When to call today
Pull over safely and call if you see:
- A red warning light on the dash, or the engine drops into reduced power.
- The temperature gauge climbing, or steam from under the hood.
- Thick smoke of any color that doesn't clear after the engine warms up.
- A loud knock, or a sudden loss of air pressure on a truck with air brakes.
Other problems, like a slow start, a yellow check engine light or a drop in mileage, can usually wait a day or two. Get them checked before they turn into a bigger repair. Our guides explain the most common ones.
How this site works
Rio Grande Diesel Help is a free referral service. We don't fix trucks. When you call, your call goes to an independent local diesel shop that serves your area. The shop gives you the price and does the work. More in how it works.
