 4-Wheel Drive System, which can be turned on and off manually, AWD kicks on when the modules tell it to. This makes for added boost in traction! But I’ll let Preston tell how All-Wheel Drive systems technically work…
See our “How does AWD work?” video here:
In our “Swapping Wheels From Different Make/Models” video Preston tells you exactly what we need to check before we can perform the service! Plus! Did you know that it takes a little more than removing and placing lug nuts on the wheels to swap them out on a different truck? The example we used in the video was taking the wheels from a Silverado and putting them on a GMC Sierra. Preston explains bolt patterns, tire pressure monitors and alignment are all key in making a successful swap! Watch that video at the top of this page!
Lastly, the more common question of the three: “I put less than 2,000 miles on my vehicle in a year -when should I service it?”. This question is asked by customers who simply don’t drive often, whether that is due to alternative transportation, work from home, or other reasons. Sometimes it’s from customers asking about their second vehicle that they only take for a spin on summer weekends. Either way, the answer is the same and you can check out Preston’s advice for that here:
