We weren’t expecting THIS to solve our AC line problem, but here we are…

We tried ordering a replacement part, but it didn’t end up working out, so we tried this instead (also, heads up: this isn’t sponsored, but this part is just that good). 💪

250 years. Some things change. Some things don't.

Hard work still matters. Showing up still matters. Doing the job right still matters. Grateful for this country, and grateful for every customer who trusts us to keep them on the road.

Happy 4th of July from all of us at Certified Diesel.

Both are new 2025 GMCs, yet one is dealing with the 100 degree heat way better than the other…. ❌ and the answer why is not what we expected.

If you have a Duramax and start hearing clattering noises... this is what it might be. ⚠️

If you're having this issue... come in and we can get a valve adjustment done for you. 💪

Call us at 864-345-4568, and let's get it taken care of.

We... weren't expecting this playlist. 😂

Every single one of our guys has a complete different playlist, on all opposite ends of the spectrum. So, tell us: what are you listening to at the shop?

Just got a new shop tool that's working unbelievably well: a pot. 🍳🔧 Turned up the heat on this part to see if it's really broken.
