A replacement thermostat for a 2018 Dodge Grand Caravan typically costs about $20–$60 for the part, with the total installed price usually ranging from roughly $150 to $350 depending on labor and part choices.
To understand what drives that price, it helps to know which engine you have, whether you buy aftermarket or OEM parts, and whether the job requires a full thermostat housing, new gaskets, or a coolant flush. Below is a breakdown of typical costs and the factors that influence them.
Cost breakdown: parts and labor
The following figures give a general sense of what you might pay. Prices can vary by region, shop, and whether you choose OEM Mopar parts or aftermarket equivalents.
- Thermostat price (aftermarket, standalone): typically 10–40 USD
- Thermostat assembly with housing or OEM part: typically 40–90 USD
- Gasket/seals (and related small parts): 3–12 USD
- Coolant (optional if you need a refill or flush): 2–8 USD per quart; flush kits or processes may add 10–20 USD
- Labor to replace the thermostat: about 1–2 hours depending on access and shop rate; typical labor rates range from 75–150 USD per hour, totaling roughly 75–300 USD
In practice, the part cost plus labor usually places the installed price in a broad range, commonly around 120–350 USD, with possible variations upward if OEM parts are chosen or if additional services (like a coolant flush or hose replacement) are required.
Factors that influence the price
Prices are not fixed and can shift based on several variables. The list below explains common drivers of higher or lower costs.
- Geographic location and local labor rates
- OEM Mopar versus aftermarket thermostat parts
- Whether the thermostat is sold as a standalone part or as part of a housing/kit
- Engine variant in the vehicle (the 2018 Grand Caravan commonly uses the 3.6L V6, which can affect part accessibility and price)
- Whether a coolant flush, new hoses, or other cooling-system work is included
To keep costs predictable, obtain multiple quotes from reputable shops, ask what is included in the price (gasket, coolant, disposal fees), and consider whether you’re comfortable performing the replacement yourself if you have the right tools and instructions.
Summary
For a 2018 Dodge Grand Caravan, a thermostat replacement typically costs around 120–350 USD installed, depending on part type (aftermarket vs OEM), whether the housing is included, coolant needs, and local labor rates. Shopping around for quotes and clarifying what’s included in the price can help you find the best deal.
