Boulder Auto Repair

Air quality has certainly become a hot issue in our modern Boulder world. We install air filters on our ventilation systems and in our vacuum cleaners. There’s a filter that cleans the air going into our family car’s engine — so why not one for the air in the passenger compartment? Foreign and domestic auto makers haven’t been ignoring the issue.

The sensor has determined that the engine needs a little help cooling down to a safe temperature. A hose connects th ... read more

Driving on bald tires is like playing roulette. Though you may be fine today, eventually your luck is going to run out. The Feds don’t have any laws for tread depth, but 42 of the states, and all of Canada, do have regulations. They consider two-thirty-seconds of an inch to be the minimum legal tread depth. Two other states, including California, consider one-thirty-second to be the minimum and six states have no standards at all. Call us at John’s Auto Care; (just call 303.442.2932) to find out what your requirements are in the Boulder, CO area. Since 1968, U.S. law has required that a raised bar be molded across all tires. When tires are worn enough that this bar becomes visible, there’s just 2/32” of tread left. But does that older standard give Boulder auto owners enough safety? Consider this: Consumer Reports recommends tire replacement when tread reaches 4/32”. And the recommendation is backed by ... read more
