Why do repair shops not want to use my own auto parts?

Keeping your car well maintained is important. And for some people, letting a technician isn’t enough – they want to take the extra step and order their own parts and really be a part of the process. And while that effort is appreciated, there are several reasons why many auto repair shops will not install parts that you bring to them when you’re getting your vehicle serviced.

The easiest way to explain why is to give you some example scenarios.

Let’s say you order your water pump and timing belt off of the internet or purchase them at a

local parts supply house.  When you bring in your parts, you are feeling all happy because you feel like you just saved yourself some money. In this scenario, let’s pretend we agree to install your parts.

One of our technicians gets your car into the bay, and sets it up on the lift. We go to install your part – but oh, wait –the water pump does not fit. Then you’re in a position where we’ve begun labor, and now you’re stuck with a part that doesn’t fit, waiting for days or weeks until you can get the appropriate part from an internet parts retailer or taking time to run back and forth to the parts store to complete the job, all the while the car is stuck in the repair shops bay.

Or say, maybe we installed that part, and six months down the road, you return to our shop and say the water pump and timing belt we installed are making noise and are not working properly. If we had installed your parts – and not our own – then you aren’t covered with the 2 year, 24,000 mile warranty that we offer our customers with our parts. And while yes we do need to sell auto parts in order to keep our shop open, another important reason why we do that is so we can offer the great warranty on the parts.

In this scenario, you would now be paying our shop two times for the same job to be performed, and overall you haven’t saved any money.

Now let’s look at another scenario so you can better understand the hazard of using your own parts, instead of an auto repair shop’s parts.

Say you call the shop to get a price on replacing an oxygen sensor.  You say you have been to a local auto parts house and have the code and they say it’s your oxygen sensor. You are asking us to put in the part that you have, and go off of another person’s word that this will fix your problem with the check engine light.

Then comes in the fact that as an auto repair shop, we absorb the liability when you walk out the door with your car keys in hand. If you were to have someone install a customer supplied part and it’s wrong, it could cost cause further car problems, an accident, or even put your safety at risk.

When you allow Steve’s Auto Repair & Tire to diagnose and replace the parts that we purchase we are guaranteeing your money is well spent.  If the part fails, you will not be paying labor again, nor will you be paying for the part. We as a company have to absorb the expense when a part fails within its warranty time and that is why we use quality parts from our trusted parts suppliers.

(AP) — Punxsutawney Phil saw his shadow Sunday and predicted six more weeks of wintry weather, his top-hatted handlers announced to a raucus, record-sized crowd at Gobbler’s Knob in Pennsylvania.

Phil was welcomed with chants of “Phil, Phil, Phil,” and pulled from a hatch on his tree stump shortly after sunrise before a member of the Punxsutawney Groundhog Club read from a scroll in which he boasted: “Only I know — you can’t trust A.I.”

At approximately 2:45 P.M. on Saturday, February 1st, units with Stafford County Fire and Rescue (SCFR) responded to a reported structure fire in the 100 block of Aquia Creek Road, near Aquia Creek. Callers reported a neighboring residence on fire, and first arriving units marked the scene less than 10 minutes later and confirmed fire and smoke coming from the rear and roof of a single-family residence.

Due to a lack of hydrants in the area, crews had to utilize rural water operations to shuttle water to the scene. Crews worked quickly to extinguish the fire and bring it under control in approximately an hour, despite the roof collapsing.

The residence was not occupied at the time of the fire, and no injuries were reported. The fire is under routine investigation by the Stafford County Fire Marshal’s Office. SCFR units were assisted on scene by Quantico Fire and Emergency Services.

(AP) — Preliminary data from the deadliest U.S. aviation accident in nearly 25 years showed conflicting readings about the altitudes of an airliner and Army helicopter when they collided near Reagan National Airport in Washington, killing everyone aboard both aircraft, investigators said Saturday.
