Finally I found the right mechanic shop I will use as long as I live in this area. They are very knowledgeable and do the business honest. I replaced engine coolant in other mechanic shop which is close to my work place. Unfortunately right after I pick up my vehicle the engine overheated after 10~15 min driving. I get diagnosis from the manufacturer dealership, and they recommend to replace water pump, radiator, and thermostat which will cost more than $3000. I gave the diagnosis report to Du Fresne's Auto Service. Du Fresne's Auto Service did its own diagnosis and find the real culprit. The culprit was air pocket inside radiator and thermostat . The final cost including the testing for diagnosis was less than $600. I am very happy to find trustworthy auto shop! Unfortunately it is hard to find auto shop that does the business in right way these days.
Thank you Youngki for giving us a 5 star review. It makes me, as the owner, very happy that our employees are doing the repair properly and treating our customers with respect, as it should be.
