Thermostat Replacement Cost
RepairPal Fair Price EstimateLearn more
RepairPrice Estimates are based on the estimated time for the repair, labor rates charged by trained automotive professionals, and prices for quality parts.
These estimates are designed to show a range of fair prices, instead of a single price, because there is more than one part that is appropriate to use in each repair, and more than a single mechanic who is qualified to do the repair.
Each estimate is customized for your vehicle and geographic area. Estimates exclude applicable taxes, diagnostic charges and disposal fees.
The entire cooling system should be inspected and tested when the thermostat is replaced.
A high-quality OEM thermostat should be used. Poor quality thermostats may not function properly and can cause damage to the engine or components of the emission system.
A thermostat that is stuck closed will cause the vehicle to overheat.
If the new thermostat does not immediately resolve engine temperature problems, the cooling system needs to be checked for other issues.
A thermostat that is stuck open can cause the engine to run colder than normal and set the Check Engine Light. It may also cause poor fuel mileage and the heater to blow cool air.
