Case Study: The 15-Point Inspection

One Tuesday morning, David brought his Ford F-250 Diesel Pickup to the shop for an oil change. Pretty basic stuff. He grabbed a coffee and waited in the lobby.

After changing the oil and filters, the mechanic did a standard 15-point inspection and saw that the brake fluid was a little low. So they looked into it a bit more closely.

The team found a slow fluid leak in the break line. When asked, David said that he had noticed pushing the brake pedal a little harder recently. But the warning light didn't came on, so he didn't worry too much about it.

If the mechanics hadn't been thorough, the leak could easily have resulted in an accident. Instead, the they were able to replace the brake line and get David and his Ford F-250 Diesel Pickup safely back on the road the same day.

The technicians at Matt's Caddy Shack have years of experience working on standard 4-wheel drive (4x4) vehicles as well as all-wheel drive (AWD) vehicles. AWD is a full-time 4-wheel-drive system (all four wheels receive torque from the engine simultaneously) that employs a center differential that allows each tire to rotate at different speeds.
We understand the special needs of these vehicles. These are some of the services we offer.

Frequently Asked Questions

What’s that bump, clunk, squeal, or screech? 

We get some variation of this question about 20 times per day! Unfortunately, it's hard to tell exactly what's wrong without the proper diagnostic equipment. We've got the tools to do it, so bring you car in and we'll let you know exactly what's causing your mystery sound.

Does it hurt my truck if I drive with the check engine light on?

It is possible, but unless the light is flashing then you're usually okay for a short distance. It's more likely that you'll experience reduced performance. We do recommended that you come see us right away, to see what exactly is wrong before it can do long-term damage.

What’s the correct tire pressure for my car?

The recommended tire pressure is set by the tire manufacturer. Tire pressure is measured in PSI (pounds per square inch) and you can find your recommended pressure on the side of your tires. Properly inflated tires will help you get better gas mileage and reduce tire wear.
