FixChevrolet Silverado 2500HD — Oil Cooler Line Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $324 – $688. A quote inside that band is normal. Cheaper or pricier isn't automatically wrong — but it's worth asking why.
What this repair is
Many engines and transmissions run their oil through a small cooler via rubber-and-steel lines. The crimped ends age, weep, and eventually spray — an oil leak that appears at the front of the engine bay, or transmission fluid where it shouldn't be. Lines are the usual fix; a leaking cooler core costs more mostly in labor to reach it.
Is your quote fair?
If your quote lands between $324 and $688, it's inside the range where half of all real Chevrolet Silverado 2500HD repairs of this kind land — and the typical job takes about 2.9 hours of labor. Quotes well below aren't automatically good news (economy parts, or related work skipped) and quotes above aren't automatically gouging (trim variants, premium parts, seized hardware) — but both ends deserve questions.
