Why do our technicians put paint marks on these bolts…. 🤔

Those paint marks are a quick indicator that these bolts have been properly torqued and inspected. If the bolt starts to loosen or move, the paint mark will shift and show us the problem before it becomes an expensive repair.

It’s a simple step that helps us keep your truck safe, reliable, and on the road. 💪

Chris’s favorite truck might come as a surprise, but these Fords are pretty reliable once they’re fixed right. 💪

Think your diesel truck is “fine”? A 5 minute check today can save you thousands later. 💰⚠️
Here are 5 things every diesel owner should be checking regularly:

1️⃣ Engine Oil…Low or dirty oil can turn into a very expensive repair fast.
2️⃣ Engine Coolant…Keeping coolant at the right level helps prevent overheating and major engine damage.
3️⃣ Brake Fluid…Your stopping power depends on it. Don’t overlook it.
4️⃣ Power Steering Fluid…Low fluid can lead to hard steering and unnecessary wear.
5️⃣ Transmission Fluid…Check it with the truck running, in neutral, and the emergency brake on.

💡 Bonus Tip…Check your battery terminal ends for corrosion or loose connections before they leave you stranded.
A little preventative maintenance now beats a big repair bill down the line. ✅💪
