engine diagnostics

When something goes wrong with your vehicle’s motor, professional engine diagnostics can pinpoint the issue quickly and accurately. At Toole's Garage, our technicians use advanced diagnostic tools to identify engine problems and recommend the necessary repairs to restore your vehicle’s performance.


Most cars have an onboard computer system that monitors engine performance and emissions. When an issue is detected, a warning light—such as the check engine light—may illuminate on your dashboard. Our team at Toole's Garage can look into it and find diagnostic trouble codes, perform in-depth inspections, and provide precise solutions to get your vehicle back on the road.


Engine Diagnostics FAQs

What are common signs that my engine needs diagnostics?

If your check engine light is on, your vehicle is misfiring, stalling, experiencing poor fuel economy, or making unusual noises, an engine diagnostic test can help determine the cause.


How long does an engine diagnostic take?

A basic diagnostic test typically takes under an hour, but additional time may be needed depending on the complexity of the issue and the repairs required.


Will an engine diagnostic tell me exactly what’s wrong?

A diagnostic scan provides trouble codes that indicate which system is affected, but further inspection from our mechanics is necessary to determine the exact problem and the best repair solution.

When it comes to wheel safety, lug nuts don’t always get the attention they deserve. These critical fasteners are what keep your wheels securely attached to your car, and they need to be tightened to a very specific level of force—known as torque. Get it wrong, and you're risking more than just a loose wheel.

It’s difficult to drive anywhere in the Bay Area and not see a lot of Subaru vehicles. Whether it’s the Subaru Crosstrek, WRX, Outback, Forester, or Ascend, Subaru vehicles are everywhere. At Toole’s Garage we are big Subaru fans. Subaru vehicles are built for the great outdoors, and of course California provides plenty of opportunity for on-road and off-road adventures. All wheel drive (AWD) comes standard on many Subaru models, and can provide consistent traction whether you are on a muddy road, or skiing in the Sierras. If a roof rack did not come standard with your model, it’s easy to add. And of course, interior space is pretty generous, especially if you drive an Outback or Ascent – you can stow plenty of camping and hiking gear. At Toole’s Garage we can provide your Subaru with the maintenance it needs to provide you with a reliable ride – wherever your adventures take you. We highly recommend regular oil change – it not only improves performance and extends engine life, but it also allows us to inspect various sub-systems of your Subaru to catch any impending problems (for example, older Subaru models were prone to oil leaks). And if a long summer trip is in the cards, we definitely suggest bringing it in for a checkup. Being a full service auto repair shop, Toole’s Garage can provide your Subaru with routine maintenance services, diagnostics, as well as major repairs. If your Subaru needs new brake pads, has the check engine light “on”, suffers from transmission problems, or needs major engine repairs – we can make your vehicle healthy again. Whether you have owned your Subaru for a long time, or have recently acquired one, bring it to our San Carlos auto repair shop – we will keep your vehicle in peak condition. Call us to make an appointment, or you can make an appointment online, on our website.
