Sometimes it just takes a little testing to find the real problem!

This fan came in not working at all. A little diagnostic testing quickly showed us it was definitely having some problems!

Don’t just throw parts at it — test it, diagnose it, and fix it right the first time. That’s how we do it at Underdog Mechanical!

If something on your vehicle isn’t working like it should, give us a call and let’s get to the bottom of it!

🥶 COLDER WEATHER IS COMING… IS YOUR VEHICLE READY?

Cooler temperatures can bring out problems that your vehicle may have been hiding all summer. A little preparation now can save you from being stuck on the side of the road later!

Common cold-weather problems to watch for:

🔋 Weak or dead batteries — Cold temperatures are hard on batteries, especially older ones.

🛞 Low tire pressure — As temperatures drop, so can your tire pressure. Check your tires regularly, including the spare!

🔥 Heating & defrost problems — Don’t wait until that first freezing morning to find out your heat or defroster isn’t working.

💧 Low or weak antifreeze/coolant — Proper coolant protection is important when temperatures start dropping.

🚗 Hard starting or rough running — Colder weather can expose issues with batteries, glow plugs, fuel systems, ignition components and more.

🧊 Wipers & washer fluid — Make sure your wipers are in good shape and your washer fluid is ready for winter temperatures.

⚠️ And if you DO end up stranded…
Keep a few basics in your vehicle: jumper cables or a jump pack, flashlight, phone charger, blanket, water and a basic emergency kit. If your vehicle breaks down, get as far away from moving traffic as safely possible, turn on your hazards and call for help.

Don’t wait for the first cold morning to find out your vehicle wasn’t ready!

Let us help you catch the little problems before they become big problems—or leave you stranded.

A simple broken wire caused ALL kinds of problems!!!

Sometimes the biggest headaches come from the smallest things. This little broken wire was enough to cause multiple issues and had us tracing down the source.

That’s why proper diagnostics matter. Instead of guessing and throwing parts at it, we find the actual problem and fix what needs fixing.

Electrical issue? Warning lights? Something just not acting right?

Bring it to Underdog Mechanical and let us get to the bottom of it!

🚨 CLUNK when you take off?

That thump or clunk when you accelerate might be your vehicle telling you it’s time for some motor mounts!

Worn or broken mounts can cause:

Clunking or banging when taking off

Excessive engine vibration

Movement when accelerating or shifting

Extra stress on other components

Don’t wait for a little CLUNK to turn into a bigger repair!

We don’t just replace parts — we find the problem.

🍂 🍁 Summer is about to collapse into fall, and cooler temperatures are on the horizon!

Before we know it, cold mornings will be here — so we thought this was a good time to look back at just a few of the jobs that have rolled through Underdog Mechanical this year.

🔧 Crank-no-start diagnostics
🔧 High-pressure oil leaks
🔧 Engine replacements
🔧 Transmission problems — from hard shifts to no shifts
🔧 Oil leaks… and more oil leaks!
🔧 Fuel system issues, including failed injector hard lines
🔧 Dirty fuel filters filled with dirt and water
🔧 Brake problems, dragging calipers & overheating
🔧 Axle seal repairs
🔧 Exhaust leaks that turned into much bigger repairs
🔧 A/C system failures
🔧 CCV filter issues
🔧 Electrical and sensor problems that took some real detective work to find

And that’s only part of what we’ve seen!

The change of seasons is also a great reminder that preventative maintenance can help catch small problems before cold weather turns them into big ones.

Now is a good time to get on our schedule for:

✔️ Battery & charging system checks
✔️ Coolant/antifreeze testing
✔️ Brake inspections
✔️ Oil & filter changes
✔️ Fuel filter replacement — especially on diesels
✔️ CCV filter service
✔️ Belt & hose inspections
✔️ Tire and tread checks
✔️ Fluid inspections
✔️ Heater/defroster checks
✔️ Glow plug and cold-start concerns on diesels
✔️ A good overall inspection before winter travel

Don’t wait for that first freezing morning to find out your vehicle wasn’t ready for it.

Get ahead of winter and get your preventative maintenance appointment on the books with Underdog Mechanical! 🔧

Because we’d much rather help you prevent a breakdown than have to rescue you from one.

NEW WEEK, NEW PROBLEMS TO SOLVE!

It’s Monday, and we’re kicking off another busy week at Underdog Mechanical!

Oil leaks, oil leaks, and MORE oil leaks!

Diesel owners — when was the last time you changed your CCV filter? If you had to stop and think about it… it might be time!

A neglected CCV filter can contribute to excess crankcase pressure and those pesky oil leaks nobody wants to see.

Start the week off right — take care of your truck, and it’ll take care of you!

Quality diagnostics. Quality repairs.

This fan came in not working…

A little testing found it was having some problems.
And by “some problems,” we mean it definitely wasn’t going to fix itself!

Sometimes it takes a little digging to find out what’s really going on. That’s why at Underdog Mechanical, we don’t just throw parts at a problem — we test, diagnose, and find the cause.

🎥 Check out the video to see what we found!

Been chasing an oil leak and just can’t figure out where it’s coming from?

Sometimes the source isn’t where you’d expect!

This sensor was actually leaking oil through the plug and out into the wiring harness!

Oil leaks can travel and make the problem look like it’s coming from somewhere completely different. That’s why proper diagnosis matters — find the source, don’t just treat the symptom.

We diagnose it. We find it. We fix it right.
