Talk to Ken.
Find out what's up.

Tell him what the car's doing — a noise, a light, a leak, whatever. He'll give you a plain-language first read: what it's probably pointing at, whether it's safe to keep driving, and the exact tool (if any) to check it with yourself.

Browse it myself

Before you start

This is a free first look, not a real diagnosis — a real diagnosis needs hands on the car. Ken will tell you his best guess and whether it's safe to drive. For anything brakes, steering, overheating, or anything that smells like smoke or fuel, he'll always tell you to stop and get it looked at, never "probably fine."

$50 diagnostic gets Thomas out to actually confirm it — free if it turns out to be over his head.

Browse by symptom

What's the car doing?

Open the one that matches. Each one tells you what it's probably pointing at, whether it's safe to keep driving, and the exact tool to check it with if there is one.

Warning light on the dashboard
Check-engine light, solid (not flashing)

Something triggered a stored code — could be minor or real. Safe to drive carefully in the short term, but don't ignore it. Get it scanned when you can.

Check-engine light, FLASHING

An active misfire is happening right now and can damage the catalytic converter. Stop driving it and get it looked at.

Oil pressure light (red oil can icon)

Urgent — low oil pressure can destroy an engine in minutes. Pull over safely and shut the engine off. Check the oil level with the dipstick if you can do so safely. Don't keep driving on this light.

Battery / charging light

The charging system isn't keeping the battery topped up — you may have limited driving time before it drains. Get it looked at soon; don't plan a long trip on this light.

Brake warning light

Always treat as urgent. Could be low fluid, the parking brake left on, or a real hydraulic problem. Get this looked at before driving again.

TPMS (tire pressure) light
Check with a tire pressure gauge against the number on the sticker inside the driver's door frame — not the number on the tire itself. Low pressure is a simple, safe fix. Still on after airing up? A tire may be losing air slowly and should get checked.
A fluid leak or spot under the car
How to check
Slide a piece of white cardboard or paper under the car overnight, then check the color and texture with a flashlight.
Bright green, orange, pink, or blue and watery

Coolant. If the temperature gauge has been climbing too, don't keep driving. If the gauge is normal, get it checked soon.

Brown to black and slick/oily

Engine oil. A few drops after parking overnight is common on older cars; a real puddle isn't. Check the level with the dipstick. Low? Top it off if you have the right oil and get the leak checked soon. Oil light also on? Stop and get it looked at.

Red or pink and thin, near the front

Could be power steering or transmission fluid. Get it looked at soon — don't ignore a transmission fluid leak.

Clear water, especially in warm weather

Almost always normal AC condensation. Not a problem.

Dark brown, almost syrupy, near a wheel

Possibly brake fluid. Treat as urgent — get this looked at before driving again.

A noise
Squealing when braking

Often just the brake pad wear indicator doing its job — designed to squeal before the pads are actually gone. Get it checked soon; not necessarily an emergency yet.

Grinding when braking

Metal on metal. The pads are gone — get this looked at right away.

Clunking over bumps

Usually a worn suspension part. Not usually an emergency, but get it looked at — it affects how the car handles.

A rhythmic ticking that speeds up with the engine
Could be as simple as low oil — check the dipstick that's already in the car. Fine and it's still ticking? Get it looked at.
Squealing or chirping, especially on startup or with AC on

Usually a worn or loose accessory belt. Not urgent short-term, but get it looked at before it fails.

Loud rattling that comes and goes, especially over bumps

Often just a loose heat shield — a thin metal panel around the exhaust. Annoying, not dangerous. Mention it when you book.

Won't start
Nothing at all — no lights, no sound
Almost always the battery or a loose/corroded connection. Look at the battery terminals with a flashlight — white or greenish crust means corrosion.
Dashboard lights on but just a click or nothing when you turn the key
Usually the battery or starter. If you have jumper cables and know how to use them safely, a jump start will tell you fast whether it's the battery.
Engine cranks (turns over) but won't actually start

This is a fuel or spark problem, not a battery problem — a jump won't fix it. There isn't a safe visual check for this one. This needs a professional look.

Overheating
Temperature gauge climbing toward red, or steam from under the hood

Pull over safely as soon as you can and shut the engine off. Do not keep driving. Do not open the radiator cap or coolant reservoir cap while the engine is warm or hot — a hot cooling system is pressurized and can cause a serious burn. Let it cool fully, then call for help or a tow if you're not comfortable checking it yourself.

Tire issues
Uneven or worn tread
Push a penny into the tread grooves, Lincoln's head down. See all of his head? The tread's worn and the tire needs replacing soon. A tire tread depth gauge gives you the exact number if you want one. Wear that's worse on one edge can point to alignment or suspension — mention it when you book.
A bulge or visible damage in the sidewall

Don't drive on it — a sidewall bulge can fail without warning. Get it replaced before driving again.

Vibration that gets worse with speed

Could be a tire balance issue or something in the suspension. Not usually an emergency, but get it checked.

The only tools Ken ever names

Hardly any special tools, on purpose.

If a real check needs more than this, the honest answer is "get it looked at" — not a tool list. Everything here is a few dollars or already in the car.

What Ken won't guess at

Some things just need hands on the car.

Brake hydraulics, the transmission, hybrid or electric high-voltage systems, exhaust restriction, AC performance, and anything electrical beyond looking at battery terminals — these all need real tools and training. Ken's honest answer for every one of these is the same: book the diagnostic.

Book the $50 diagnostic
  • Brakes beyond a visual/sound check
  • Transmission slipping or shift quality
  • Hybrid or EV high-voltage systems
  • Exhaust restriction / catalytic converter
  • AC and heat performance
  • Electrical faults beyond battery terminals

Talk it through with Ken.

Free, no appointment, no pressure. If it's something real, book the day right there in the conversation.
