There’s a lot of difference between your C1500 and others that GMC manufactured over the years. One thing’s the same, though — they all need a fully functional GMC C1500 oil pump to keep the engine lubricated effectively so it doesn’t burn up.

C1500 oil pumps force the oil through the camshaft, cylinders, lifters and more, keeping them all moving smoothly. But, if yours isn’t working, you’re at risk for complete engine failure. The status of the oil pressure gauge on the dash is one sign you have a problem. Ticking or clanking lifters or valves is another. Listen to your truck and head to AutoZone for an oil pump replacement for GMC C1500 today. Trustworthy advice provided by helpful staff and a Loan-a-Tool program for DIY installation are available at the location nearest you to make your repairs easier.
