How Much Does a Thermostat Cost to Replace?
A stuck thermostat causes overheating or a cold-running engine. A Cranbourne West specialist explains the cost.
What drives the cost
Thermostat cost is mostly about access — some are easy, others are buried under the intake or part of a housing that’s replaced as a unit. The part itself is usually modest; labour and coolant make up much of the cost.
On many European engines the thermostat comes as a housing assembly, which affects the price.
What the job involves
We confirm the thermostat is the issue (stuck open = slow warm-up/no heat; stuck closed = overheating), replace it, refill with the correct coolant and bleed the system.
