We all want to save money on auto repairs. For beginners or people who are not confident in their home mechanic skills, deciding whether to do a repair yourself or visit an auto repair shop can be difficult.
Should you do it yourself or visit an auto repair shop?
Some simple auto repair jobs can be completed at home if you have the time, the right instructions, and the proper tools. If you are not confident after reviewing the instructions, do not attempt the repair. Bring your vehicle to a professional shop instead. Safety should always come first.
Replacing a Headlight Bulb
Many halogen headlight systems use bulbs that load into the back of the lens. The process usually requires little or no equipment.
Remove the wiring harness
Open and secure the hood, then locate the bulb holder behind the headlight. Remove the wiring harness, which may be secured by a metal clip, plastic catch, or screw cap. Release the fastener carefully and slide the plug free.
Remove the old bulb
Hold the bulb at its base and pull it out. Some bulbs may need a slight rotation before they release.
Install the new bulb
Handle the new bulb with a clean cloth or tissue. Oils from your skin can shorten the bulb’s life. Holding the plug end, insert the bulb fully into the headlight and make sure the rubber gasket is no longer visible.
Reconnect the wiring harness
Reconnect the plug and replace the clip, catch, or screw cap. Turn on the headlights to confirm the repair.
Replacing a Broken Exhaust Strap or Hanger
A loose muffler may clunk beneath the vehicle, or a badly damaged hanger may allow the exhaust to hang low. Exhaust straps and hangers are rubber supports that can lose elasticity over time.
Locate the damaged exhaust strap
With the vehicle safely supported, visually trace the exhaust pipe to the muffler. Check for broken or stretched rubber exhaust straps and inspect the other hangers while you are underneath the vehicle.
Remove the faulty strap
Remove the damaged strap from the mount attached to the vehicle and from the mount attached to the muffler. Make sure all pieces of the failed strap are removed.
Install the replacement strap
Attach the new exhaust hanger to the upper mount first. A helper can hold the muffler while you connect the lower side. If working alone, support the muffler securely and take care not to place yourself under an unsupported vehicle.
Mechanic tip
A crescent wrench with a hole in its handle can sometimes help stretch an exhaust hanger over its mount. Only use this technique when the vehicle is securely supported and the tool can be used safely.
When to call a professional
Do not attempt a repair if you lack confidence, the vehicle cannot be supported safely, the repair involves a safety-critical system, or the problem is more complex than the instructions describe. Sanford’s Auto can help with auto maintenance and repair when you prefer professional service.
