Engine repair service near Affton, MO

Very shady business... Had my car for about a week trying to work on emissions problems... They ended up blowing my engine while taking the car out for a drive in an effort to get the emission controls to register! Car was running fine when it was dropped off for repair and ended up having to be towed to the scrap yard! Stay Away!!!

A parts store and a machine shop run by people that actually know what they are doing. This isn't one of those crappy chain stores.

I want to thank everyone at North Belt automotive for doing a great job on my car. They were really fast and professional I brought my car into the shop at 4:40pm Friday(the shop closes at 5). They allowed me to wait inside with my toddler son until my ride came, which unfortunately was running late. They called me by 11:30 Saturday evening. If you needed anything done to your car I would definitely prefer this place!! -Arika Ellis

cleaned the throttle body on my 08 silverado but didnt know about the calibration being thrown off after someone manually pushes the flap by hand instead off using gas pedal so after truck ran like crap at 2000+ rpm called about 15 differant shops around town all pointed me to dealer so dealer said they would do the idle relearn for $165 USD??? ok last resot spartan autoworx said sure bring it in they would do it for free so came in no wait hooks up his scan tool within 3 mins the relearn was done truck runs fine so all u chevy truck owners dont push that flap in by hand or shops will tell you that u need $100's of dollars of usless parts and are gonna send u to the dealer in the end but just call up spartan first they are the #1 auto computer guys i love this place

Worst customer service ever. They charged me $70 for a Diagnostic test that had the same information on it as the emissions test that they had just run on my car. They did add an additional part as a necessary replacement although the part wasn't bad. After a friend pointed out that this part wasn't bad, they stated that it was simply a 'suggestion'. I think they should have been more specific although there was no paperwork to be specific on. I got a receipt for my $70. Autozone's free diagnostic tests at least give you some paperwork. When I expressed my dissatisfaction, I was told that I knew nothing about car repair and I was probably lying about how useful the test was. Riiiiiight. The owner really argued vehemently with me about returning my money so I guess he needs it more than I do. By the fact that he works another job and the run-down appearance of this location, I finally stopped trying to get a refund on the most useless and outrageously stupid diagnostic test I've ever had. If you want to be treated with respect and common courtesy, go somewhere else. If you want a company that believes that the customer is always right, don't go here.

Great people work here. I took in an old 1972 351C block because of some stuck bolts I couldn't get with my tools at home. They got it off with no problem, they didn't charge me for anything. I had planned on paying for the use of the tool and a few minutes but they wouldnt let me. Definitely where I am taking my business from now on.
