How to Change the Thermostat on a Sebring 2.7

The Chrysler Sebring 2.7-liter engine uses a mechanical thermostat to regulate the engine temperature. When the thermostat fails, one of two things can happen. First, the engine could overheat because the thermostat restricts the flow of coolant though the engine. The opposite is also possible; the engine could fail to reach the proper temperature because the thermostat allows too much fluid to flow through. Either situation can cause issues that cost much more to repair than replacing the thermostat costs.

Step 1

Place the Sebring onto a set of ramps, secure the parking break and place a clean drain pan under the radiator petcock.

Step 2

Open the petcock with a pair of pliers and drain two gallons of coolant from the radiator into the drain pan. Do not forget to close the petcock. Save the drained fluid to return to the radiator later.

Step 3

Follow the upper radiator hose to the engine. The hose connects to the thermostat intake housing located on the engine. Remove the hose by prying the clamp off with a pair of pliers and then by pulling the hose off the housing.

Step 4

Remove the two bolts that secure the thermostat intake housing to the engine with a socket and ratchet and lift the housing off the engine. If the housing sticks, use a small scraper to break the seal.

Step 5

Take note of the thermostat's orientation in the engine, pull it out and place the new thermostat into the hole with the same orientation as the old one.

Step 6

Scrape the old gasket off the bottom of the thermostat intake housing and then scrape the mating surface of the engine clean with the scraper.

Step 7

Place the new gasket onto the mating surface of the engine. Place the intake housing onto the gasket. Thread the bolts through the housing with your fingers and then tighten the bolts with the socket and ratchet.

Step 8

Slide the hose onto the Sebring's thermostat intake housing. Tighten the clamp into place with the pliers.

Step 9

Open the radiator cap on the Chrysler's radiator and pour the two gallons of fluid back into the radiator.
