loosen the bottom bolt with a 13 mm swival head socket, do not remove the bolt all the way, take out the top one and the thermostat housing will slide out and then remove the thermostat.
The thermostat on a 2001 Lexus RX300 is replaced by removing the upper radiator hose and unbolting the thermostat housing. The thermostat can then be removed, a new gasket installed, and the replacement thermostat placed in the housing.
The thermostat on a 2003 Pontiac Grand Am 2.2L L4 Ecotec is replaced by removing the upper radiator hose and unbolting the thermostat housing. The thermostat can then be removed, a new gasket installed, and the replacement thermostat put in place.
Follow the upper radiater hose from the radiater to the engine block. The part that the hose attaches to on the intake manifold is the thermostat housing. In the housing is the thermostat. Just two bolts attaches thermostat housing to the intake manifold which is attached to the engine block. If you replace the thermostat yourself make sure that you see how the thermostat was before you take it out. The spring side faces into the intake manifold. Drain some radiater fluid before removing the housing or you will spill fluid all over your engine block. Best to do this with the engine cold. Buy a gasket and high heat antifreeze resistent silicon gasket sealer when you buy the thermostat.
The thermostat for the 3.5 Liter is under a flange bolted to the top of the block (in the valley), connected to it is a black pipe that connects to the lower radiator hose. This flange has four bolts that are accessed only after removing the intake manifold. Removing the housing that connects to the upper radiator housing optional.
I had this problem. I solved it taking the car to my local scrap dealer and buying a bus pass with the £30 he give me
The thermostat on a 1999 Kia Sportage is replace by removing the upper radiator hose, unbolting the thermostat housing, and removing the thermostat. A new gasket can then be put in place and a new thermostat installed.
its very hard to get to. if you look down the firewall on the left side. you have to remove the heat shield. i wound up dropping the exhaust and removing the exhaust manifold because its mounted under the water pump which is under the manifold.
that is probably an oil pressure switch that you see. coolant temp sensor is usually near the thermostat in the manifold.
You cant chance the spark plugs with out removing the manifold sorry dude i have tried every possible way there is and its not going to happen :(
It is not in the valve cover, as on other Focus engines. It is on the side of the engine, under the intake manifold, plugged into the "oil separator". It is possible to reach it from underneath, albeit blindly, if you have the car on a rack. The service manual suggests removing the intake manifold to get to it. The difficulty in reaching it may have something to do with the service schedule for replacement being set way out at 100,000 miles.
This is a 15 year old vehicle. The thermostat is very cheap insurance. Just replace it when performing a cooling system service. Replace it by removing the old thermostat, carefully cleaning off the old gasket. Install the new gasket & thermostat, spring toward engine block, and tighten to factory specs, and no more.
Where the top radiator hose goes to the engine there is a two-bolt housing that the hose is connected to, that is where the thermostat is . After the engine is cool, drain enough coolant from the radiator so when removing the two housing bolts you don't lose a lot of of it. After removing the 2 housing bolts You should find your thermostat setting in the intake manifold for the 4.0 and just behind the housing in the 3.0 just give it a little twist and it should come out then.
