FixOil Cooler Line Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $254 – $597. The price on any one car depends on the vehicle — the table below shows the range for each.
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.
