Thermostat, Green Line

You should start by removing the Exhaust Manifold from vehicles with automatic transmissions before replacing a 2.2l l61 engine Thermostat. Begin by draining the cooling system before unfastening bolts that hold the Thermostat Housing to water pump feed pipe. Finally, remove the Thermostat Housing and its connected water pump feed pipe. Remove the Thermostat next step. Start with Thermostat placement before reattaching the Thermostat Housing to water pump feed pipe. Fasten and torque the Thermostat Housing to water pump feed pipe bolt until it reaches 10 nm (18 inch lbs.). When working on automatic transmission vehicles you must reinstall the Exhaust Manifold. Finally, fill the cooling system.

The first step towards changing the Thermostat is draining the cooling system. Then, take out the bolts holding the Thermostat Housing in place to the Water Pump feed pipe, then remove the feed pipe. Carefully but record due to a subsequent reinstallation, care for removed Thermostat and retaining sleeve's orientation. During installation, install and secure the Thermostat and retaining sleeve with dimple in the housing slot. Before fitting in Water Pump, the o-ring should be lubricated with soapy water or coolants. Replace the feed pipe joining Thermostat Housing to Water Pump, and adhere to the fastener notice in service precautions. Screw the bolt to secure the Water Pump feed pipe doing a 10 nm (18 inch lbs), and finally topping up the cooling system.

First drain the cooling system before replacing the engine coolant Thermostat. First you must move the radiator outlet hose clamp at the Thermostat Housing before you can take the radiator outlet hose off of the Thermostat Housing. You should start by removing the Thermostat Housing cover by taking out its bolts and the cover and then removing the Thermostat before discarding the Thermostat Housing o-ring seal. Begin installation by placing a new Thermostat Housing cover o-ring seal followed by installing the specified Thermostat. Apply 10 n.m (89 lb in) of torque force when installing the Thermostat Housing cover bolts. Secure the radiator outlet hose to the Thermostat Housing then position its clamp at the housing before you fill the cooling system.

To replace the Thermostat (LX9), start removing the air cleaner intake duct and partially drain the cooling system. Put the hose clamp pliers (J 38185) with a small adjustment of the hose clamp to take it off from the water outlet housing, then pull to remove the radiator inlet hose from the water outlet housing. Then, take off water outlet housing bolts as well as its housing, then the Thermostat. Clean and inspect the gasket mating surfaces of the water outlet housing before installing new Thermostat. Rerunning the water outlet housing, making sure the bolts are tightened to 25 nm (18 ft. Lbs.), and connect the radiator inlet hose to the water outlet housing. Use the hose clamp pliers (J 38185) once again to reposition and secure the hose clamp to water outlet housing followed by re-securing the air cleaner intake duct. Finally, fill the cooling system.

Begin by removing the intake manifold cover and draining the cooling system.

Reattach the lower radiator hose to the thermostat outlet.

Remove the thermostat housing to water pump feed pipe bolts and the thermostat housing to water pump feed pipe.

Remove the thermostat housing to water pump feed pipe bolts and the feed pipe itself.

Reposition the radiator surge tank outlet hose clamp at the thermostat cover and remove the radiator surge tank outlet hose.

Remove the exhaust manifold.

Tighten to 10 Nm (18 inch lbs.).

Begin by draining the cooling system.

Install the thermostat housing cover bolts and tighten them to 10 Nm (89 lb in).

Ensure to install the thermostat cover bolts and tighten them to 10 N.m (89 lb in).

Take out the thermostat and retaining sleeve, ensuring to note their orientation for reinstallation.

Install the thermostat housing cover bolts, tightening them to 10 Nm (89 inch lbs.).

Take out the thermostat cover bolts and the cover, followed by removing the thermostat and discarding the thermostat cover O-ring seal.

First, drain the cooling system using the appropriate procedures for the specific model.
