I bought a school bus a year ago and brought it in to begin my personal routine maintenance, as I am converting it to a tiny home. We fixed a numerous amount of things (all of which were legit: oil change, filters, etc). And they informed me that it would be a good idea to do a coolant flush too, considering the coolant that was in it from the school district was for gasoline engines. I told them after I removed the back heater, I would. No need to buy extra coolant after all. I took it back the other day to get the coolant flush and slowly but surely I am replacing old, worn out parts. Every time I have come in, my experience has been nothing but top notch. They take their time, they explain what parts work with what and why they are important, and they teach me about my bus so I can give it the absolute best care. I stumbled upon this shop and I am so thankful I did. This is a mechanic you can trust.
