How much does it cost to fix a Jeep coolant leak?

Fixing a Jeep coolant leak typically costs $150 to $400* for a simple hose or clamp repair, while a water pump or radiator replacement usually costs $400 to $900*. A leaking heater core is the most involved repair, often costing $600 to $1,200* due to the labor required to access it behind the dashboard.

The cost mostly depends on where the leak is and how much labor it takes to reach it. A leaking radiator hose or a loose clamp is one of the more affordable fixes, since the parts are inexpensive and the labor time is short. A radiator itself costs more to replace, both because the part is pricier and because it often requires draining and refilling the entire cooling system, along with properly disposing of the old coolant.

A failing water pump adds labor time because of where it's mounted on the engine, and on some Jeep models, it's driven by the timing chain or a serpentine belt system that has to be partially disassembled to reach it. This is also a case where many shops recommend replacing the thermostat and coolant at the same time, since you're already in that part of the engine, which affects the overall system more than the water pump alone.

Heater core repairs sit at the top of the cost range because the heater core is buried behind the dashboard, and reaching it often requires partially removing dash components. This is more labor-intensive than almost any other cooling system repair, even though the part itself isn't particularly expensive.

Catching a leak early, before it causes an overheating event, keeps your total cost closer to the lower end of these ranges. Letting a small leak run for months can lead to a damaged water pump, a warped part, or worse, significantly raising the bill. The only way to know exactly what your Jeep needs is a hands-on inspection, since guessing based on general pricing won't tell you which specific part has failed.
