I’m Ryan Carter, a certified auto technician with over 12 years of hands-on experience in vehicle diagnostics, engine repair, and preventive maintenance. I’ve worked on a wide range of vehicles, from everyday sedans to advanced hybrid and electric models. Through my work on Tech9AutoRepair, I aim to simplify complex car problems and provide practical, honest, and easy-to-follow advice so drivers can make smarter decisions about repairs, tools, and maintenance. When I’m not working on cars or writing, I enjoy testing new automotive tools and exploring the latest vehicle technologies.

Category: Car Accessories › Hail Protection By Ryan Carter Quick Answer: A car cover for hail uses thick padding or an inflated air layer to absorb impact, plus a snug, strapped fit so wind can’t shift it. Look for real cushioning, an accurate size, and a waterproof outer shell. It reduces dent risk from small to medium stones, but it can’t promise protection from large hail. One surprise storm can leave a vehicle with dozens of dimples and a repair bill that rivals a used-car down payment. A properly chosen hail cover is one of the cheapest forms of insurance…

By Ryan Carter | Category: Car Accessories Quick Answer: A good heavy duty outdoor car cover is multi-layer, breathable, UV-resistant and sized to your exact body style. Look for a soft inner lining, mirror pockets and underbody straps. Fit it only on a clean, dry car, and avoid thin waterproof plastic that traps moisture. Park a car outside long enough and sun, rain, bird droppings, tree sap and wind-blown grit all take turns at the paint. A well-made outdoor car cover is one of the cheapest layers of defense you can add. It only works if it fits properly, breathes,…

By Ryan Carter | Category: Car Accessories Quick Answer: The best cool gadgets for your car fix a daily annoyance without distracting you: a dash cam, a fast USB-C charger, a secure phone mount, a tire inflator and a compact jump starter. Check socket power, fit and local rules first, and keep everything clear of airbags and your sightlines. A gadget earns its place in your car only if you use it every week or it saves you on a bad day. Most cool car gadgets fail that test: they end up in the glovebox next to a tangled cable.…

By Ryan Carter | Category: Car Accessories Quick Answer: For most daily commuters, a 1–2 gallon (4–8 L) leak-proof bin is the best car trash can size. Families with kids should step up to 2–3 gallons (8–12 L) and fit it on the floor behind the seat. Truck and SUV owners can go larger, but anything loose must be secured. Every car owner knows the moment: a receipt, a coffee lid and two snack wrappers slide under the brake pedal on a sharp turn. The fix is a bin, but picking one is harder than it looks. A car trash…

By Ryan Carter | Category: Car Accessories Quick Answer: Resource conserving oil meaning: the bottle has passed extra fuel-economy and emission-system protection tests on top of the base API performance level. Look for “Resource Conserving” inside the API donut, next to a grade like SP, and match the viscosity your owner’s manual specifies. Walk down the oil aisle and every bottle is covered in symbols, codes, and claims. One small phrase sits inside a circular badge and gets skipped by most buyers. It sounds like marketing, but it is actually a test-backed marker that tells you something about the oil’s…

By Ryan Carter | Category: Car Accessories Quick Answer: Read the base code (H11, 9005, 7443, T10) from your manual or the old bulb, buy an LED with the same base, install it with the lights off, and add a CANbus decoder if the dash complains. Then check the beam pattern against a wall at night. Swapping a dim halogen for an LED looks like a ten-minute job. It often is. But a bulb that fits the socket doesn’t always fit the housing, the wiring, or the road rules. This LED car bulbs replacement guide walks you through choosing the…

By Ryan Carter · Category: Car Accessories Quick Answer: The new car must have accessories worth buying first are fitted floor liners, a secure phone mount, a tire pressure gauge with a compact inflator, a windshield sunshade, and a basic emergency kit. Match each item to your exact model, check the manual before wiring anything, and add extras after a few weeks of real driving. The first month with a brand-new vehicle is when the right gear pays off most. Smart additions protect fresh upholstery, keep your phone safely in view, and make roadside surprises manageable. This guide ranks everyday…

By Ryan Carter | Category: Car Accessories Quick Answer: Car fans that blow cold air don’t exist in the strict sense, because a fan only moves air. Real relief comes from pairing a 12V or USB fan with shade, vented windows and, if you want, an evaporative or ice-based add-on. Expect modest relief, not air-conditioning performance. A baking cabin ruins a commute, and a small fan looks like a cheap fix. This guide explains what portable cooling gear can honestly do, which setups suit sedans, SUVs and pickups, and the point where a fan stops helping and a repair shop…

By Ryan Carter | Category: Car Accessories Quick Answer: A marine GPS used for navigation is a water-rated receiver, usually a chartplotter or handheld, that places you on a nautical chart. Choose by screen size, chart coverage, and your 12V power setup. Mount it securely, fuse the power wire, and carry a backup. If you launch a fishing skiff from a pickup bed or cruise coastal waters on weekends, a clear position fix and a readable chart screen turn an uncertain outing into a confident one. This guide covers how these units work, how to power and mount them, and…

By Ryan Carter | Category: Car Accessories › Phone Mounts & Holders Quick Answer: Mount your phone low on the dash beside the steering column, or in the lower corner of the windshield where it is legal. Keep it below your view of the road, within easy reach, and clear of mirrors, gauges and airbag panels. Test the spot from your normal driving posture. A navigation app only helps if you can read it in a quick glance, without leaning forward or losing sight of the road. This car mount positioning guide for navigation covers sightlines, reach, airbag zones and…

By Ryan Carter · Car Accessories Quick Answer: For most families, a low push-along or foot-to-floor ride-on suits ages 1 to 2, while a 6V battery car suits 2 to 3. Check the weight limit, measure your trunk or cargo area before buying, and always supervise rides away from streets and driveways with traffic. A toddler ride-on is really a small vehicle, and it brings the same questions you ask about any car accessory: Will it fit, how is it powered, what is it made of, and how safe is it in daily use? This guide treats riding toys for…

Home › Car Accessories › Free Diagnostic Scan Guide By Ryan Carter | Category: Car Accessories Quick Answer: Yes. AutoZone’s Fix Finder reads check engine, ABS, and maintenance light codes at no charge in most U.S. stores, and staff can also test your battery, starter, and alternator. You get trouble codes and likely repair areas, not a full diagnosis, so treat the report as a starting point. An AutoZone diagnostic scan sounds almost too good to be true: a free answer to the question every driver dreads when an orange light appears. It is genuinely useful, but only if you…
