Why Does My Truck Need Oil & Fluid Services?

Your diesel engine's moving components require proper lubrication to function optimally. With routine oil changes, you can minimize friction, reduce engine wear and tear, and increase fuel efficiency. 

Our technicians recommend an oil change every 5,000 to 20,000 miles, depending on your truck's make and model. Additionally, your transmission and differential require lubricant to keep gears from wearing down and malfunctioning, with a typical service interval of 60,000 miles.

Why Does My Truck Need Coolant Service?

Liquid coolant is at the forefront of keeping your heavy-duty engine from overheating. It absorbs radiant heat and dispels it through the radiator, maintaining optimal combustion temperatures. If you don't change the coolant regularly, it will become less effective and eventually break down, increasing the risk of engine damage. At EIP Diesel Repair, we recommend a coolant flush every 30,000 to 60,000 miles, though every make and model has varying service intervals.
