Why Timely Engine Diagnostics Matter

Your engine is the heart of your vehicle, and when something goes wrong, it affects every part of your drive. That’s why accurate engine diagnostics are key to protecting performance, preventing costly damage, and staying safe on the road.

We hear it all the time:

“My gas cap light is on.”
“My check engine light won’t go away.”
“My car is cranking but not starting.”
“It smells like something’s burning under the hood.”
“My battery light is on, but I just replaced it.”

These may seem small, but they’re often symptoms of deeper issues, from misfires and overheating to alternator failure or failing spark plugs. The sooner you bring it in, the faster we can fix it.

Our Warranty

We offer a 3-year, 36,000-mile warranty on parts and labor. When we say we stand by our work, we mean it.

We’re No LongerJust Tires

Our Extensive Engine Diagnostics & Repair Services

At Kreager Tire and Service, we use high-end diagnostic tools including Autel, Snap-On, and Pico lab scopes to accurately diagnose engine problems. We test, verify, and explain everything we find with honesty and care.

Check Engine Light Diagnosis

From common codes like P0300 (random misfire) to complex sensor errors, we quickly identify what’s causing your check engine light to come on and recommend the right fix.

Misfire Diagnostic & Repair

Engine misfires can cause rough idling, poor gas mileage, and long-term damage. We identify whether it’s a spark, fuel, or compression issue and repair it with precision.

Engine Tune-Ups & Spark Plug Replacement

Regular tune-ups keep your engine efficient. We replace worn spark plugs, check coil packs, inspect ignition components, and ensure your vehicle is running at peak performance.

Starting & Charging Diagnostics

If your car won’t start, the culprit could be the battery, starter, or alternator. We test your full electrical system, including terminals and grounds, and handle any necessary repairs.

Battery Replacement & Light Diagnosis

A faulty battery or charging system can leave you stranded. If your battery light is on or your vehicle struggles to crank, we’ll diagnose and replace it using reliable, top-brand batteries.

Radiator & Cooling System Repair

An overheating engine can cause major damage. We test your radiator, water pump, thermostat, and cooling fans—and repair or replace components to keep your engine temperature under control.

Fuel System Diagnostics

Issues with fuel pressure, dirty injectors, or failing fuel pumps can affect performance. We inspect your system thoroughly and clean or replace parts as needed for optimal flow and efficiency.

Gaskets, Seals & Minor Engine Repair

We service common engine wear items like valve cover gaskets, oil pan seals, timing cover gaskets, and more—fixing leaks and preserving engine health.

Engine Replacements

We offer complete engine replacements using high-quality parts and expert installation. We’ll walk you through your options and ensure everything is installed to factory specifications for maximum performance and reliability.
